MX-21 KDE (plasma) beta 1 iso images for testing

MX-21 KDE is built from Debian-bullseye and MX repositories and features the plasma desktop and an emphasis on KDE and Qt based applications. MX-21 KDE is a 64 bit only release.

–direct download of testing images:

<64 bit KDE/plasma with Debian standard 5.10 kernel> sha256_checksum md5_checksum signature

KDE/plasma release-specific things that are new in the beta 1

–Plasma 5.20
–Docking icon entries on plasma panel
–Discover in place of muon.
–Discover is used for update management.
–Ksnip for screenshots (replaces spectacle)
–General performance improvements, especially on live media.

General things that are new in the MX beta 1

–New and updated applications
–New installer partition selection area, including some lvm support if lvm volume exists already
–New UEFI live system boot menus. Now you can select your live boot options (persistence, etc…) from the boot menu and submenus rather than using the previous console menus.
–User password (sudo) for admin tasks by default. You can switch this in mx-tweak->Other tab.

With this beta 1 release, we are particularly interested to continue testing the new UEFI live system boot menus along with the installer. Virtualbox testing is welcome, but we are looking for edge cases on real hardware for the most part.    Any errors and/or bugs resulting from the KDE/plasma configurations are also of particular interest for this release.

Known issues

–the wallpaper is a little busy and the current conky gets washed out a little. looks better on some screens than on others. That will get worked out after default wallpaper is chosen.

–MX Package Installer: test repo and backports tabs will not display anything, for obvious reasons, the repos don’t exist or are empty at this time. Feel free to test popular application installations though.

  1. Hello
    Sorry for not not reporting bugs and asking a question instead but it has been bugging me that the XFCE beta was release before the release of debian 11 bullseye. Does this mean MX21 would be based on a pre-release version of bullseye instead? If yes, then will this affect the stability in any way?
    Thank you

  2. This is a very possible security leak,(–User password (sudo) for admin tasks by default. You can switch this in mx-tweak->Other tab) a quote from your mx 21 KDE page. This enables anybody at your console to change ROOT. No Sudo needed no pass word needed. This is from a Beta install Of KDE mx 21. This is all done in Home.

    • that would only be true if the sudo password has already been used once. if you want to shut down other users, remove them from the sudo group.

    • just install it and don’t worry too much about the filesystem. I use ext4, but others are available. the system is set up to automatically run a “trim” command once per week for ssd maintenance. some will tell you not to put swap on a ssd. I tend to disagree, and keep my swap on my ssd. ssd reliability has come a long way in the last several years.

  3. Just installed on my XPS L321X and it went beautifully. I’m looking forward to playing with it. Thanks for all the hard work.


  4. (intel 10400/GT 730) I have one interface that sometimes starts blinking. It all started in Firefox (reinstalled) then it was in other programs as well. The windows blink, or they are not visible at all. LogOut helps. Is it because the beta and the interface is slowing down or because of the hardware

  5. I am a big fan of MX Linux, especially KDE Plasma version. Previous version had a problem regarding “sharing folder in KDE/Dolphin”. This is fixed now in MX-21 KDE (plasma) beta 1 Release. Special thanks to MX Development Team.

  6. can we upgrade from mx linux 19 to mx linux 21 without reinstall it?


    please provide us with tools to upgrade from the mx 19 to the new mx 21 .thanks

    • pretty sure this is fixed on beta 2 (not released yet) or by updating the mx-installer before installing beta1. but in short term, use dolphin –new-window to launch a new instance and after that you should be good.

    • kinda depends on how low spec. the build has pretty good ram usage but netbook type machines (2gb ram) may struggle, and don’t forget KDE/plasma/Qt uses graphics acceleration so while the cpu hit isn’t too bad, you may lag if your graphics are lousy. pretty much like anything else.

  7. So far, the only issue I’ve run into is that it won’t automatically connect to a known WiFi network. It remembers the network and password, but I have to tell it to connect. I’ve made sure the option to connect automatically is selected, but it doesn’t. I’m going to do a bit more digging before I try to file it as a bug. I’ve never filed a bug report before so this will be a new experience.
    I have been using MX on my xps L321x for a long time and look forward to continuing that. Thanks all for the hard work.

  8. I haven’t seen anything listed anywhere else so I’ll ask here.

    Have the MX team elected to go with Secure Boot enabled for 21?

    I run a firewall and ESET secure endpoint for malware which checks for most malware including rootkits so as much as I love MX it would not drive me away if the answer was no. I’m just curious.

  9. PS.. I’m glad D.O.’s response to “when will 21 full be released?” was “WHEN WE’RE READY”

    I wish Microsoft and most other Linux distro’s abided by that.

    I’ve played with Linux for over 15 years and done the distro hop like everyone else.

    However, I think most of why we all do the dance is because of stability issues.

    Yes, it’s nice to play with the latest apps but if the system crashes and is less reliable than Windows what’s the use?

    I love the way MX has its 4 pronged release approach to have stability first then the newer apps after they’ve been QA’s by the MX team.

    I’m an independent insurance agent so I am busy enough as it is without taking the time to research why a Linux distro has crashed on me multiple times. I’ll have to install VMware player to try v.21 as I’ve only got 1 laptop and I don’t want to crash it.

  10. Where is “Virtual Keyboard” in Application menu? I can use virtual keyboard in Login Screen. Is it possible to access virtual keyboard in LibreOffice?

  11. The NVidia Driver Installer tool runs as root. Sudo should be used for this script since there won’t be a known root password on install.

    Also noticed that the Gnome Document Scanner is installed by default — this should really be changed to Skanlite on a KDE desktop.

    • it just says that there is a second partition selected as ESP in the installer. sda1. its not in your screenshot. you can use the “use for” box to select a blank entry to de-select it. the partition will not be touched.

  12. hi there, mentioned thread is locked already, so i write here. i use kde beta1 as primary os for work and seems stable as far. however i realized problem with suspending pc and language and formats. suspending pc works with unpredictable state, sometimes it suspends pc correctly, sometimes not suspends pc or not wakes up pc at all (black screen with no output). i use dual boot with w10 with grub (not uefi) and btrfs for mxlinux. another problem is with language and formats settings – i usually use english language and slovak formats (days, months, currency) while main language and keyboard is still english which does not work because when i change formats on slovak settings, language is changed in slovak. anyway i really appreciate your distro, very good work and i have to tell you it is first distro which suits me out of the box. really thanks!

  13. Inicia rapido el buteo, pero no permite hacer las paraticiones para instalarlo junto a otro sistema opoerativo, intente instalarlo junto a windows 11 y gparted se carga el disco y borra todo, ya me lo cargue dos veces. al momento de preparar el disco para hacer las particiones aparace esta ventana que dice: the backup GPT table is corrupt, but the primary appears OK, so that will be used…putas

  14. Discover non fa aggionamenti :
    Errore:8 bullseye-security Release
    404 Not Found [IP: 80]
    Il repository “ bullseye-security Release” non ha un file Release.
    come posso risolvere?
    Discover does not update :
