Description Klaasjan Brand 2010-06-02 07:42:45 UTC
Description of problem:

I'm using a laptop (Intel X3100/965 graphics) with an external monitor connected to the VGA output in an extended desktop configuration (no mirroring) and desktop effects.
When unplugging the monitor the laptop panel also goes blank and system seems to be locked up.
If I manually turn the VGA monitor off (xrandr --output VGA1 --off) before unplugging it's not crashing.

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

Fedora 13 as released with default Xorg driver (no xorg.conf)

How reproducible:


Steps to Reproduce:
1. Configure dual-head setup with laptop.
2. Unplug external monitor
Actual results:

Hanging system.

Expected results:

I expect the system to detect the monitor removal and turn off the output by itself.

Additional info:

Laptop is a Dell D830 with Intel 965 graphics using Fedora 13 x86_64.

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 add drm.debug=0x04 to the kernel command line, restart computer, and attach

* your X server config file (/etc/X11/xorg.conf, if available),
* X server log file (/var/log/Xorg.*.log)
* output of the dmesg command, and
* system log (/var/log/messages)

to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

My colleague has similar problem with his laptop and an external monitor, so I will answer those questions:

$ cat /etc/X11/xorg.conf
cat: /etc/X11/xorg.conf: No such file or directory

other files will follow.

This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13.  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bug reports from releases that are no longer maintained.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 '13'.

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 13'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 13 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:

Comment 11 Bug Zapper 2011-06-27 17:19:32 UTC
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 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.
