gdm3 won't do anything, "failed to bind" (due to different owners of root dir, /dev and /var)
Affected version
- Debian 10
- GNOME Shell 3.30.2
- XOrg vs. Wayland: not sure
Bug summary
Some kind of corruption caused gdm3 to write 4 gig of 'failed to bind' messages to /var/log/syslog and then not run.
Steps to reproduce
- Switch from gdm3 to lightdm
- Reboot
- Observe that GNOME 'Lock' functionality is missing (expected per gnome-shell#2756 (closed))
- But we want lock, so we reselect gdm3 using : $ sudo dpkg-reconfigure gdm3
- We reboot.
What happened
What happens instead:
- Long pause with a blank screen on boot.
- Then a screen full of booting type info, and system stays on that screen with no activity.
- VTs available. In a VT, I observe gigabytes of messages written to /var/log/syslog. They are almost entirely 'No such file or directory' as in the lines put below in 'Relevant logs'
Write 4 GB of the above into the syslog.
What did you expect to happen
To be able to login to GNOME Shell using gdm3.
Interoperate with gdm3.
