Slow graphics, problems with nvidia driver compilation

User Support Hardware Issues
1

Hi everyone,

I’ve just installed the latest Qubes, everything is fine except graphics.

It’s like in slow mode from the Matrix (especially when I drag app windows).

I think that’s because Qubes doesn’t use my GPU (Nvidia 2070 Super). Furthermore, my CPU doesn’t have integrated graphics at all.

I found instructions from the official FAQ about Nvidia drivers compilation and followed them but got an error in the last step.

Previously I’ve enabled rpm-fusion repos, updated the newly created AppVM for the driver compilation and installed yum.

I tried to search any solution for the problem but found nothing.

Also, before the topic creation I tried to search similar problems here, on the forum. Found this thread and link to a Github issue.

I did a step from the issue:

sudo qubes-dom0-update --enablerepo=qubes-dom0-unstable --action=list kernel-qubes-vm

But not sure that it somehow helped.

So, I have several questions.

  1. Is that normal that my GUI is lagging so hard? Some delays, some freezes.

  2. How to make sure that Qubes uses my GPU as fully as possible?

  3. Is everything fine with Nvidia driver?

P.S: I have fast CPU, SSD and RAM. I don’t think that the problem in them.

P.P.S: Nvidia drivers compilation and installation guide link from the official Qubes FAQ (new users are not allowed to have more than 2 links in their topics)

https://github.com/Qubes-Community/Contents/blob/master/docs/configuration/install-nvidia-driver.md

If you need any info just ask for it.

Please help me to resolve the issue. Thank you!

Have you tried ‘Xorg :1 -configure’ and using the xorg.conf with the nouveau driver selected?
