Getting OpenGL to work under Ubuntu

Question

I have an Intel graphics card, of which I can't tell whether or not it's being recognized. When I go through GUI to the System Info section, it states that my graphics card is unknown. Despite this, my lspci displays the graphics card perfectly fine.

Question

Is there any way to get OpenGL working correctly on Ubuntu 11.10, or, if this isn't possible (due to my graphics card), would there be any other distros recommended as far as getting this work?

Solution 1

Just because system settings doesn't correctly report your graphics card, doesn't mean it's operating incorrectly. I'm not sure what you mean by 'Getting OpenGL to work', but I'm guessing you mean Verifying accelerated OpenGL?

The two major components of basic acceleration are Xv, and GLX Direct Rendering. Xv does Hardware Video Overlay, and GLX Direct Rendering does OpenGL via Graphics Hardware.

Use glxinfo to check for GLX Direct Rendering, glxinfo is installed via

sudo apt-get install  mesa-utils

Run this command to get your direct rendering status, it will be a yes or no answer.

glxinfo  | grep rendering

Use xvinfo to check for Video Overlay. Make sure x11-utils package is installed.

sudo apt-get install x11-utils

Run this command to check for Video Overlay, should be a long listing, not an error.

xvinfo

This is just the basics, it doesn't verify the new HD video extensions. It should however, tell you if acceleration is even working.

Solution 2

According to the official Intel Linux Graphics Drivers website Linux should support Intel® HD Graphics P3000 included in the Intel C200 Series Chipset Family out of the box.

The cause of your problem is according to the information provided by Intel that Intel® HD Graphics P3000 is only available with select Intel Xeon processor E3-1200 SKUs. So please check up with Intel, whether your specific system is actually OpenGL-capable. I can't answer that question from the sparse information provided by lspci.
