I cant Change my integrated gpu to optimus/dedicated (Wayland)

I’m using fedora 40 (Wayland)

previously I was using x11 and my GPU driver was fine, but after moving to wayland, my GPU driver really didn’t work.

when I checked using “glxinfo | egrep ‘OpenGL vendor|OpenGL renderer’ it turns out I’m using an integrated gpu, I’ve looked for many ways but haven’t managed to replace it.

I already install nvidia driver + cuda

On another recent thread I read about creating or modifying a file that should solve this problem.

In that thread (I don’t have the link) they mentioned creating or modifying the file /etc/environment with this content.


I just tested that on my laptop with intel + nvidia and I got this in wayland

$ glxinfo | egrep "OpenGL vendor|OpenGL renderer"

Hope this helps.

Thanks, at least my gpu now can work and detect a running process
