System requirements:

  • 2GB RAM (4GB recommended for a comfortable usage).
  • 20GB of disk space (100GB recommended).
  • 1024×768 resolution (on lower resolutions, press ALT to drag windows with the mouse if they don’t fit in the screen).

Upgrade instructions:

  • This BETA release might contain critical bugs, please only use it for testing purposes and to help the Linux Mint team fix issues prior to the stable release.
  • Upgrade instructions will be published after the stable release of Linux Mint 21.
  • It will be possible to upgrade from this BETA to the stable release.
  • It will also be possible to upgrade from Linux Mint 20.3.

Bug reports:

  • Bugs in this release should be reported on Github at https://github.com/linuxmint/mint21-beta.
  • Create one issue per bug.
  • As described in the Linux Mint Troubleshooting Guide, do not report or create issues for observations.
  • Be as accurate as possible and include any information that might help developers reproduce the issue or understand the cause of the issue:
    • Bugs we can reproduce, or which cause we understand are usually fixed very easily.
    • It is important to mention whether a bug happens “always”, or “sometimes”, and what triggers it.
    • If a bug happens but didn’t happen before, or doesn’t happen in another distribution, or doesn’t happen in a different environment, please mention it and try to pinpoint the differences at play.
    • If we can’t reproduce a particular bug and we don’t understand its cause, it’s unlikely we’ll be able to fix it.
  • The BETA phase is literally a bug squashing rush, where the team is extremely busy and developers try to fix as many bugs as fast as possible.
  • There usually are a huge number of reports and very little time to answer everyone or explain why a particular report is not considered a bug, or won’t get fixed. Don’t let this frustrate you, whether it’s acknowledged or not, we appreciate everyone’s help.

Here are the download links:

Integrity and authenticity checks:

Once you have downloaded an image, please verify its integrity and authenticity.

Anyone can produce fake ISO images, it is your responsibility to check you are downloading the official ones.

Enjoy!

We look forward to receiving your feedback. Many thanks in advance for testing the BETA!

  1. 1) In GRUB menu, there isn’t anymore “Hardware Detection”, “Boot from local drive” and “Integrity check”.

    2) I choose “Paris – France” and after, the content of the next window (“Disposition du clavier”) should be in french language but the content is in english, it isn’t anymore in french.

    3) I choose “French – French (AZERTY)” keyboard but when I write a username and a password, keyboard is still QWERTY.

    4) Installation can’t start in VirtualBox, there’s an error (“Input/output error”) and install software crashes..

    2. I don’t understand why people test an operating system in a VM instead of using the live mode? Because that is exactly what this mode is for. VM are completely unsuitable for this and a bug report is practically worthless.

  2. Would like to know the version of KDE used. Their latest releases had great improvements, I do really miss on my 20.3 Mint.

    Reply

    1. Mint 21 uses the Ubuntu Jammy (22.04) repos, that means KDE 5.24 (released this past February) is available.

    3. I am using Linux mint from 5 yrs. I am very comfortable with it. I loved 20.3 version and very exited for venessa stable.

  3. I installed it in a virtual machine. I haven’t noticed any issues so far, aside from an issue that was already present in Mint 20 that I wasn’t expecting to be fixed.

  5. Very good release LM21beta!
    I tried much about “blueman-applet”. How getting the blueman-icon greyed-out (= bluetooth deactivated) at the panel after booting system? If deactivating blueman-applet in “start-programmes”, there won’t be be a greyed-out icon at the panel afte boot… It would be good, if it’s working like “network-applet” = always visible at panel for activating or deactivating…
    Btrfs-on-Luks with @, @home, @cache, @log & @swap subvolumes & tmpfs for /tmp is working pretty good, but it is not out of the box… Future will show which filesystem-direction Mint will go…
    Kind regards

    1. More likely to be ZFS as that is what Ubuntu are working on. It’s there as an experimental file system choice on the main Ubuntu version ISO installer but not all of their ‘flavours’ like Kubuntu, Xubuntu etc.

  6. Good question. I think for mobile phones you need ARM version?
    It would be nice to see in future ARM architecture version of Linux Mint.
    Maybe try Ubuntu Mate armhf/arm64 version for Raspberry Pi?

    Reply

    1. ARM requires support for ARMv5 or ARMv6 or ARMv7 or … The Raspberry Pi OS has several versions are a result, an old ARM 32 bit for older Pi chips and a new 64 bit limited to only some new Pi chips plus an Intel Pi OS for those who want the same OS on their desktop. Firefox tried to compile a 32 bit version for ARM on the Pi but it only works on some Pi chips because they chose the wrong ARM 32 bit version. Linux Mint would end up having to support several ARM versions on the Pi plus lots more across other ARM computers.

  7. I have a couple of observations (after reading the guideslines they are probably not bugs):

    1) Double-clicking on the boundary between the top of the title bar and the background no longer maximizes the window vertically.

    2) Firefox and Chrome (I use if for video playback on my old computer) no longer remember their positions between launches.

    Reply

    1. 1 still works for me but it does depend on the window. It doesn’t work on applications that use header bars (csd windows like calculator) but does work on the ones that muffin draws the decorations for (ssd windows like gnome-terminal).

    2. I have configured Firefox and Chrome to use the system title bars. Mint Cinnamon 20.3 doesn’t exhibit this behavior. I can live with it if that’s the way it’s going to be.

  8. I neglected to mention in my previous post the I’m using the Linux Mint 21 Cinnamon Beta Live USB only.

  9. Japanese input (fcitx-mozc) works well. The tray menu looks better than before. After restarting cinnamon, but thats a detail.
    Thank you so much for moving slowly forward and keeping the standard high. And good luck with all the coming bug fixes 😉

    1. The version of eCryptfs package included in the universe repository is 111-5, the same as allegedly fixed Debian package.

  11. Fractional scaling under Cinnamon 5.4 looks much better on a WQHD screen compared to Cinnamon 5.27, not being blurry anymore. That is a great improvement, thanks!
    Is Cinnamon 5.4 also going to be available on LMDE 5 in the future?

    Reply

  12. I use Linux LM 20.03 cinnamon and Google Chrome（Official Build）and when open “Save as…” dialog, I’d rather prefer to just hit Enter button to confirm my choice. Instead it’s not on focus, so I have to move my cursor to the Save button and press it, since no hotkeys let me focus this dialogue.

    I found this problem on every Chromium based browsers (Opera, MS Edge etc.)

    I rollback to LM 20.2 and no such problem found.

    I tried to upgrade LM 20.2 to 20.3 and the problem occur again.

    I am sure this issue is related to LM 20.3

    And now, I run LM21 beta and found the same problem as described above. Anyone can help? T_T

    Reply

    1. ALT && TAB to get the window in focus and then SHIFT && TAB to activate the Save-button… I would just use the mouse instead.

    2. May not be strictly beta related but can confirm this issue started for me a few months ago too. Can’t remember if it coincided with any upgrade but I AM running 20.3 now. Confirmed on current versions of Chrome / Chromium / Opera.

      Firefox works as you’d expect (brings Save As dialogue box to immediate focus after opening) while Chrome opens the dialogue box but the background browser window remains in focus. Really annoying little papercut as there seems no way to easily bring the Save As box to focus except Alt-Tab away and Alt-Tab back again.

  13. I tried installing themes made for Gnome like ‘WhiteSur Gtk Theme’, and they are finally working much better!

    Thanks LM team!

  14. Hi Clem!

    Thanks for the new release!
    Maybe this was already explained, but maybe i missed it…
    Why can’t we choose differnet themes for windows vs controls?
    This was a feature i really liked… maybe others like it also.

    Cheers!

    1. “Although the Mint-X and Mint-Y themes did their best to make their GTK titlebars and shadows look as similar as their Metacity counterparts, in practice these were rendered by two different engines within Muffin and it introduced a slight visual disparity between the two types of windows.

      In Cinnamon 5.4 all windows are now rendered with the GTK theme, whether they have a headerbar or not. Metacity themes are no longer used”

  15. no thumbnails with s10 plugged in usb when viewing videos and pictures on linux mint cinnamon 21

    Reply

    1. Make sure in the Nemo preferences on the “Preview” tab you have show thumbnails set to yes and not local files only.

  16. Installation in recovery mode mandatory on a Clevo N7x0WU laptop with Intel UHD Graphics 620 CPU and GPU.
    The screen flashes, it is impossible to use it.
    Very disappointed, back to 20.3 which works perfectly

    Reply

    2. After research Kernel 5.15 doesn’t work with Intel UHD Graphics xxx GPU.
      A lot of ubuntu 22.04 user are concerned
      Must use kernel before 5.15 or since 5.18

    3. With regards to the screen flashing have you tried disabling the PSR (panel self refresh) tuneable for the intel driver?
      https://ljvmiranda921.github.io/notebook/2021/09/01/linux-thinkpad-screen-flicker/

      if it’s other issues related to Intel graphics, it may be this:
      https://github.com/pop-os/linux/issues/86

      where the workaround for 5.15 kernels is to disable Vt-d (I/O virtualization)
      they report it’s fixed in newer kernels

      Given all the reports (the PopOS bug cited above was since Dec, 2021 on kernel 5.15.x) and lack of features that made the cutoff, I think using 5.15 for Ubuntu LTS was mistake, even if it’s declared in mainline as long term.

      Even Canonical themselves stated the plan for OEMs and HWE kernels (used for hardware support) is to use kernel 5.17 — and was since Jan!

  17. “In Cinnamon 5.4 all windows are now rendered with the GTK theme, whether they have a headerbar or not. Metacity themes are no longer used.”

    On LM20.3 I have been using Mint-Y-VBB (Very-Big-Buttoned) theme variations by smurphos – https://github.com/smurphos/Window_Borders_Mint_19/

    This has Close/Maximise/Minimise buttons 100% larger than the stock Mint-Y window borders themes. Good for my old eyes. But those themes appear to use Metacity.

    So it looks like Mint-Y-BB and Mint-Y-VBB won’t work with the new version of Cinnamon. Would be great to have bigger buttons available as part of Mint

    Reply

    1. Agreed, I was also a user of Mint-Y-VBB which were really excellent… I really don’t get why they are so insistent on tiny little buttons (they used to be even smaller in Mint 19!) Maybe I’ll ask Smurphos on the Forums how I can manually “patch them in” to the new Mint themes.

    2. I use them too and find the small butons and sliders an absolute pain in the neck. I also have old eyes (and hands) – please make some allowance for us!
      I would like to hear if you get an answer, spamegg.

    3. I will look at changing over in LM 21 if you find the solution. Could you start an entry in the forums to record your progress?

      I will also look for OK/Cancel/delete sets to be different colours.

  18. When I press ctrl + alt + up to get the workspace overview on an empty workplace, the overview is not shown. Instead, the screen becomes just the wallpaper (no panel).

    ctrl + alt + left/right lets me switch workspaces. If a workspace has open applications, the overview appears. If there are no applications open, it’s impossible to leave this broken state.

  20. What has happened to xplayer – I can’t find it in Synaptic or Software Manager? (Mint 21 Cinnamon).

    Celluloid is OK, but I regularly find the “Properties” pane of xplayer very useful.

    Reply

    1. Hello Paul:
      I miss Xplayer as well but it has been retired. I was able to run it in LMDE 5. It will not run in Mint 21 because of python library requirements. I tried doing it and it kept crashing.

  21. Just want to say a quick thank you to the Mint team for their great work in general. Good luck to everyone on the bug hunting! I don’t have the time to hunt with you this time, but I will instead make another donation. Looking forward to the stable release!

  22. Dual monitor support is again problematic.
    I set my primary monitor on the center and secondary monitor on the LEFT. It works.
    Now, if I disable (from display utility) my secondary monitor and enable it again, then it defaults on the RIGHT (doesn’t keep my previous settings). This problem remains from Mint 20. Still not fixed.

    Reply

  23. Linux Mint 21 (beta) – So now when you pin an icon to the panel, it goes into the system tray! Why do that? So muscle memory is messed up in Linux Mint the same as it has in Windows 11 now. There is absolutely no reason for this.

    Reply

  24. Hi,
    I tested LM 21 Cinnamon beta. Lot’s of goodies and polished corners here and there, particularly happy about epub thumbnails (I have a huge library of ebooks), thank you in advance! I’ve spotted a few things to improve but I did testing from a pendrive in live session and didn’t apply any upgrades, so perhaps my observations are not valid anymore. 1) Libre Office is unusable in dark mode – there is only one icon set (Colibre), several dark icons are not visible in writer; 2) When I right-click on the window titlebar (in any window), I get a dark pop-up window (with all those ‘minimize, maximize’ etc options) even though I use the light theme globally; 3) ‘Start menu’ and software manger take longer to open – not a drastic delay. Looks like a very nice release 🙂

  25. Nothing wrong with the fresh install and nothing new either. Kernel 5.19-rc6 works as is it was 22.04. Previously, the smallest header was broken. Now the four packages compile ok.

    Hey, this is a Jammy base system and should be Wayland default:

    loginctl show-session $(loginctl|grep $(whoami) |awk ‘{print $1}’) -p Type
    Type=x11

    Along will have to wait and is there a way to enable Wayland?

    Reply

  26. Hi!
    First of all, as always, thank you for your great work!
    Had a quick look at the Live-usb-beta (so propper install might differ?) and noticed a few minor things:

    1. Panel-Settings as well as Time&Date-settings windows seem to be missing a few pixel in height and thus display an unnecessary scroll bar.

    2. Sound settings: Soundtest allows me to click 8 loudspeakers + sub , with no discernable change in wich speakers it uses, although output is set to stereo.

    3. Default soundcard and wifi power saving options are a bit to aggressive for my older hardware thus resulting in clicking sounds whenever a before and after a sound file is played and occasional wake-up problems for the wifi card when watching a buffering video. Now, I know how to deactivate the power saving through some file editing, but it would probably be a much better experience, especially for never users, if there was an option to delay or turn of the power saving for sound or wifi via gui in the power saving settings window.

    The new Thumbnails are very much appreciated, btw!

  27. Looking good, just installed the beta21″alongside” Mint 19.3 Cinn. and 20.3 MATE all on separate HDDs. Good ol’ Grub. Sure would like to see a Mint with LXQT. but this 21 seems faster than the others.

  28. Small graphic bugs for example angles show all windows freezes the desktop today i found that the grub customizer software no longer works even when i click do not show other operating systems and also do not show the grub menu all this no longer works why?

  29. Hi Team, thanks very much for the Mint21 Cinnamon beta release.

    I would like to suggest that the Disks utility would be more appropriate in the Administration sub-menu, rather than Accessories or Preferences, where it appears at present in the default Mint Menu.

    Also, Advanced Network Configuration and Firewall Configuration could be moved from Preferences to Administration.

    Reply

    1. I thought at one time there was a project to re-assign categories but I couldn’t locate a reference to it.
      You might also suggest here: https://community.linuxmint.com/idea/welcome
      In the meanwhile there is a way to do the re-assignment yourself by copying the desktop item of interest from /usr/share/applications to ~/.local/share/applications and use nano to change the Categories=
      If you use Xed, it will rename the desktop item.
      When everything is done back up your collection so you can copy it back over on a fresh install.
      After you are satisfied with your changes be sure to execute the command “update-desktop-database ~/.local/share/applications” to generate mimeinfo.cache in ~/.local/share/applications

    2. Thank you for the detailed instructions and the ideas link, which I will try. I think it would be worth making the Menu more consistent with the System Settings, although the categories are slightly different.

  30. Made a bootable Linux Mint 21 Cinnamon Beta USB stick on another Mint machine using the USB image writer. Booted from it. Something in the boot process writes to USB stick and it never boots the second time, unless the ISO is rewritten to it (on another Mint machine with USB image writer).

    Reply

    1. I’ve tried duplicating the failure you mentioned and cannot reproduce it.
      The Linux Mint live session creates another partition, the third one, on the USB stick “/writable” where logs are stored on each boot. After 5 boots they are at 667 MB.
      What is the capacity of your USB stick?

  31. There should be a separate “Get help by joining #linuxmint-help” irc channel, and a separate “just launch the irc client” buttons. The automatic join feature is not mentioned anywhere, nor how to not disable that in order to not join automatically with your desktop username, if you just want to launch the IRC client. Besides I don’t think the attitude of the people in that channel is up to any Code Of Conduct, as it clearly says anyone can join and make suggestions, and I feel after that experience I don’t want to donate money to Linux Mint any more because of the sneerful attitude.

    Reply

    1. Let’s please not troll on about the #linuxmint-help channel. Its just not constructive. You have no idea the over abundance of “Mr. Obvious” questions that are asked in there that could be answered with a web browser search. No one is perfect and the limited people who help there have their limits as any human would. The Mint Forums are a much better place to obtain detailed help and to make suggestions. IRC is just another tool.

    1. Most likely before the end of July, but not before the known major issues get fixed. No one wants buggy ISOs. 🙂

    2. As as “Senior Software Developer” you should know by now that Mint is released “When its ready”

    1. Could you please be more specific? Which desktop edition? What version were you using before trying the Beta? If you could link a screenshot of what are talking about that would be most helpful.

    2. I think dd means that the “Window Borders” control in the Preferences/Themes dialog no longer exists. This is presumably because of the change to using GTK – quote from blog: “In Cinnamon 5.4 all windows are now rendered with the GTK theme, whether they have a headerbar or not. Metacity themes are no longer used.”

    4. I hope not, because we couldn’t use many GTK3 theme that didn’t provide metacity window decorations.
      This change was overdue since a long time as far as I’m concerned.

    5. @François Blais
      The only issue I have with dropping metacity is that in LM 19 & 20 I could use the metacity Big Buttons and Very Big Muttons provided by smurphos (https://github.com/smurphos/Window_Borders_Mint_19/). These allowed me to have 50% or 100% larger Minimise/Maximise/Close buttons in app windows. Very helpful for people with imperfect vision.

    6. A good point, Tony W.
      However, that may be a job for the Mint Team to provide themes with larger window decorations.
      On Gnome-look.org, some programmers, like Vinceliuice, are already providing some themes with HDPI and XHDPI variants (when you use the install script).

  35. Has anybody experienced that since LM20 the installer creates UEFI partition on certain machines with plain BIOS (without any UEFI) and after reboot the system hangs with “unsupported filesystem” error?
    (LM21 also)

    Reply

    1. Have you paid attention when choosing the partition table type for your harddisk? you should choose MS-DOS instead of GPT (UEFI) if your system doesn’t support UEFI

  36. In the Cinnamon terminal, Edit – Select All now only selects the last page of text.

    In Mint 20.3, Select All includes the whole scroll-back buffer.

    Is this an intentional change? Selecting a page of text is trivial with the mouse, whilst recording a day’s work might involve scrolling back through thousands of lines.

    Reply

    1. Hello Mike:
      This was a result of an upstream change to gnome-terminal. Yes, frustrating I know.

    6. Ah, thanks again Harry. I see I accidentally tried mate-terminal on Mint 20.3!

      It fails on Mint 21 :o(

    7. This is terrible as when I download an ISO and verify that ISO I like to make a copy of the terminal session pasted into a Text File and this Select All behavior needs to be restored to its nominal behavior or I’ll have to remain on Mint 20.3 until that is remediated. There are times when I’m dong a journalctl -b to look at the full boot log and that new behavior will make any by the page copies of that a total no go there as well! Also for reporting errors the ability to copy the contents of that entire terminal session is very necessary there.

      This is a must fix for a lot of Mint Help Forums where things need to get queried from the terminal and cut and pasted to the persons asking for that content.

  38. Sublime Text does not work. It asks for a license and closes.
    Tested with both the official package and the flatpak versions.
    It works fine on ubuntu 22.04.

    Reply

    1. The version of Sublime-text available on Ubuntu 22.04 is the Stable Channel, Build 4126
      Same as in Mint 20.3 (Una) sublime-text_4126_amd64.deb

      Since it is no longer in 22.04 as a Debian package, Linux Mint provides the Development Channel version 4131 as part of the ‘mint-dev-tools’ package.

      The difference is the Development Channel version does not allow unlimited evaluation.

      As a work around, you could get the Debian package from:
      http://packages.linuxmint.com/list.php?release=una
      Scroll down to “Import” sublime-text 4126 , download and install.
      Be sure you purge the other version first.

      In the meanwhile, I will file a bug report and see what happens.

  39. Hey, just wanted to make a proposal about naming the editions of LM. To me women’s names always had this connotation of a substitute partner for lonely men with their computers. Remember when the Amiga (Spanish for ‘girlfriend’) computer came out? Kind of cringey. Soon there will be LM ‘Zoe’ or something. Why not start with the names of celestial bodies/constellations after that? Like ‘Aldebaran’, ‘Aries’, ‘Arcturus’.

  40. “new features in LM 21 cinnamon” printing improvements section says “disable printerless printing/scanning”, is it meant to say “driverless”?

    Reply

  41. Just a tipp for the next Cinnamon: create “better shortcuts”. I mean, the link that points to a folder on another drive works only with mounted drives. If this is not mounted automatic after the next boot the becomes “broken”. Opening it, got “the link is broken….” message instead “wait a bit, mounting the drive” 🙂
    (I know, fstab, automount, for me it’s not a big problem, but…)

    Reply

    1. Scott: The issue you are describing is so vague. Have you downloaded all the latest updates? There were some this morning for Cinnamon and mutter. Could you please check the bug tracker and see if it has been resolved and if not, file a bug report against it? https://github.com/linuxmint/mint21-beta/issues
      The window to file and get a bug resolved is fast closing.

  45. THX!!!!! 125% SCALING LOOKS GOOD AND YOU GOt rid of that weird thin border in new mint-y theme. thank you thank you!!!!

  46. Dear LM team,
    first of all thank you for your hard work and delivering this excellent, rock stable and reliable linux distribution.
    I am testing LM21 in VM and have found no major issues except this minor ones:
    1. I am using cinnazor theme (https://www.gnome-look.org/p/1586159/) and the window buttons (minimize, maximize, close) are doubled in size for some “native” apps, like terminal, nemo, apps under preferences. The others like calculator, calnendar … looks the same as in LM20.3. This theme is probably kinda weird, because all other themes are ok.
    2. as mentioned above, transparent panels fails in LM21

    I can happily live with this minor issues but there may be some other users using some weird themes like me and you may receive a lot of complaints after final release. Just to let you know.

    Thanks,
    Almair

    1. I’m not speaking for the Mint team, but this is a third party theme.
      It’s the author’s duty to make it compatible with the latest Cinnamon version.

  47. A simple suggestion. In Nemo (Cinnamon), Caja (Mate) and Thunar (XFCE), the double click on a free region is not implemented: it could be used to go directly to the parent or previous folder to make the navigation easier.

    Reply

    1. Hello GEO
      In Nemo you can enable this. Under “Edit/Preferences/Behavior” check the box that says “Double-click on a blank area to go to the parent folder”.

  49. I’m using it as a production environment.
    Programming in Java, I use Eclipse, MySQL and everything works fine.
    Interface with eye-pleasing colors.
    Excellent system!
    No bugs found.

  50. Harry,

    Harry,
    Sorry for being so vague Newbe. Updates installed, but still does not work. I did not see the issue in github, so I added new issue. Issue number 157. When I go to Extensions and download and install transparent panels it does not work with default theme or other themes. Works great in 20.3. If you need something else let me know and I will try to provide. Remember still new to linux but willing to try.

    Reply

    1. Okay. Thanks Scott for filing the issue. I think it is up the extensions developer to make the changes necessary for the new version of Cinnamon. The cool thing about Linux is your learn more by doing stuff. We’ll see what the word is in GitHub. Don’t ever feel bashful about stepping forward on an issue.

    1. I solved this problem. You need to install the google chrome package from the repository. After that, the integration works.

  53. Good thing is, bluetooth works on 21 Beta with some PCs that previously did not work well on older Mint versions. The downside is, bluetooth on 21 Beta fails to work on multiple PCs such as on an iMac where 20.3 did work adequately.

    The 21 Beta bluetooth taskbar icon gives popup notifications when a device is connected, it should likely be in bold, as the text how many devices are connected has b and /b tags surrounded by lt/gt symbols. Also when a device is connected, if you click the taskbar icon to get a list of bluetooth devices to detach for example, there are empty menu items inserted every other line. It may or may not relate to the PC having two Bluetooth interfaces.

    The bluetooth subsystem sees both iMac internal and external USB bluetooth adapters. Trying to use the iMac internal adapter hangs searching for devices and none found, only the external USB adapter works.

    21 Beta on an iMac, the headphone connector gives out no sound (some config hack needed), and the display backlight is not controllable by the taskbar applet, even if the brightness control symbol is there and brightness slider can be adjusted with mouse (did not work on 20.3 either).

    On an HP netbook with touch screen, the touch screen does not work any more in 21 Beta. It used to work in earlier release, but it does not in 20.3.

    All tested 21 Beta and 20.3 versions were Cinnamon, non-edge.

  54. Overall, there is a huge delay trying to boot LM 21 Cinnamon Beta on all PCs from USB stick, compared to LM 20.3 Cinnamon

    1. Here is a discussion about it:
      https://github.com/linuxmint/mint21-beta/issues/36

      Did not see the long boot times this user mentioned but there is a definite increase in live boot time on the same hardware. When seeing how long the live boot time was when Ubuntu 22.04 came out wondered how Linux Mint would be able to trim the boot time down. Not running the snap daemon helped but there are some other things. Some services like casper-md5check.service can be turned off while others are unavoidable.

  55. You can also use the graphical Cinnamon menu editor tool (hidden by default) to customize the menu entries to your taste.

  56. Tried both dd and ventoy method of making the live usb out of several iso(s) downloaded from several countries, still giving me the same “load kernel error”, long time ago, 20.x beta isos never gave me this kind of problem.

  57. I solved this problem. You need to install the google chrome package from the repository. After that, the integration works.

  58. Binding windows to the set location does not work when configured manually, everything worked before in mint-20.3, after opening the browser opens in full screen although it should remember the location.

  59. Wine does not work, and it was the same situation when it was released LM 20, two years ago. Do not recommend it, or correct the problem. it’s not funny to muck up the system.

  60. I tried this mint21 Cinnamon, and I found the most hotkey trick wouldn’t work on this.
    I usually use “ALT + space” to trigger window menu (or System Menu), and then press ‘C’ to close window. (alt+space, then ‘c’,)
    This operation is quite fast than “ALT + F4”.
    But in Cinnamon, the press ‘c’ can’t select [close]. I have to use arrow to select [close] and press ‘enter’ to apply the [close].
    May I know where can I report this issue ?
    Thanks,

  62. System Settings –> Effects

    Setting the “Closing windows” effect to “None” results in windows becoming stuck/remaining visible after they have been closed

    1. You’re right! I can reproduce the issue. The BETA bug reporting is now closed, so we will have to report this after the Stable version is released.

  63. I’m always excited for a new generation update…. 🙂
    I will jump right into testing the Beta.
    I also hope one day a feature will be added to not auto-discover printers. When I go into a network with 20+ printers, I have to watch all those pop-ups AND I have to wade through all those printers to find the one that I want to print to rather than being able to set up just the one printer I want to use. It would be nice to have the control to only install and see the printers I want to use.

    Hopefully it will come one day but I still can’t wait to test drive 21. 🙂

    1. just turn it off, that is the first thing i do when i setup a new PC with Linux Mint for our company.

      sed -i ‘s/BrowseRemoteProtocols dnssd cups/BrowseRemoteProtocols none/’ /etc/cups/cups-browsed.conf
      this will stop auto-discover 😉

  64. During the night I was shown over 900 updates in Mint 20.3. So that meant that Mint 21 was officially ready. The end of the story: Nothing works anymore. More than tty1, where I should log in, I do not see. Logging in with username and password doesn’t work either. Back into Mint 20.3 doesn’t work either so far. I will probably need some time to get it working again.

    1. Can anyone confirm that also on their system the updates in Mint 20.3 show that Mint 21 is released?

    2. I’m not sure what happened on your side, but I just did a regular update on my installation and I can confirm that my LM is still at version 20.3.

      Also, upgrading between versions of Linux Mint normally does not take the same steps as regular updates. First of all, the Update Manager software will detect and say that an upgrade for itself (Update Manager) is available. If the upgrade path to the next version is available, the option to do so will be inside one of the drop-down menus on top (it will not have a big button like the refresh and install buttons iirc). Again, I’m not sure what happened on your side, but if you didn’t do anything that sounds like what I just described, it probably wasn’t an upgrade to 21.

  66. Could someone please post what’s entered into Terminal to update Beta (LMC-21) to stable? Thanks a bunch in advance!

    1. Beta –> Stable happens automatically. Nothing needs to be done other than the standard updates you would normally do anyway through Update Manager. The only time something else needs to be done is going from version to version, such as 20.3 to 21. At that point, they will release the new upgrade tool. But if you’re already on 21 beta, you’re good to go. Since the ISO has already been approved for stable release, you’ll be on stable soon, if it hasn’t already happened by the time you read this.

  67. @ Yonda Entrepin:
    Thank you very much for your description. Exactly that was what I expected.
    But it wasn’t like that on my system.
    Over 900 updates, about a little more than 800 MByte, including Kernel 5.15.25 (the ’25’ as far as I remember)
    Also as far as I remember it came from the Ubuntu archive. Normally that is not my choosen server.
    I’m here in Germany, so I take german servers.
    As far as I see it my bootloader is messed up somehow. I’m going to try to fix it with the Boot Repair Disk.
    If that doesn’t help I might set up the whole system from scratch, when the official LM 21 will be released.

  68. Yay, 21!!
    With using girl’s names it must be inevitable for Mint users to stumble over the name of an ex for better memories or worse. Couple of times over the years it’s been – well, ok, its just a name you know.

  70. Hello. Tried to do a early install of LM21. Installation failed, twice. Had to timeshift myself back to LM20.3. That at least worked. It was not the first time I tried this early and it never went wrong. I will go with my original plan A and wait for the official release and upgrade. But right now, I am not optimistic. My laptop is a System76 made to run linux and never any distro installation failed. Very disappointing.

    1. Timeshift is a lifesaver… I’ve restored my broken system a number of times with it.

  72. Hi Linux Mint team.
    A fault occurs while moving panel in Linux Mint 21 (his is a regression)
    Reproduction steps:
    — Right click on the panel, choose Move
    — Choose left side in the screen
    — Right click on the panel, choose Move
    — Choose top side in the screen
    In this case the icons of left side on the panel they pile on top of each other.
    This operation in Linux Mint 20.3 works well.

  73. Hello,
    I upgraded to Linux Mint 21 from 20.3. Thanks for this new version!
    However, I noticed that the CTRL key I used to use as the “Modifier to use for toggling between tile and snap mode” did not work anymore.
    I went into the “Window Tiling” options but noticed that there are now much fewer options in there as there used to be and I am unable to set this Modifier.
    Is it just me who is seeing that ?
