[SOLVED]Automatically logout(enter SDDM) sometimes

scarlet · 2024-06-24 14:46:22

I am new to archlinux. These days I find that when I was opening browser , switching between windows, or someting else, the screen turned black and I entered SDDM sometimes(I am logged out).
I cannot figure out what caused it. Like kernel ? KDE ? NVIDIA? Could you please tell me how to locate the error ? Thanks so much.

My devices are listed below.

Most likely the session crashed.
Please don't copy-paste out of the pager (that's the first page of the journal - uselss itc)
If this has happened during the current boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Otherwise … -b -1 … would select the previous boot and you can select older boots by increasing the digit.
