[Bug 496928] [NEW] fast-user-switch-applet hangs and disappears from panel

[Antonio Sánchez]

Public bug reported:

Binary package hint: fast-user-switch-applet

We use fast-user-switch-applet as default method for shutting down
computers in schools. Our users (400.000+) report us that using a single
user of the system at school f-u-s-a disappears (look at the attached
capture) and they can't do a clean shutdown of the computer.
Furthermore, f-u-s-a eats a lot of CPU (50%+).

Our users (students and teachers) doesn't have wnough knowledge of a
linux system for killing the process and restart it so they have to
force shutdown of the computer to continue working.

This behaviour only appears when computers are connected to the net of
the school. The system has the possibility of login against school's
LDAP (OpenLDAP) server. This behaviour appears sometimes in all the
computers of the classroom at the same time.

When this happens you can see at the /var/log/auth.log file the next
lines:

Dec 14 15:30:01 pc236-0 CRON[8544]: pam_unix(cron:session): session opened for user root by (uid=0)

This bug affects Ubuntu 9.04 f-u-s-a default package, but also affects
current version in Karmic 9.10.

Now we are testing with a fast-user-switch-applet backport from karmic in jaunty:
