$ lsb_release -rd
Description: Ubuntu 17.10
Release: 17.10
Upgraded from 17.04 today.
Steps to reproduce:
- Start the PC or log out/end session in case it's running with an Xorg
desktop already.
- Attempt to log in, using 'Ubuntu'
Expected to happen:
Desktop appears.
Actually happening:
5 seconds of black screen, then the login screen appears again.
Partial diagnosis:
- Logging in using 'Ubuntu on Xorg' works fine and as expected.
- Extracted a syslog of such a failed attempt, see attached file.
