Red Hat Bugzilla – Bug 448321
x freezes while user switching
Last modified: 2009-07-14 13:42:18 EDT
Description of problem:
This is on a Dell Latitude D820 with an intel 945GM graphics card. While trying
to switch between two logged in users (using the user switch applet) X freezes
while showing a screen full of weird colors.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Log in as user A
2. Use the user switch applet to switch to another user.
3. When at GDM log in as user B.
4. From use B use the user switch applet to switch back to user A.
5. X freezes with a colorful screen.
Should be able to switch back and forth between logged in users without problems.
Thanks for the bug report. We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.
Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.
Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.

xorg log from crash
I am experiencing this bug as well. It will happen whether or not I have an
xorg.conf. The only thing I have found as a work around is to add
Option "NoAccel" "True"
in the Device section for my video card.

I can also confirm that running X with the NoAccel option makes user switching work.
I'm on Fedora 10 and experiencing this problem. It actually doesn't show a screen full of weird colors, but it does freeze just before displaying the list of users who I could login as.
Confirm for Fedora 10. Choosing "Switch user" either in fast-user-switch applet or screensaver leads to complete screen lock up. Neither Ctrl-Alt-Backspace, nor Ctrl_alt-Del, nor pressing Power button works.

This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '9'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 11 crashes sometimes. Or rather, after trying to switch user several times.
No xorg.conf here.
I can use CTRL+F1 to switch to the first user, CTRL+F7 for the second user and CTRL+F8 takes me to the frozen would-be login display.
BTW - I also experienced this problem with F10 before upgrading.
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
