Wayland
Here's how to run with the
proprietary
Nvidia driver on Wayland:
Prerequisites
To use the Plasma Wayland session:
Use an up-to-date version of Plasma (explicit sync support was implemented in 6.1)
Ensure a reasonably new NVIDIA driver:
minimum supported by KWin is 495.44;
XWayland apps are usable with 555 and newer.
You need to have the Nvidia EGL library installed. It can be a separate package (
libnvidia-egl-wayland1
) or bundled with the driver package (e.g.
nvidia-gl-G06
on openSUSE since 555).
To run XWayland apps without flickering, at least XWayland 24.1 is required.
Use the modesetting driver
Check whether the driver is running in modesetting 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;
is a good starting point.
It is also possible to pass the parameter via module configuration:
echo options nvidia_drm modeset=1 | sudo tee /etc/modprobe.d/nvidia_drm.conf
You need to regenerate the initramfs in case your distribution provides the graphics drivers in initramfs (e.g.
sudo update-initramfs -u
Select “Plasma (Wayland)” from your login manager
Enjoy your beautiful super-fast accelerated Wayland desktop!
