I recently upgraded from 11.10 Oneiric to 12.04.3 Precise and find that when I connect to the machine over VNC (UltraVNC on Win 7) I cannot make the Unity Launcher unhide (using the mouse). Previously it was a little fiddly but would work eventually; now it doesnt work at all. Neither does UltraVNCs Send Ctrl+Esc button Id expect this to open the Dash.
I am running Ultravnc server in windows 7. But when I connect with vnc viewer. The quality of the vnc is low. The image is with small square. So I have tried to find way to tune the image quality. However, I cannot figure out how to make the quality better in Ultravnc server. Please help. Thanks.
