3D desktop is an OpenGL program for switching virtual desktops in a seamless 3-dimensional manner on Linux.
Before the configuration, make sure that the compizconfig-settings-manager is installed. Compiz is one of the first compositing window managers for the X Window System that uses 3D graphics hardware to create fast compositing desktop effects for window management.
Update the support list in the compiz script
Edit the script file /usr/bin/compiz-manager,
find the line: WHITELIST="nvidia intel i810 fglrx", and
modify it to be:
WHITELIST="via nvidia intel i810 fglrx".
Enable 3D desktop effects by compiz
Open the compiz config manager from the menu which varies with distributions.
For SLED distributions, open it following Computer -> Control Center -> Desktop Effects,
then switch on the "Enable desktop effects".
For Ubuntu distributions, open it following System -> Preferences -> Apperance, switch on "extra" at the visual effect tab.
Restart X server, the 3D desktop effects will be enabled.
