3D Desktop

Enabling Desktop Effects

To enable desktop effects you need a graphics adapter capable of providing 3D support
and the graphics driver that Linux uses to operate the graphics adapter. This driver must
be able to handle OpenGL (or 3D) requests from the Linux kernel. If your configuration
is compatible with desktop effects it will be enabled by default. If your configuration
does not support desktop effects you will be warned upon activation.

To enable or disable desktop effects follow these steps:

1

Click Computer > Control Center.

2

Click Desktop Effects in the Look and Feel group.
