Optimus on Linux is far from perfect however using the native
To be honest, I've tried many things and I'm at a loss here. I'm not a Linux expert, I've been using it for about 4 years as my only operating system.
Since KDE supports
nVidia
drivers most issues I had in the past are mainly resolved except one.
Whenever I run a full screen application, like Kodi
or some Steam
games the position is off, either the screen is centered right in the middle of the 2 screens on exactly 1080p or is rendered showing only the left half on any display.
I think this is due on how I made the multi monitor setup working using xrandr
.
When sddm
initializes it runs the following command:
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --output HDMI-1-1 --mode 1920x1080 --pos 1920x0 --output HDMI-0 --primary --mode 1920x1080 --panning 3840x1080+0+0/0x0+0+0/0/0/-1920/0
It works perfectly however as you might notice the container is 3x1080p as this is due to having 3 screens (all being 1080p), disabling my internal display and using panning I am able to shift the output for 2 monitors right next to each other.
It appears I cannot control full screen behavior, noor in KDE
or by using put
. Playing around in the applications settings I can select which monitor to render it on, but it renders in the center anyways.
To clarify:
xs on monitor left at 1920/2
ys on monitor left at 1080
xe on monitor right at (1920/2)+1920
ye on monitor right at 1080

Wayland
I am willing to give this a try however due to the amount of issues I had with Optimus in the past I am reluctant to try it out because everything is running so smoothly and there is little information about Optimus / Nvidia / Wayland compatibility.
Is there anything I might perhaps I've missed before doing anything as radical as changing a stable display manager for a new one? Or perhaps one simplistic command from the terminal for running applications I missed out completely.
Any help is appreciated.
