I'm currently using Xming (free version) to connect to my remote Ubuntu from my home Windows (I first connect to my remote Ubuntu using SSH and X11 forwarding to localhost).
The performance is, however, terrible: very, very slow, hangups etc. My home connection is not very fast (1.5Mbs down / 160Kbps up), but I don't think this should be a real problem. Is there any other simple, free alternative? Perhaps something that will allow controlling color depth, rate of sync etc.?
Perhaps something that comes integrated in Ubuntu itself? I have root access to my Ubuntu so I can install new stuff if necessary (if needed - please tell me what to install using shell commands, please... I don't have GUI... :))
