Plasma/Wayland/Nvidia

Running Nvidia Wayland

Step 0:

• You need a very up-to-date Qt. Make sure you have > Qt5.15.0 or 4bd13402f0293e85b8dfdf92254e250ac28094c7 cherry-picked.

Step 1

• Check our driver is running in modesettings mode

"cat /sys/module/nvidia_drm/parameters/modeset"

It should print "Y"

If so, you can skip step 2

Step 2:

• Modify your kernel command line.

Search for "kernel parameters" in your distribution and add the line "nvidia-drm.modeset=1" https://wiki.archlinux.org/index.php/Kernel_parameters is a good starting point

Step 3: 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 /etc/profile.d/kwin.sh with the line export KWIN_DRM_USE_EGL_STREAMS=1

Verify this is working with the command line tool "env" after rebooting.

Step 4: Select "Plasma (wayland)" from your login manager

Step 5: You should be greeter with a beautiful super-fast accelerated wayland desktop!
