Hi Milan, and thanks for the reply. Unfortunately it was of little help
though.

I tried commenting out all traces of the VGA monitor from xorg.conf and
removing the ``Virtual'' line. Afteri that xrandr errored out, crying 
that the virtual screen cannot be bigger than 1440x1440, which it was
automagically set to when there was no specific setting in xorg.conf.

I tried with a configuration that would fit in the given 1440x1440. I
set ``TMDS-1'' normally to 1440x900 and then ``VGA'' to 640x480 below
it. After that I had two problems instead of just one. StumpWM still saw
the whole setup as just one big monitor, and my main screen was garbled.
It showed only random parts of the screen and flickered wildly every
time there was even a small change in the screen (e.g. moving the mouse).

I uncommented the virtual line after that and set up .xsession with my
intended setup, but it didn't work either. About half of the time I was
at the ``normal'' environment where everything was still just one big 
screen, and at other times only the VGA monitor worked while the DVI 
monitor went nuts at every trace of movement.

I'm out of ideas on what could be wrong. Any help would be greatly
appreciated.
