Bug Description

Binary package hint: xorg

I have a Sony Vaio with Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) and 1280x800 screen.

I connect a projector and after that I type "xrandr --auto" in a terminal window. Then I get my desktop from the internal screen also on the projector. As the projector has only a resolution of 1024x768 the internal screen also switches to this resolution.

Then I unplug the projector. This makes the desktop on the screen disappear. On the screen appears a white area in 4:3 ratio and maximum size (so there are black borders on the left and on the right. I can get my desktop back by pressing Fn+F7 one or more times, but then the GNOME panel stays in the 1024x768 format and does not get back to the screen's 1280x800 default resolution.

Till,

Upstream wishes additional information to solve your bug. Set the following in the Driver section of your xorg.conf:

    Option "Modedebug" "True"

They also want register dumps. To collect these, run two test cases:

1) Plug in projector (where laptop is working) and collect `sudo intel_reg_dumper > dump_good.txt`. Attach both that and your Xorg.0.log to the upstream bug.

2) Unplug projector (where laptop does not work), and collect `sudo intel_reg_dumper > dump_broken.txt`. Attach both that and your Xorg.0.log to the upstream bug.

Bryce, I will do this tomorrow when I am back to the conference room so that I can do the test with the projector.
