Screen goes blank

[SAIKIRAN KALLURI]

the screen goes completely blank even though i can hear video playing,the only way i found to solve this is by pressing superkey(windows key)+L and then it turns on when i click space after locking
and now when was opening gnome-tweaks app it suddenly showed a completely white screen and asked me to log out and sign in again which changed nothing when i did logout and logged in
then i performed a restart still didt work and then i open ubuntu on wayland though it did opened iam still facing problems like glitches on display and app list automatically closing by itself and apps closing by themselves.reporting this bug hoping you will fix it.

[Daniel van Vugt (vanvugt)]

I think the nvidia-uvm kernel module is quite happily going out of bounds :)

  UBSAN: array-index-out-of-bounds

What made the screen go black over a minute later might have been amdgpu's fault:

  [ 99.419092] WARNING: CPU: 9 PID: 253 at drivers/gpu/drm/amd/amdgpu/../display/dc/dce/dmub_psr.c:221 dmub_psr_enable+0xf8/0x110 [amdgpu]

Certainly amdgpu looks like the only module actually connected to a display.
