Set 3D Effects

Ubuntu7.10 has been installed for a long time. Today, we finally have time to install 3D effect. My video card is ATI radeon Xpress 1100.

It took me 2 hours?

• First, make sure that the driver is correctly installed:

Fglrxinfo

Display: 0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL Renderer string: ATI radeon Xpress Series
OpenGL version string: 2.0.6473 (8.37.6)
The above information indicates that the driver of ATI has been installed.

• Then confirm that the 3D effect is enabled.

Glxinfo | grep direct
Direct rendering: Yes

• First try to open the special effect

First prompt: "The composite extension is not available"

Therefore, set it in ETC/X11/Xorg. conf.

Section "extensions"
Option "composite" "enable"
Endsection

The prompt message is:
"Desktop effects cocould not be enabled"

Other problems

• Find the Forum and find the answer: Install xserver-xgl. After the installation, the special effects can be enabled. In view of the first error message, the changes to the/etc/X11/Xorg. conf file are still saved.

Information:
Xgl Server SETUP changed

The xgl server will now be started automatically next time you login. it is no longer necessary to use any special X session to start xgl, and such sessions will likely fail to work properly. please select a regular session from your session manager next time you log in. to disable xgl autostart for this user, create a file named ~ /.
