[solved] Turn of dedicated GPU on Desktop PC

schtiehve · 2017-06-11 12:30:26

I have a Game (running on wine) that I didn't have any problems on running my integrated GPU (Intel HD530) but since I got my dedicated GPU (AMD RX470) when I launch the Game and load a savegame (or start a new game for that matter) i can move a little and then the output freezes. I can still move around and interact with everything (based on the sounds) but i cant see what's happening. I verfied that the problem is the dGPU because as soon as I physically removed the GPU the Game worked flawlessly.

If somebody has an idea for a Fix I'd be happy to hear it but honestly I would be content with a workaround (i.e. a way of switching from the dGPU to the iGPU that doesn't require me to physically remove the GPU.

I looked around and all I found was for Laptops with Hybrid graphics I don't really know how they apply to Desktop Hardware.

You should provide more informations, notably what "game" and outputs of

lspci
loginctl session-status
glxinfo

w/ the gpu in place - last command assuming this is a GL game and not freecell.
Also check if you've problems w/ other GL clients, first and foremost "glxgears" and random others, be it tuxkart or warsow or sauerbraten (depending on your gaming preferences ;-)

Where is your monitor connected?

The Game is Gothic 1/2.

Other Games do work. Steam Games, other Games on Wine, Supertuxkart

@ROOKIE: My Monitor is connected to my GPU but it has mutltiple Inputs and can be connected to my Mobo as well

loginctl session-status

I'm mostly curious on whether there's a compositor/compositing WM (and whether that operates on GL and can be deactivated ;-)

I assume that by "My Monitor is connected to my GPU" you mean it is connected to the discrete card. I'm not sure what X does in that case but I suppose it will assume the discrete card is the primary card and as such everything will try to use it. The output of glxinfo you posted seems to confirm that.

Have you tried to connect your monitor to the motherboard to make use of the iGPU for most tasks and using dri prime when you want to use the discrete card?

Thank you guys. By trying around a bit I found out that I can enable the Internal GPU as well as the dGPU by changing a setting in the BIOS. Then I activated PRIME by following https://wiki.archlinux.org/index.php/PRIME now I can run the Applications I want to run on the GPU with DRI_PRIME=1.

Arch Linux
