How do I test if OpenGL is installed correctly?

Asked by LEGOManiac

I have a game (BZFlag) which I installed using Synaptic Package Manager. The game runs verrrry slowly on my 3Ghz, dual-core PC.

On a Windows PC the program requires the OPENGL drivers to be installed to get good performance on a 1.2GHz single-core PC so I'm assuming that I need OpenGL installed on the Ubuntu system.

How can I test if OpenGL drivers are installed on my system, and if they aren't, how do I install them?

To test the OpenGL is running , execute this command in Terminal:

 glxinfo | grep direct

When OpenGL is running the message is:

direct rendering: Yes

To install OpenGL drivers, you must install the correct driver for your Video Card (Nvidia, Ati, Intel, ...).

for example, intel video card requires:

xserver-xorg-video-intel

This answered my question on how to get info on OpenGL. I still suspect I have a problem with it, especially after running glxinfo without piping it through grep and viewing the entire output, so I'll save that for another question.

Thanks for the help.
