Public bug reported:
Binary package hint: xserver-xorg-video-intel
At first I thought this was related to bug #419328, but that bug can be
worked around by disabling compositing features or switching to metacity
away from compiz. This bug is not affected by disabling compiz.
Using the following constants:
Compiz disabled (using metacity)
Appearance visual effects settings set to "None"
Latitude E4310 (which has an Arrandale CPU with built-in intel GPU
I did the following tests:
1a. Plug in external monitor using build-in VGA cable, then start
gnome-display-properties.
Result is that the display freezes, either nothing or some small artefacts are
displayed on the laptop display, nothing is displayed on the external display,
the computer does not respond to any inputs, unplugging the screen does
nothing. The caps-lock light is NOT flashing. The machine must be restarted
using a hard reset.
1b Start gnome-display-properties, plug in external monitor using build-in VGA
cable, then click "detect"
Same result as 1a. Note that the problem only occurs in this instance after
clicking "detect"
2. Start the laptop with the external monitor connected and laptop lid closed.
The computer starts and uses the external monitor as a display as expected.
After opening the lid nothing happens. After opening gnome-display-preferences
and clicking "Detect" the laptop display is not detected. Using the Fn-F8
combination does nothing. The laptop display cannot be detected.
3. Start the laptop with the external monitor connected and laptop lid open.
The machine does not produce any visible signs that it has booted. Nothing is
displayed on either screen and no key combinations (including Ctl-Alt-F1) make
anything come up on either screen.
4. Boot the machine using the Ubuntu amd64 10.04 liveCD, and repeat the
procedure 1a or 1b.
Displays are detected as expected and dual-screen works. Note that this is also
the case if compiz is enabled and full visual effects are switched on.
It appears there has been a regression between 10.04 LiveCD release and
now.
Happy to provide more info as required.
