[SOLVED]Dual head setup with hybrid graphics

So my laptop's screen is connected to integrated intel's gpu, and I use external HDMI monitor as my primary, that's connected to nvidia's gpu. I setup my xorg to use Reverse Prime according to this https://us.download.nvidia.com/XFree86/ … ndr14.html but my laptop's screen doesn't enable by default. I can enable it mannualy by running

 xrandr --output eDP-1-1 --auto --right-of HDMI-0 

command. I tried appending it my xinitrc but it doesn't work properly, all I can do is moving my couror around. To make it work again I need to reenable it (xrandr --off and again xrandr --output ...). Screen connected to HDMI works fine.

Outputs:

lspci | grep VGA

00:02.0 VGA compatible controller: Intel Corporation CoffeeLake-H GT2 [UHD Graphics 630]
01:00.0 VGA compatible controller: NVIDIA Corporation GP107M [GeForce GTX 1050 Mobile] (rev a1)

Re: [SOLVED]Dual head setup with hybrid graphics

Don't background the xrandr calls.

xrandr --setprovideroutputsource modesetting NVIDIA-0 
xrandr --output eDP-1-1 --auto --right-of HDMI-0 

note the lack of a &

I'd also replace that static xorg.conf that can break due to a variety of causes with something not as explicit and rigid and use the config mentioned in: https://wiki.archlinux.org/title/NVIDIA … phics_only instead.

Well... I didn't expect my solution to be that simple.  Thanks!
