Comment 2 Ben Skeggs 2013-09-16 20:36:28 EDT
Is this one reproducible?  If so, how do you trigger it?
Comment 3 mshlyn 2013-09-17 12:31:43 EDT
Yes, It is always reproducible.
I tried twice just now. 

How to reproduce:
1, open terminal; su to root;
2, type 'echo OFF > /sys/kernel/debug/vgaswitcheroo/switch'
3, open an avi or mpg file.

the whole computer locks immediately when I double clicked the video file , no any response to keybord or mouse. In fact I waited for more than 30 seconds, so I have to power off it by pressing the power button for some seconds.

I can see a new abrt report like this one after reboot.

Comment 10 Fedora End Of Life 2015-01-09 17:10:58 EST
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Fedora's policy to close all bug reports from releases that are no 
longer maintained.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.
Comment 11 Fedora End Of Life 2015-02-18 08:58:32 EST
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no longer maintained, which means that it will not receive any further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.
