Post-install nvidia prime (and davinci resolve error 999)

Hi everyone,

I have come to have some issue with the installation of nvidia prime on my MSI Vector GP66.

$ prime-run nvidia-settings doesn’t show the prime option.


$prime-run /opt/resolve/bin/resolve.desktop or exec= DRI_PRIME=1.... inside it still show me error 999 (which is a prime error it seams)

I’m humbly asking for some guidance . :sweat_smile:

Or could you point me where I need to seek help?

And thanks :slightly_smiling_face:

well, your driver is running as it should. prime is installed and working. your primary driver is the intel driver (glxinfo is SGI) and running glxinfo with “prime-run” forces to run it with the nvidia card. from this point everything is okay. the malfunction of davinci seems to be a mismatch of davinci with prime. in this case i would suggest to install optimus and drive your nvidia-card as he only primary card.
