X Test Day: Video breaks when secondary monitor is connected
Last modified: 2015-02-17 09:28:44 EST
Description of problem:
When secondary monitor (Samsung SyncMaster 2243 through VGA cable) is connected to Dell Latitute D620 laptop, the video breaks - it starts showing artifacts / garbled output, and the desktop become unusable. The problem persist even after disconnection of the external monitor, X restart is needed. I encounter this problem during X Test Week (nouveau).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Start gnome-shell
2. Connect external monitor
Video works normally.
Quadro NVS 110M video card, smolt profile for the machine: http://www.smolts.org/client/show/pub_c7d88856-a286-4c4d-a41f-22c5971e6105
It works correctly if X is restarted with monitor connected

yup, it doesn't. It seems to be OK on the first look, but the video break on firefox maximization.

Unless I'm missing something, I don't see how this qualifies as a blocker for F18. It sounds like the laptop's display functions correctly when used by itself but issues appear if a secondary monitor is connected.
If I'm missing something here, please list the F18 release criterion (alpha, beta or final) that this bug violates or at least a justification why this bug should block the release of F18.
agreed with tflink, single system bugs are rarely blockers, and *certainly* multi-head only single-system bugs aren't.
Agreed, it's definitely bug but related to custom combination of HW, system boots, desktop is usable on the primary head. And restarting X fixes the issue partially.
-1 blocker, jreznik's comment is spot on.
I count -5 blocker. Moving to rejected
Jaro, are you able to reproduce it on latest Fedora 18 or 19?
I think the problem is related to the bug 924385. The effect is nearly the same, but triggered by connection of secondary monitor. It seems to be reproducible only in the gnome-shell. It works correctly in Xfce.
This message is a notice that Fedora 19 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 19. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.
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.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 19 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 change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
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.
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 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. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
