I have some issues when using legacy nvidia driver

niko787 · Yesterday 05:42:57

My laptop has old gpu NVIDIA GF108GLM [Quadro 1000M] and i am using the legacy nvidia driver 390.157.

If i don't use this parameter nvidia-drm.modeset=1 in grub i get only one available resolution 640x480? If i use the parameter i get also only one available resolution 1980x1080, which is the native resolution of my laptop. But if i use nouveau driver i can choose from many other resolutions.

Also i have problem with some programs when i use the legacy nvidia driver. For example, with Foliate the covers of the books are blank and some buttons in the program interface are not visible. I don't have this problem when i use nouveau driver.

for OUT in /sys/class/drm/card*; do echo $OUT; edid-decode $OUT/edid; echo "================="; done

You'll need https://archlinux.org/packages/extra/x86_64/v4l-utils/

https://download.nvidia.com/XFree86/Lin … tions.html - look for ModeValidation.
Why would you want to do that?
You can scale the output in various ways.

GTK defaults to vulkan what your GPU/driver will not support but nouvea likely emulates.

The panel advertises only that specific mode, nvidia correctly filters everything else away.
I'd not casually override that w/o a very strong reason.
