SUMMARY

I have seen the "atomic commit failed: Invalid argument" log message in journalctl countless times previously before a crash, however, I've generally assumed the NVidia drivers were at fault. To narrow down the issues I've now pulled that card out and replaced with an AMD GPU (there is also an inbuilt VGA - it's a server mobo), so that can be ruled out. Most of my stability problems however are still present.

I have just performed a killswitch and rebooted with kernel 6.15 and then logged in to test first thing if screensharing was working properly through a video call in Chromium. Everything proceeded to work, I can share my screen, although I think the mouse was not moving properly over one of the displays, I will retest in a minute to see if reproducible. But I see thousands of lines like the below in the journal and given usually when I see an atomic commit fail it's around something serious that kills the compositor or makes it unusable, am assuming is something that would want to be fixed:

```

```

Not sure whether the driver/kernel graphics stack or KWin would be the culprits here, especially as I have seen other more serious issues with the amdgpu driver (which was suprising me as I thought non-Nvidia cards were generally stable in wayland by now).

Comment 1 stellarpower 2025-07-11 12:18:12 UTC

Note: Realised it was the VGA screen I was sharing at the time and a monitor on the AMD card where I think the mouse was not working properly. However as I saw "DMA" my mind immediately went to the discrete card. I could see the cursor fine within my shared screen from the shared monitor. Afraid I don't remember exactly what happened at the time.

Comment 2 Zamundaaa 2025-10-16 21:48:10 UTC

Hmm, "atomic commit failed" is almost always a driver issue. In your case it's certain because of the traces in the log; you can report this at https://gitlab.freedesktop.org/drm/amd/-/issues

You're not supposed to see "atomic commit failed" warnings on NVidia either, so if you still see them, feel free to create a new bug report with drm debug logs attached (https://invent.kde.org/plasma/kwin/-/wikis/Debugging/Debugging-DRM-issues)
