Title:
Ubuntu 22.04: Display manager resets when trying to change it using
gear icon in login window
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
I would like to select wayland display manager on login screen. But
when I click on the gear icon in login screen, screen resets to
terminal view for a few seconds and black login screen is displayed.
There is no more gear icon, I enter login info and can log into the
session. But the activated display manager is X.org.
Must I wait for some fixes, in order to be able to list different
display managers in login window (the rest on gear icon is normal), or
can I configure the system somehow in order to enable change of
display managers?
less /etc/gdm3/custom.conf
...
[daemon]
# Uncomment the line below to force the login screen to use Xorg
#WaylandEnable=false
WaylandEnable=true
...
echo $XDG_SESSION_TYPE
x11
syslog file attached
