There are several issues with that notebook. Connecting an external monitor to the nvidia gpu triggers errors from the display engine, a suspend/resume always ends with an Xid 62 for unclear reasons. Furthermore, the intel i915 driver, which drives the internal display oopses on boot. So it’s currently unclear to me which gpu/driver is causing the black screen on resume.
The i915 driver has a known issue on 12th gen cpus but the fix for that will only be in the 6.3 kernel which is not released yet.
Than I wait just a little more for the new release and try that kernel. I can always change back, if it doesn’t work.
I’ll report back when I test this solution.
And I can tell, that the X.Org (open source) driver works a little bit better. It has the same problem, but shows for a second the mouse and the login screen before it all goes to black. Then I just restart the PC with REISUB gentle restart.
