Today I was trying for the 3rd time to get it to work, using CoRD as an RDP client, but I never got any image back – the client started, I saw the connection being built up, but I never got any image over. Starting rdesktop locally gave me the output I expected.
This gave me the idea of using Microsoft Remote Desktop Connection Client for Mac 2 Public Beta, to see if it might be a problem with the client… and yup, it is.
Seems CoRD 0.4.3 (the current stable) is unable to handle the output of xrdp. I now installed the 0.5 beta 1 which works without any problems.
