Hi, first time posting here, long time user of krita and happy supporter to the development fond! Big thanks to the developers for an amazing program!

At home I run Ubuntu on my work station, and I recently updated to Ubuntu 26.04 and unfortunately Krita has stopped working with my tablet, there is simply no response.

The tablet works great with other programs. I have found some help online with people who seemed to have the same issue but got it working. But I cannot seem to get it working regardless.

I am running krita from the appimage, I am not really an experienced linux user, but I tried forcing wayland (I will be honest, not entirely sure what wayland is) as described in the link above, but get this error:

arning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
qt.qpa.plugin: Could not find the Qt platform plugin “wayland” in “”
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.

I tried installing the qt stuff, but no luck.

I also found a reddit post with same poblem:

https://www.reddit.com/r/linuxquestions/comments/1t2lkk9/krita_pen_tablet_issue_with_ubuntu_2604_resolute/

Sorry in advance if I posted this the wrong place, or wrong forum even. Any help would be much appreciated.

Out of curiosity, what does Xwayland -version says?

3

I get this:

The X.Org Foundation Xwayland Version 24.1.10 (12401010)
X Protocol Version 11, Revision 0
xwayland 24.1.10 ( Debian -- User Support )

I also want to clearify, that the table’s touch features work, it is just the pen that does not work with krita, unfortunately the pen is all I use.

Yup, Xwayland 24.1.10 is faulty, it fixed a few important things but also brought this bug, try updating or downgrading it

Hi Crimson,

Thanks for taking the time to help. It would be amazing if this is the fix. If it is not too much to ask, how do I update or downgrade it? Like I said, not an experienced linux user, and I am not getting good search result on how to update it.

I found this solution, does it sound right?

But you mention xwayland and this sounds like just wayland.

There should be a fixed version/update on the app store atp, in case it’s not, gotta double check that cuz I’m unsure if the downgrade command is similar (it has been a long while since I last used an Ubuntu based distro)

The package is called xorg-x11-server-Xwayland, so we can begin there

7

No worries, unfortunately the apt-get gives me: “E: Invalid operation xorg-x11-server-Xwayland”

8

Nice timing, I found this article, looks simple enough to follow

Again, thank you so much for your time!

I followed the guide, and unfortunately, it does not look like there are any option, i ran “sudo apt-cache policy xwayland”

xwayland:
Installed: 2:24.1.10-1
Candidate: 2:24.1.10-1
Version table:
*** 2:24.1.10-1 500
500 Index of /ubuntu resolute/main amd64 Packages
100 /var/lib/dpkg/status

  • any chance we could be looking in the wrong place for the error in krita?

Awn man, sorry to hear that

Possible, although that one package did cause trouble around systems, and according to your description, seems to be the case once again (which, again, it’s weird that you didn’t get the updated package yet)
Maybe we could wait for someone more acquainted with Ubuntu, so they can offer a better help/solution to it

11

No worries, I really appreciate your help. I will keep digging myself, maybe I stumble on something.

Just wanted to add another user with the same issue:

https://www.reddit.com/r/krita/comments/1tees14/help_please_for_linuxubuntu_2604/

Edit: is there a place I can report this bug officially?

Edit 2: found this too:

https://www.reddit.com/r/linuxquestions/comments/1t2lkk9/krita_pen_tablet_issue_with_ubuntu_2604_resolute/

13

found this thanks to a friendly user:

Unfortunately I do not seem able to downgrade to the mentioned version, unless I am simply doing it wrong but I have been trying with:

sudo apt install xwayland=xwayland-24.1.9 and various version of this but I get:

Package xwayland is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

14

I have a solution, the analysis was right, xwayland was the issue, for some reason I cannot download it via “sudo apt-get install xwayland=2:24.1.9-1”

But i managed to download the .deb and run it with “sudo dpkg -i xwayland_24.1.9-1_amd64.deb”

Krita works now. Now I just hope it didn’t break something else.
