Here's how to run with the proprietary Nvidia driver on Wayland:
Prerequisites
To use the Plasma Wayland session:
- 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
To use the Plasma Wayland session with hardware acceleration on XWayland apps, you need:
- Xorg 1.20.12 or later.
- XWayland 21.1.2 or later.
- libxcb 1.1.7 or later.
Use the modesetting driver
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.
Login
- Select "Plasma (wayland)" from your login manager
- Enjoy your beautiful super-fast accelerated wayland desktop!
