I have Ubuntu 22.04.3 LTS, Gnome 42.9, windowing system X11. I try to use Wayland, but I can't switch to it because I do not have gear icon or cogwheel the sign in button on my on the login (username) page.
My settings:
/etc/gdm3/custom.conf:
# GDM configuration storage
#
# See /usr/share/gdm/gdm.schemas for a list of available options.
[daemon]
# Uncomment the line below to force the login screen to use Xorg
WaylandEnable=true
# Enabling automatic login
# AutomaticLoginEnable = true
# AutomaticLogin = user1
# Enabling timed login
# TimedLoginEnable = true
# TimedLogin = user1
# TimedLoginDelay = 10

[xdmcp]
[chooser]
[debug]
# Uncomment the line below to turn on debugging
# More verbose logs
# Additionally lets the X server dump core if it crashes
#Enable=true

Does it mean that my GPU is not compatybile with wayland?
What should I do ?
