I don’t know why but every now and then my display completely freezes, completely except my mouse which is still able to navigate the screen, but can’t interact with anything. No hotkey works, seems that the keyboard freezes too when this happens, except for the one that lets me enable the leds of the pc. I use a msi laptop with hybrid graphics card if that can help
I used to get these random freezes where mouse movements are still possible, but everything else seems to freeze. Haven’t got any recently and it occured very rarely.
However, if I switch to another tty, using ctr + alt + f key and then switch back to the original tty, it seems to fix itself. It might not be related, but worth trying it out.
It’s not that rare for me, it happens at least one time a boot
