I alluded to the issues here in this thread.
Multiple times, user A is logged in, steps away. When the session “locks”, there ultimately is no ability for another person to log in ever.
- No one is logged in to console.
- User A moves mouse and logs in via GDM. User A walks away, screen locks.
- User C (who actually was the first user installed) moves mouse, enters password via GDM and is presented with an odd screen saver graphic. The mouse moves but there is limited GUI. Pressing “pause” seems to log user C out.
- Fetched user A to unlock screen, gets logged in to expected desktop. Use mouse to log out of their session.
- Presented with expected GDM login. User C logs in and expected desktop presents.
- Mouse and keyboard are not responsive. Moved mouse to another USB port to see if the change brings functionality back.
- ssh in from another computer, su, issue
shutdown -h nowcommand.
- Computer does not complete shutdown, has non-blinking underline cursor on console.
- To have console again, had to hold power button until computer shutdown.
One workaround I can dream up would be to force log out instead of screen lock, but I have no idea how to hack that … or if there’s something else I can do instead.
