My Ubuntu 18.04 is unstable with nouveau (slow and crashes when I open system settings).

So I installed the Nvidia proprietary driver (I tried each one from nvidia-driver-390 to nvidia-driver-470) but at reboot I get only the 640x480 resolution without being able to change it (and the Nvidia control panel is empty).

I tried to purge all the nvidia stuff (sudo apt purge *nvidia*), I deleted xorg.conf and the I tried manually forcing the desired resolution... nothing works.

It used to work (with nvidia-driver-460), then I moved my Ubuntu install to a machine with integrated Intel graphics, when I moved back to the previous machine with the Nvidia GPU this issue appeared.

This is some information about my setup:

$ sudo lshw -C display

Edit: I found that for some reason my system is using llvmpipe somehow related to VMware (that I had installed, but now is not installed anymore).

Any idea?

  • What do you mean exactly by "moving the install"? – Organic Marble Jul 29 '21 at 15:36
  • I installed it on a drive on the PC with the Nvidia GPU, then for a while I used it on a Laptop with Intel integrated graphics, now I'm back on the PC with the Nvidia GPU. – Wizard79 Jul 29 '21 at 15:47
  • That's not specific enough. Did you clone the install and copy it to another computer? Swap the hard drive? Install fresh? – Organic Marble Jul 29 '21 at 15:48
  • To me it was clear that I moved the drive, but what's the difference anyway? – Wizard79 Jul 29 '21 at 15:54
  • Thanks for the info! It might be clear to you, but you are not the one you are asking for help. Keep in mind that everyone here is volunteering their time, and showing attitude is not a good way to get help. – Organic Marble Jul 29 '21 at 15:56
  • is this a install in vmware? Vendor: VMware, Inc. (0xffffffff) – nobody Jul 29 '21 at 16:26
  • @nobody: no, it's not running in a VM (and has never been) – Wizard79 Jul 29 '21 at 16:33

    llvmpipe is part of the Mesa drivers that were used when your hard drive was installed in the machine with Intel graphics. The question is really how to stop using Mesa in favor of Nvidia. This question doesn't have an answer, but it claims to be able to at least temporarily stop Mesa and use Nvidia. https://askubuntu.com/questions/1030471/ubuntu-16-04-mesa-32-bit-libraries-removal – Organic Marble Jul 29 '21 at 21:11
