Bizarre problem here. I have a ubuntu 10.04 (32bit) desktop that I am trying to VNC into for remote access with my mac. I can vnc fine, and the ubuntu desktop does appear in the screen-sharing window, but no matter what the screen is stuck and unresponsive. When I type things or try to move windows, nothing happens.
Now the really strange part is when I reconnected a display to the ubuntu box, the same windows that I try to move while on my mac are actually moving! So it is getting my keyboard strokes and mouse movement, only on the mac's screen sharing app doesn't indicate this.
I have tried the built-in os x screen sharing app and chicken of the vnc, and both are exhibiting the same problem.
Any ideas?
