    What is prime-run? Also on my system the same... Looks like you have to add a repository – france1 Sep 20 '21 at 14:43
  • I suppose you mean `optirun` from [bumblebee package](https://packages.ubuntu.com/search?suite=focal&arch=any&mode=exactfilename&searchon=contents&keywords=bin%2Foptirun)... – N0rbert Sep 20 '21 at 20:45

I have the same nvidia driver version and for some reason prime-run command does not exist.

I just solved it by doing the following:

  1. Copy contents of the gist here 
    #!/bin/bash
export __NV_PRIME_RENDER_OFFLOAD=1
export __GLX_VENDOR_LIBRARY_NAME=nvidia
export __VK_LAYER_NV_optimus=NVIDIA_only
export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json
exec "$@"
  2. Create a file ~/bin/prime-run ("~" means your home directory)
  3. Paste the contents there.
  4. Run chmod +x "~/bin/prime-run" to make it executable.

You might want to re-open your terminal or restart your session so your terminal could recognize your ~/bin folder and be able to run prime-run command, that is, if the folder is not already there.

  • Nice workaround. prime-run was part of the proprietary nvidia drivers in the past. I assume that the command has been deprecated, for whatever reason and now removed. – jastram Oct 14 '21 at 06:07
  • I installed nvidia 510.60.02 with runfile and I don't have /usr/share/vulkan/icd.d/nvidia_icd.json. Is the file the same as /etc/vulkan/icd.d/nvidia_icd.json? – Gorgo Apr 13 '22 at 16:45
  • Thanks this worked with 535.54.03 – cyrusbehr Jul 31 '23 at 18:54
