[Gvsig_english] 3D Extension. CALL FOR TESTING

[Benjamin Ducke]

Hi Nicklas,

ATI 3D support under Linux is a long and difficult story...
The only sure thing is that the open source drivers only support
old OpenGL API versions and do not have complete enough 3D
support for most newer chipsets yet.

Personally, I use AMD's latest Catalyst driver from their website
in Ubuntu 10.04 and that works fairly well. But you will have to
be careful when installing it in order not to break your Ubuntu
package management and X11 system updates.

The site phoronix.com has regular coverage of ATI drivers on Linux
and a very useful forum where these things are discussed in detail.

Also, do yourself the favour and disable any 3D desktop effects. 
The interaction of the ATI drivers and Compiz can be problematic.

Best,

Ben
