I am using the latest daily build of Ubuntu 12.04 on an machine with Asus P5G41T-M motherboard using the built-in graphics (GMA X4500). I have not installed any additional software such as compiz, etc.

I have enabled the default VNC server through the "Desktop Sharing" dialog in settings. When I connect from a Windows 7 machine using RealVNC or TightVNC, the screen doesn't refresh correctly. There are old images left, the new windows do not appear entirely.

I have tried setting disable_xdamage = true in gconf-editor as others recommended for 11.04 and 11.10 but it didn't help.

:) i recommend you to install (gnome-panel) with sudo apt-get install gnome-panel

and then logout, and login with Ubuntu 2d (unity 2d) this will increase performance on VNC connections, because is not using any effects.

Install x11vnc and be sure to select the UltraVNC option when starting the application. It takes care of the problem.
