NVIDIA GPU offload

hey guys, so I have recently installed Arch on my laptop, which is quite recent (RTX 3070 and i7 11800H).

I am running KDE and the proprietary NVIDIA drivers along with i915 for my i7.
I somehow noticed just recently that I was only using the discrete GPU, because I set the discrete graphics options in my BIOS.

When I noticed this mistake i corrected it, only to get stuck during system-udevd.  I tried looking at PRIME, which of course is already installed along with the drivers,
I updated my Xorg config  (it was missing a device section for my i7), i tried setting the provider offload sink on the integrated graphics from xrandr, but nothing worked, it would still get stuck on boot.
lastly I tried optimus-manager, but that just made me blackscreen on boot. any help? The battery life is incredibly short like this.
thanks in advance

Re: NVIDIA GPU offload

Remove everything you've tried PRIME is enabled by default and doesn't need any active adjustment from your part. You only need to install nvidia-prime and use prime-run to run clients like

prime-run glxinfo -B

If the subsequent reboot works (.... or not) post the xorg log that got likely generated and

sudo journalctl -b

https://wiki.archlinux.org/title/List_o … n_services I'm assuming you're able to get to a terminal with Ctrl+Alt+F2 and so forth?

thanks sm for the reply
the issue somehow seems to have fixed itself. I have done nothing but turn the PC on and off for normal use and it is gone. Have a good evening!

Re: NVIDIA GPU offload

If it's intermittent it might happen again and in that case might point to the modesetting race: https://wiki.archlinux.org/title/Kernel … _KMS_start and enabling modesetting on the  nvidia driver: https://wiki.archlinux.org/title/NVIDIA … de_setting keep that in mind should the issue turn up again (on "specialty" here is that you should add both all the nvidia modules as well as the i915 module for the intel card there to the mkinitcpio config.

In any case if it's solved, please mark it as such by editing the title in your first post and appending [SOLVED] or so.
