Can't run Dota 2 due to GPU isn't discovered properly(my guess)

English Games

1

Hi, i get an error when try to launch a game named Dota 2 on steam. I added
switcherooctl launch -g 1 also to run it directly on my discrete GPU, but the most strange part, is that is may launch and may not. Basically it can throw me this error endlessly while trying to run it, or start from 1 try. And this behaviour may change if some time passes by, for me it seems like random behaviour. Help me debug the issue please!

@emberman Hi set the vulkan device via adding a /etc/environment file, in that file add in your case MESA_VK_DEVICE_SELECT="10de:25ec" save, reboot and check inxi -GSaz and should see the first Vulkan device as the Nvidia GPU.

Hi, thanks for suggestion. I did as you said, but problem still persists. I suppose you meant that this will make my Nvidia GPU a Device-1, correct?

Also i found strange that i have 2 GPUs in this output

Hi
Yes, to force it to be the default device. Looks like it didn’t make a difference… You could try removing libvulkan_intel and see if that makes a difference.

I don’t use steam or the Nvidia rpms on my Tumbleweed setup, so not really sure…

I think i found solution for my problem. I should run steam with these environment variables: DRI_PRIME=10de:25ec DRI_PRIME_DEBUG=1 steam. Then steam properly selects my gpu, without trying to do this automatically

Haha, as if it would fix my problem. Today after PC restart it don’t work anymore. SO it was that “random” working session. Will investigate further.

@emberman kernel updated as I see you were on 6.17.5 earlier? Nvidia driver updated to 580.105.08…
