The display does not support true colour [multiple screens]

I ran into a problem where I was getting the following
error:

ERROR: The display does not support true colour - high
colour support unavailable.

...even though I'm at 16bpp and requested 8bpp.

It turns out the problem was related to the fact that I
have a video card with TV-out, which is my screen #1 @
24bpp, but I'm trying to run on my main CRT (screen #0
@ 16bpp). rdesktop forgets to set the screen number
before calling XGetVisualInfo which results in this error.

I just submitted a patch that fixes this bug:
