Since I’ve installed Qubes OS (couple of weeks) I’ve been experiencing frequent and random blank screens that require a reboot to get the system back up and running again. Sometimes the display flickers showing blank / bright pink screens, some other times it suddenly just becomes blank.
Other OSs do not have any issue of this kind.
The system load doesn’t seem to make a difference since these episodes happen whether I’m running 10 qubes or just one browser tab. RAM shouldn’t be a problem with 32GB.
I do have an NVIDIA gpu but I don’t care about using it.
I tested with
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset" added to grub settings but the issue still occurs.
Any idea how I could diagnose this problem, or better yet, solve it?
