Public bug reported:

Binary package hint: xorg

I have installed Lucid on E4310 and everything works fine. Now I'm
trying to connect dual FullHD Dell screens via a docking station's DVI
ports. First of all, if I boot the laptop while plugged into the dock,
it just freezes as outlined below. If I first boot it and then plug into
the dock, the following happens: in the System->Preferences->Monitor I
can see 3 panels available: laptop LCD and two Dell monitors(those are
off). However, when I try to disable e4310's panel and enable two Dell
monitors, all screens just go blank and system completely freezes up. No
SSH/Cltr+alt+bkspc/Cltr+alt+F1 possible. Also that is not a kernel panic
as no keyboard lights are blinking.

However everything works if I only enable the laptop's LCD and only one
of the Dell monitors. I Have also tried disabling the laptop panel prior
to enabling the second Dell monitor via lxrandr It allows me to
completely disable the built-in panel(leaving just one DVI Dell running)
but then as soon as I enable the second Dell, eveything just freezes the
same way.

Also after hours of fighting with this, I discovered that the problem
doesn't happen if I boot the liveCD. I'm able to enable both DVI
monitors on it just fine.
