Gnome-Wayland Desktop Shell Support#

Starting with NVIDIA DriveOS™ 7.0.2.0, Gnome-Wayland desktop shell support is only available for dev_nsr.

To enable experimental Gnome-Wayland desktop shell support:

  1. Install gdm3, mutter, and their dependencies:

sudo apt update
sudo apt install -y gdm3 mutter adwaita-icon-theme-full
sudo apt install -y --reinstall libdrm2 ubuntu-session

  1. Repair the broken drm-nvdc soft link and rename the Ubuntu session file:

sudo ln -sf /usr/lib/libdrm.so.2 /usr/lib/aarch64-
linux-gnu/libdrm.so.2
sudo mv /usr/share/wayland-sessions/ubuntu-wayland.desktop
/usr/share/wayland-sessions/ubuntu.desktop

  1. Add the gdm daemon to the video group:

sudo usermod -a -G video gdm

  1. Configure gdm to use Wayland by setting the following flag in the [daemon] section of /etc/gdm3/custom.conf:

[daemon]
WaylandEnable=true

  1. Load the nvidia-drm kernel module:

sudo modprobe nvidia-drm modeset=1

  1. Start gdm:

sudo systemctl start gdm3.service

  1. Log in and verify the Wayland backend is running:

ps -e | grep wayland

  1. Reboot and repeat step 7 to verify the Wayland backend auto-started successfully.
