Title:
17.10 Login To Wayland Fails Unless User Logs Into Unity First
Status in gnome-desktop package in Ubuntu:
Incomplete
Bug description:
After upgrading from 17.04 to 17.10, it's not possible to log into the
default 'Ubuntu' session unless I log into Unity first. If I log into
Unity, immediately log out, then log into Ubuntu, it logs in without
issue.
If I don't log into Unity first, the login attempt to Ubuntu briefly
shows a black screen, then returns immediately to the login prompt.
From suspend or hibernate, I can continue using the Wayland session
without issue through poweroff. If I reboot or shutdown, the first
login needs to be Unity, then I can log out and back to the Ubuntu
session normally.
Attached is some output from syslog showing gnome-session related
errors. I'm not sure if they show the specific error, but they do
appear at the time a first Ubuntu login is attempted.
