Trying to switch to dedicated GPU

I've got a lenovo y50-70, which has an integrated Intel HD graphics 4600 and a NVIDIA Geforce GTX 860M. The problem is that the integrated gpu is being used everywhere.

glxinfo -B | grep "OpenGL renderer"

OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 4600 (HSW GT2)

When I check with xrandr:

xrandr --listproviders

Provider 0: id: 0x46 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 3 associated providers: 1 name:Intel
Provider 1: id: 0xa8 cap: 0x5, Source Output, Source Offload crtcs: 0 outputs: 0 associated providers: 1 name:nouveau

Re: Trying to switch to dedicated GPU

If you want to stick with nouveau: https://wiki.archlinux.org/index.php/PR … rs_-_PRIME

If you want more perf via the nvidia drivers: https://wiki.archlinux.org/index.php/PR … er_offload

That might have power saving considerations though, there are a few other options for switching between the two but they are more of the disable the nvidia GPU completely and restart at least the xorg session to actively use it outlined in: https://wiki.archlinux.org/index.php/NVIDIA_Optimus
