Red Hat Bugzilla – Bug 808631
Using gnome-shell under an xguest account results in visual artifacts
Last modified: 2013-02-13 09:15:17 EST
Description of problem:
Upon logging into an xguest account and attempting to access one of the menus or other graphics accelerated portions of GNOME, the menus, popups, etc. begin to flicker.
Version-Release number of selected component (if applicable):
Install an xguest acccount and login to it. Then attempt to use any portion of gnome-shell that uses 3d acceleration.
Steps to Reproduce:
2.Log in to xguest account
3.Attempt to use Activities, status menu, etc.
Menus flicker rapidly on the screen.
Menu pops up and remains present and unaltered until the user alters the menu
Is this SELinux issue?
$ setenforce 0
Does it work then?
It is unclear as to what the exact cause is.
It only takes place on the xguest account. You can not turn off SELinux and still use xguest.
If policycoreutils is too broad, the bug could be assigned to xguest specifically. This does not occur on other accounts on the system.
I know that setsebool -P allow_xguest_exec_content on fixes the crash that is explained in the linked bug, so that leads me to believe that there may be other SELinux issues causing the problem.
This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. 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bug reports from releases that are no longer maintained.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 '16'.
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 16'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 16 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, you are encouraged to click on
"Clone This Bug" and open it against that version of Fedora.
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 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 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.
