Hi, Torledo.
There's already 2 RDP clients installed. From a terminal :
rdesktop servername -g 800x450
or
krdc
I'll need to check the -g switch options on the rdesktop command though as I don't have one with me at the moment, but that switch sets the screen size. When I've tried krdc it could show the server window, but mouse and keyboard didn't work. I didn't persue it thought because rdesktop worked without problems.
Regards
Rich
