Public bug reported:
(Not sure if I chose the right package for this bug.)
My dads laptop (Dell Latitude D630) is usually in a docking station, wich is
connected to a big external monitor, while his laptop's screen is shut.
I booted the 11.10 daily live cd (7th of October, 2011) on my dads laptop
(laptop screen shut, external monitor connected via dock) and got a BusyBox...
I tried again, this time with the laptop screen opened as well (still connected
to the external monitor through the dock). I got a mirrored screen, the chosen
resolution wasn't right for either of the monitors. I disabled the laptop's
screen using gnome-control-center and set the resolution right for the external
monitor. I opened the Unity Dash and... everything flickered and went black.
I tried again, once more with the laptop in the dock, connected with the
external monitor, and the laptop's own screen shut. I got the wallpaper, I
heard the login sound, then the last 2 seconds of the login sound kept
repeating. None of the hardware connected to the dock (appart from the screen)
seemed to work. I opened the laptop's screen, wich was empty, and tried to move
the cursor using the trackpad, wich worked. However, no keyboard shutcuts
worked, on neither of the keyboards, not even CTRL+ALT+F1.
I held the power button once more to shut down the laptop, took the laptop out
of the docking station, and booted the CD once more... It worked perfectly!
It's blazing fast, stable, compiz works (wich it didn't with 11.04), ...
The problem seems to be the second screen (or the driver? nouveau in this
case). I'm not sure what this laptop's graphics card is, I only know it's an
NVidia Quadro NVS (I think 135M).
This is a really annoying problem as many people like to connect an external
monitor (eventually through a dock station).
