Description Samuel Cavazos 2012-04-14 00:15:04 EDT
Description of problem:
Hi, I have an HP Pavilion dm4-1265dx laptop with an intel graphics card and an AOC monitor as a second monitor. There are times when I unplug the monitor from the laptop and Fedora COMPLETELY freezes. I am running Fedora 17 with kernel-3.3.1-5.fc17.x86_64. Seems to happen when I am doing something really important, like having multiple applications open or typing up a LaTeX document.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to reproduce:
1.Plug in second monitor to laptop
2.Have multiple applications open (about 3 or 4)
3. Unplug monitor from laptop
Actual results:
Fedora Freezes completely

Expected results:
Fedora continues to work.

Comment 1 Fedora End Of Life 2013-04-03 11:39:59 EDT
This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)

Is this still an issue with the 3.9 kernels in F19?
Comment 3 Justin M. Forbes 2013-04-23 13:26:48 EDT
This bug is being closed with INSUFFICIENT_DATA as there has not been a
response in 2 weeks.  If you are still experiencing this issue,
please reopen and attach the relevant data from the latest kernel you are
running and any data that might have been requested previously.
