xrandr outputs (corrected)

Oh shit.  Mea maxima culpa :((
I ran it in the wrong terminal (an ssh -X session), so that was indeed my
laptops setting.  Guess I need some coffee.

Yes.

Grown setup.  Initially had a monitor, but I disconnected it once everything
ran fine.  I've considered using an Xvnc only setup, but had not yet started
reading how to do this.  

But to be sure, I have just reassured that it is not an issue of not having a
monitor connected (I found one mention of a similar slowdown when no monitor
was connected).  But even with a real monitor, the remote session stays
sluggish with dropouts, so it seems it's a different issue.  So I think the
issue is still worth investigating, no? (The main issue is already 'solved' by
using the intel driver)

> I mean, if you want to use VNC anyway ...

Sure :)
This is just our standard way here for connecting to the various computers in
the observatory for user support.  And you always use what you're used to (even
if its a hammer for a screw ;^> )

Attached the correct xrandr outputs (sorry again...) - now they indeed differ.
I'll see what I can do with driver options.
