nVidia env flags not working to offload to discrete card?

lf-araujo

Hi all,

For many months I have been offloading sublime text and zoom to the discrete card using a combination of the hybrid profile in nvidia-optimus-profile and the environment variables to activate primus:

env __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia sublime-text.subl

However in recent updates this approach stopped working. Sublime does not load anymore, zoom loads but it does not activate the camera. Anyone else going through this?

Graphics offloading is completely broken in my system for some reason. Logging in in the hybrid profile results in black screen, logging in the intel and nvidia profiles works normally.

Trying to offload with env from the intel profile fails.

Nvidia smi reports an error, however I am pretty sure that happened before:

And nvtop works normally too:

Can anyone from the group report whether offloading is working in your machines?

Thanks.
