Hi, I hope I'm putting this in the right place.
I installed arch for the first time, and online recommendations told me to use plasma as a workspace. I am really liking it so far, but I have very bad screen tearing.
I am using an Nvidia GTX680 with PlasmaKDE.
My xorg.conf file is this

EndSectionAs you see, I tried the route to enable triple buffering, but that didn't work.
I've also read to change the vsync settings from the command "kcmshell5 kwincompositing" (or in the settings) to "full screen repaints", but the option changes itself to "re-use screen content" everytime I close the settings.
I've also tried chaging the Rendering backend to openGL, but that also doesn't save when I close the compositor module.
I even followed the WIKI (https://wiki.archlinux.org/index.php/NV … ries_cards) and that didn't work either, it would only show one of my monitors, and tearing persisted.
If you need extra information, I will post it.

Hi, I found the solution.
I installed the nvidia-libgl package instead of the mesa-libgl. It allowed me to set the composition to opengl 3.1 and fixed the screen tearing issue.
