Gnome-Wayland Desktop Shell Support

With L4T release 32.4.2 NVIDIA supports the Gnome-Wayland windowing system. L4T support for Gnome-Wayland is currently experimental.
This section describes some procedures for using Gnome-Wayland.
To start the windowing system
1. In /etc/systemd/nvuser.sh, change:
GNOME_WAYLAND="0"
To:
GNOME_WAYLAND="1"
2. In /etc/modprobe.d/tegra-udrm.conf, uncomment the line:
#options tegra-udrm modeset=1
(Remove ‘#’ from the start of the line.)
3. In /etc/systemd/nv.sh, change:
DISABLE_MESA_EGL="1"
To:
DISABLE_MESA_EGL="0"
4. In /etc/systemd/system/nvargus-daemon.service, stop the nvargus daemon from being launched on boot by inserting ‘;’ at the beginning of the line:
ExecStart=/usr/sbin/nvargus-daemon
5. Reboot the device. If auto-login is enabled, L4T logs you in to a Wayland session; otherwise it displays a list of available interfaces (e.g. Wayland, command line) and logs you into a session of the type you select.
