Hi,
the docking station work well except one situation. If I get my
laptop
FROM the docking station, the screen is black. System work well, with
ALT-F1 the console work. But the X-Server don't refresh the screen.
I don't know the specifics of your System but, years ago, I used a
Laptop with a Docking Station, complete with external Keyboard, Mouse
and Display. (Don't recall make and model, but it was marketed as an
alternative to a separate Desktop and Tower). My issue, was that the
Video Chip in the Docking Station was, enough different from the one,
driving the Laptop Screen to need, not only different Drivers, but
different sections in xorg.conf.
It worked for me to "Hot Plug" it into the Dock, and I could use both
monitors as separate Displays. But I encountered something like your
symptom, if I "Hot Unplugged" it. Something about Adding features
being okay, but taking them away giving "hilarious" Syslog Messages
and, in my case, only allowing access to it via ssh.
One diagnostic tool for me, was that lspci gave different results, in
the Dock and outside of it.
So I made a habit of shutting it down, before removing it from the Dock.
