I'm experimenting with wayland.

You can start Gnome with X through startx command. Is there an way to start Gnome with wayland through some command?

I would like to be able to run Gnome/X on my main display. Then switch to display :2 (Ctrl+alt+win+F2/F3) and then run something like:

startWayland

So that I have a seconday desktop with gnome running with wayland.

Is this possible? (A near-alternative is also welcome)

A working solution per Jonas Ådahl a mutter developer:

Usually what I do is switch to a VT and run:

dbus-run-session -- gnome-shell --display-server --wayland

XDG_SESSION_TYPE=wayland dbus-run-session gnome-session

to force firefox and QT applications as well to wayland, in 2019-12-31 they do not respect XDG_SESSION_TYPE=wayland:

MOZ_ENABLE_WAYLAND=1 QT_QPA_PLATFORM=wayland XDG_SESSION_TYPE=wayland dbus-run-session gnome-session

if it should log out the command line session after pressing "logout" in the gnome GUI, add an exec: XDG_SESSION_TYPE=wayland exec dbus-run-session gnome-session

From docs: https://wiki.archlinux.org/index.php/GNOME#Wayland_sessions

Never mind, I found the solution:

gnome-session --session gnome-wayland

[EDIT] This no longer seems to work with recent fedora (24). At the moment I haven't found a solution for this. The only way I get Wayland working these days is to use the gear at login and set the system to log into wayland. If anyone has a solution to this...

Note that the following video drivers do not work with Wayland: nvidia, cirrus, Hi1710.

I discovered this after several days of trying to get Wayland to work with my Nvidia video device until I saw this comment buried in the ArchLinux Wiki for GDM. ArchLinux GDM Wiki

The file that controls this is /usr/lib/udev/rules.d/61-gdm.rules

This script sets /usr/lib/gdm3/gdm-disable-wayland which tells gdm not to show the /usr/share/wayland-sessions on the session menu for these device drivers. (I am using Ubuntu Focal/20.04)

I was able to get Wayland working by uninstalling the nvidia drivers, and although I was pleased to get it working I went back to using the X/Nvidia setup as I preferred the smoother look and performance.
