[Bug 2077254] Re: GUI is killed and returns back to login screen

Tue Aug 20 06:58:26 UTC 2024

Thanks. Those crash reports are from 1-2 years ago so don't look
relevant.

journal.txt seems to show the problem. The system ran out of memory at
Aug 18 10:08:14 but gnome-shell kept running. It was then told to shut
down cleanly by systemd and you can see the clean shutdown a few seconds
later at Aug 18 10:08:20.

So I think this is a systemd feature. It notices something was killed
due to low memory, other processes then struggle to respond to queries
due to low memory, and then the entire session gets shut down cleanly.
There is no crash here, and no gnome-shell bug that I can see.

It's possible systemd decided to log out due to:

Title:
  GNOME session is shut down during OOM and returns back to login screen

Status in systemd package in Ubuntu:
  New

Bug description:
  When too many applications are running and RAM gets full, the OS evicts the most RAM intensive application and kills it. Since anything runs below GNOME in the process hierarchy, GNOME is selected and killed. When it restarts I am back at the login screen.
  This is very annoying since all my work is gone. I guess it is a bug since the RAM intensive application itself should be killed and now my whole desktop environment.
