Running Nvidia Wayland

Ensure that you are using Plasma 5.20.2 or later.
You need a very up-to-date Qt. Make sure you have >= Qt5.15.0 or 4bd13402f0293e85b8dfdf92254e250ac28094c7 cherry-picked.
Make sure to have the Nvidia egl library installed. For example on Ubuntu and Neon the relevant package is called libnvidia-egl-wayland1

Check our driver is running in modesettings mode

cat /sys/module/nvidia_drm/parameters/modeset

It should print "Y"

If not, modify your kernel command line and add the line nvidia-drm.modeset=1. Search for "kernel parameters" in your distribution https://wiki.archlinux.org/index.php/Kernel_parameters is a good starting point

-=== Tell kwin to run with EGLStreams. ===
-You should set the environment variable "KWIN_DRM_USE_EGL_STREAMS=1"
-The easiest place is to add a file <code>/etc/profile.d/kwin.sh</code>  with the line
-<code>export KWIN_DRM_USE_EGL_STREAMS=1</code>
-Verify this is working with the command line tool <code>env</code> after rebooting.
