Public bug reported:
Binary package hint: gdm
The problem is in Ubuntu 10.04 and 10.10. It works in 9.04 (I don't know
in 9.10)
Steps:
1.- Login as user Alice
2.- I want to login as Bob without closing Alice's session:
A) Using the "change user" option in the panel.
B) Pressing Ctrl + Alt + F1
3.- System freezes. I can't do anything (I tried REISUB, Alt +F4, Ctrl + Alt +
Fx). I have to press reboot button.
I have the problem in two different computers with new installations.
In my nephew's computer I installed 10.10 from CD deleting the old 9.04
(removing all hiding directories/files from /home/user). In 9.04 she
could change user. The only new software installed is google chrome.
In my personal computer (pentium 4 2.8 Ghz, 1.5 GB Ram, gigabyte ati
radeon 9250 with defaut ubuntu video driver) when I login after this
error the .xsession-errors.log is:
