Test for OpenGL Support
This guide is for Linuxes only. To check if your system is configured for OpenGL correctly, open a console, make sure you are not logged in as root and execute the command:
user@ubuntu:~> glxinfo | grep render
This should produce something like this:
direct rendering: Yes OpenGL renderer string: RADEON 9500 Pro Generic
The OpenGL renderer string will probably look different at your computer, don't panic.
If its written direct rendering: No at your computer, you will have to go over your system configuration again and and look for some good tutorials online to configure it. We can't give you good support, since are not system specialists ourselves. Perhaps there is some help in the installation guide.
