+1 (Started a duplicate bug so I'll just dump this in here) Upgraded to Hardy 8.04b and I have realised that tsclient is no longer the default vnc client. There is a feature bug in vinagre that developers should know about. In VNC to send special keys (such as ctrl-alt-del) to the remote system, you need to press F8 and select that option in the VNC menu, vinagre does not allow this which is a decline more than an improvement in usability (compared to tsclient).
