Ubuntu 20.04 using llvmpipe rather than Nvidia Driver

Graphics / Linux Linux

Hey,

I’m currently having issues with getting my Ubuntu system to properly using Nvidia instead of the llvmpipe. Details below:

GPU: GeForce GT 710
Nvidia Driver Version: 460
Linux: 20.04.3

The system recognizes that the GPU is installed (shows up with lshw), but, the following commands show that it is not being recognized for some reason:

nvidia-settings outputs ‘ERROR: Unable to load info from any available system.’
nvidia-smi outputs ‘No devices were found.’
If I use prime-select nvnidia it says that the nvidia profile is already set.
Attempting to launch the NVIDIA X Server Settings app simply creates a blank window.

Safe booting is disabled in BIOS. I have already attempted to uninstall/reinstall Nvidia and have tried versions 470, 460, 450, and 390, and get similar issues with all of them. I have also tried reseating the GPU. Bug report is attached, but please let me know if any other information would be useful for debugging. Any help is appreciated; I’m out of ideas for this.

Please try

  • kernel parameter pci=realloc
  • using a different pcie slot
  • enabling above 4G decoding/large/64bit BARs in bios
  • upgrading bios

Using a different slot did it! Thanks so much!
