[Solved by going to X11]

I am working with my Debian 12 system and suddenly the whole screen goes blank and comes right back. I am not sure what triggers it, it seems to happen when I am exiting a program, I think when It comes back any program I had running is gone now. This is very intermittent and does not happen very often.

Here as a start have a neofetch:

OS: Debian GNU/Linux 12 (bookworm) x86_64

Host: VivoBook_ASUSLaptop S5402ZA_S5402ZA 1.0

Kernel: 6.1.0-11-amd64

Uptime: 12 hours, 2 mins

Packages: 2361 (dpkg)

Shell: bash 5.2.15

Resolution: 2880x1800

DE: Plasma 5.27.5

WM: kwin

WM Theme: plastik

Theme: [Plasma], Breeze [GTK2/3]

Icons: [Plasma], breeze-dark [GTK2/3]

Terminal: konsole

Terminal Font: Hack 19

CPU: 12th Gen Intel i7-12700H (20) @ 4.600GHz

GPU: Intel Alder Lake-P Memory: 3406MiB / 11577MiB

I did journalctl -b - there is a crazy amount of detail in there.

If there is anything specific I can do, please let me know - I am more than a noob, but a lot of the time I only know just enough to be dangerous.

Thanks!

      Thanks for your input, I am not getting up though. In this last instance, I had just closed LibreOffice after editing a document.

    Here is a clue perhaps from Journalctl:

      KDE’s crashing and getting started back up. Due to how Wayland works this will also take down most programs you were running.

      Why is KDE crashing? No idea. You may have better luck with Xorg if you aren’t reliant on any Wayland niceties (proper multiple monitor support, for example)

      edit: https://bugs.kde.org/show_bug.cgi?id=447717 looks like a candidate, but there isn’t enough detail to make sure

        I have rebooted into X11, we will see if there are any more instances.

    I can’t tell you why but it seems like plasma crashed (-> screen black and all opened programs gone) and restarted (-> came back). That’s what I can tell from your description. In your logs you can look for errors from plasma, kwin and maybe something with the gpu driver.

    This can also happen if your GPU isn’t getting enough power. Try unplugging some components to test if the reduction in power draw helps or swapping your PSU out for one with a higher wattage.
