I have my trusty old dell tower running Centos as a headless server and I VNC into it using screen sharing on mountain lion. All of this works a treat apart from the fact that I have lost the bottom of the Centos desktop in the screen sharing window. I have tried messing with the scaling options in screen sharing and also trying to resize the window but all to no avail. Anybody any ideas? or is there a better app to use for this? Thanks in anticipation.
