I am aware this is an old post....on 16x x86_64 we have labwc, weston or woodland.
The easiest way IMHO to get back to the tty to get back to your libX/Xorg desktop to run startx is
sudo killall <name of desktop> tested for weston, labwc and woodland. If you want to swap to try out a different
wayland compositor and you are seeing a seatd error then at the prompt input
sudo rm -rf /run/seatd.sockand try your launch command again. I am aware there may be other ways, I am trying to show an universal method.
Be aware that a number of applications expect a running dbus eg firefox so weston info suggests
sudo -- seatd -g staff -n /run/seatd.sock & XDG_SESSION_TYPE=wayland dbus-run-session westonbut I use a ~/.local/bin/west that is executable and because seatd is SUID I can get away with
###############
#!/bin/sh
tce-load -i weston xwayland dbus
seatd -g staff -n /run/seatd.sock & XDG_SESSION_TYPE=wayland dbus-run-session weston
############
and my others if you would like to cheat off
~/.local/bin/lab
############
#!/bin/sh
tce-load -i labwc xwayland dbus
export WLR_XWAYLAND=1
# wayland environments
GDK_BACKEND=wayland && export GDK_BACKEND
XDG_SESSION_TYPE=wayland && export XDG_SESSION_TYPE
seatd -g staff -n /run/seatd.sock & dbus-run-session labwc -s lxterminal
###########
~/.local/bin/wood
#############
#!/bin/sh
tce-load -i woodland grim swayimg dbus
seatd-launch dbus-run-session woodland
##############
Obviously you will have more apps in your bootlist...above tce-load command is just to focus my mind that these may not be in my boot list as I swap between Xorg and wayland on a frequent basis
If you want to autostart into one of those compositors I cheated off the idea of GNUser to mod your
~/.profile
comment out the startx line with a # and add line
/home/tc/.local/bin/<wood or lab or west>
change tc to whatever you prefer to use....I am lazy so I still use tc...single user of my PC helps
If that .profile trick kicks you back to the console, as long as your libX/Xorg desktop is loaded startx will launch you back to it. Good Luck
