Gentoo:

sys-kernel/gentoo-sources-5.15.59

After suspend to ram - resume several grey rectangles appear on screen.
on x11-drivers/nvidia-drivers-470.129.06: no problem.

Did you enable video memory allocation preservation?

memory allocation preservation were not enabled.
changed /etc/modprobe/nvidia.conf to
…
options nvidia
NVreg_PreserveVideoMemoryAllocations=1
NVreg_TemporaryFilePath=/home/nvidia
…
did a ‘systemctl enable nvidia-suspend.service nvidia-hibernate.service’

now system resumes automatically after suspend, screen is fine now.

You’re running a wayland session so it runs into a bug on suspend

installed https://us.download.nvidia.com/XFree86/Linux-x86_64/515.43.04/NVIDIA-Linux-x86_64-515.43.04.run

ok with this version …
but x11-drivers/nvidia-drivers-515.65.01 is more recent. could it be that there is regression?

8

Yes, an additional regression regarding suspend/resume was also reported for 515.65., depending on hardware used.

OK thanks for your prompt support.
Will wait for the fix of this problem.
I am willing to test on my hardware if you want.
