hello, when i install the prime-select, none of the listed files on the github are on the folder and neither the .service files, and when try use prime-select got error and false positive:

TW-WEDC:~ # prime-select nvidia
ERROR: Unable to query GPU information
TW-WEDC:~ # prime-select nvidia
nvidia driver already in use!
TW-WEDC:~ # prime-select intel
ERROR: Unable to query GPU information
TW-WEDC:~ # prime-select intel

Seems your nvidia driver installation failed or is broken meanwhile, so 'nvidia-xconfig --query-gpu-info' fails, so we cannot find the required information for PCI BusID.

For some reason the command apparently still returns 0 (I cannot reproduce this even on a non-nvidia machine), so our check if the command is successful doesn't cover this behaviour.

I can improve the check so it also covers an empty string (assuming it is empty!), but this won't fix your nvidia driver installation of course.

If this helps to fix the behaviour of the script (I doubt!) I can add this patch, but first you should reset your config by running 'prime-select unset' (which doesn't fix your nvidia driver installation of course).

I've got the same error during boot. I think it caused by bbswitch that turns off nvidia card during boot and the "nvidia offload" setting in the intel xorgfile. Edit: resolved without setting bbswitch to keep power state nvidia during boot (edit /etc/modprobe.d/09-nvidia-modprobe-bbswitch-G04.conf, set load and unload to "-1", then do "sudo mkinitrd")

@simopil But then the switch should fail and script should bail out with exit 1. It apparently does not. That's what I don't understand here.

simopil commented 5 years ago

The error for me was during boot and not during switch, so I resolved it with preventing bbswitch to switching off nvidia itself during boot (and before prime-select execution)

sndirsch commented 5 years ago

@simopil OK. If this required a patch against suse-prime, could you do a pull request, please? Thanks!

hello, i did a fresh install and the problem was solved, i found before the fresh install, that the folder /etc/X11/xorg.conf.d was empty, and gave bad perfomance on the nvidia and on the intel, i will close this issue.

sndirsch commented 5 years ago

Ok. Thanks for the update!
