Hello folks,
I wonder if any of you who is using an AMD GPU (especially newer ones)
has encountered the same problem as I do.
My problem is that sometimes the screen just freezes entirely, and I
have to switch to another TTY and back in order to get it unstuck. But
the same freeze will usually happen again after I get the things
unstuck. Restart my PC doesn't fix the problem.
Here are some informations about my system:
- CPU/GPU: AMD Ryzen 7 PRO 7840U w/ Radeon 780M Graphics
- vainfo output: in attachment `vainfo-output`
- system log: in attachment `sys-log`
I do find a workaround online somewhere, that is to set
`amdgpu.vm_update_mode=3` kernel parameter, and it seems to fix the problem.
I never have this kind of problem on Linux distros I used before Debian
(Void, OpenSUSE,) so if anyone has some idea why this happens, please
give me some advice, thanks!
