I'm using internal VGA these days and I've got a problem:

I can't run any games.

I always get this errors:

--------- [Loading Renderer] ---------

...setting fullscreen mode 3: 1024 768
Using XFree86-VidModeExtension Version 2.2

What is the Vendor of your graphics card? It looks like you might not be using the right (or optimized) driver for it.

You can install "mesa-utils" and run "glxinfo" to get more details about the GLX extension on your machine, but since you seem to be using Ubuntu I'd suggest using the "Additional Drivers" thingy that you can find under "System->Administration->Additional Drivers" to try to let Ubuntu figure out whether you do for example need a binary driver for your card.
