Background
I'm running a dual-monitor setup: primary on Nvidia GPU and secondary on Intel integrated (because it's VGA only) and I'm been having screen tearing issues on my primary and secondary monitor. To fix this I found that I can enable
Code:
ForceCompositionPipeline=On, ForceFullCompositionPipeline=On
in my /etc/X11/xorg.conf settings.
This fixed my screen tearing issues but made my secondary monitor go black with no ability to even cross my mouse pointer over it, ie. not recognized I guess. I fixed this issues by manually adding my secondary monitors PCI BusID to the same xorg.conf file like this:
Code:
Section "Device"
Identifier "intel"
Driver "i915"
BusID "PCI:0:2:0"
Option "AccelMethod" "SNA"
EndSection
Section "Screen"
Identifier "intel"
Device "intel"
EndSection
Problem
My seconday monitor is again working but my primary monitor connected to my Nvidia GPU is black, however I can still move my mouse pointer over to it and my top panel still launch on it even though I can't see it.
