i just installed rdesktop and when i ran it from the command line, i got

"Autoselected keyboard map en-us"

and then the GUI loaded. now, when i installed, the app manager told me that rdesktop was not installed because of an issue with ncurses-bin. that didnt seem to be the case, but i digress.

it may be that you have to reflash and try over. i hope thats not the case, but it may be an inevitability.
