Extreme lag on X11

Yesterday at 23:43:30

Hello again guys, I'm currently logged in X11 session on KDE and everything is very laggy. Nouveau driver on nvidia 1060.

I always had better experience with X11 then wayland on my previous systems but I can barely use it now. Is there any tweak or this combo is just unfortunate?

Is there any reason you're not running proprietary nvidia drivers? Nvidia's pascal architecture is in a really weird spot when it comes to support on Linux, afaik nouveau doesn't run at proper clockspeeds for it. But still this shouldn't be the case, maybe it's plasma6 that's this hungry when compositing? Maybe try this: SHIFT + ALT + F12, this should disable it, or you need to look into "plasma-open-settings" and there should be a switch somewhere. I hate to be condescending about proprietary drivers, but for nvidia there's really no free option for proper Linux experience. If nothing helps, please at least temporarly try proprietary drivers, here's how you can install them: https://github.com/korvahannu/arch-nvidia-drivers-installation-guide also you should be looking at nvidia-dkms, not just plain nvidia, with nvidia-dkms you can change the kernel later down the line.

Thanks a lot! After disabling compositing everything is much much smoother.
I was about to install proprietary drivers but will postpone it for now

Resolved, thanks again!
