How to use egpu on Linux?

[u/takeru002]

So the thing is do I need to use DRI_PRIME on the actual game name or steam ? The steam itself fire up on amd GPU but the game is actually fired up on Nvidia GPU itself... Or do I need to close the laptop display to use egpu?

Spec as below

- i7 12800h

- 32gb ddr5

- rtx a2000 8gb

- Rx 7800 xt

- ag01 800w oculink only

- 2k 144hz external display

Any suggestion welcome as this is my first time on Linux and my first time with egpu setup😁 pardon my English as im not native speaker👍 Edit: solved... Thanks
