Title:
X system crash after user change
Status in “xorg-server” package in Ubuntu:
Expired
Bug description:
I have multiple user account on my netbook. One user (me, uid 1000)
logged in, using "change user" to change to an other account (uid
1001), all ok. After using thunderbird and firefox user 1001 loggs
off. Expect the screen to switch to screen lock prompt for first user
(uid 1000).
But Screen gets black and stays so. No screen change using alt-F1,
crtl-alt-F1, alt-F7, ctrl-alt-F7, alt/alt-ctrl-F8 or alt/alt-ctrl-F9
possible. System looks completely dead, but rebooting using alt-ctrl-
del still works, so doesn't sounds like a kernel lock-up to me, more
like a X mode change or screen change problem.
Will try to reproduce later. Writing this report after the first
reboot, so output of dmesg etc. is not useful.
Might be related to #419410?
