Vinagre only gives 800x600 RDC resolution, how to increase?

Using Vinagre on Ubuntu 11.10, when I RDC into a remote Windows XP machine, I only get a 800x600 resolution on the remote display. I can't increase it on the Windows machine, it's stuck at 800x600. Any way to customise?

If I use Terminal Server Client on Ubuntu instead of Vinagre, I can adjust the res. Any way to fix for Vinagre?

I couldn't figure it out either. I'm now using remmina based on this post: http://www.jonathanmoeller.com/screed/?p=3411

remmina has more (or easier to find) settings, right when you set up the connection.

A quick hack:

1. mv /usr/bin/rdesktop /usr/bin/rdesktop.bin

2. create the file /usr/bin/rdesktop to with the contents:

   #!/bin/bash
   
   /usr/bin/rdesktop.bin -g 1024x768 $*

3. chmod 755 /usr/bin/rdesktop

The remote desktop viewer, vinagre, just runs rdesktop, so this in effect sets the default geometry.
