Integrated Intel 845GV graphics chip runs rather slowly with OpenGL
 

It runs quite slowly even rendering screen savers, so it occured to me that it may be a problem with using software acceleration instead of hardware acceleration, however I'm not quite sure. So how would I go about configuring OpenGL rendering?

check 'glxinfo', if you have turned on "direct rendering"

if no,
you must add this to your xorg.conf:

Section "DRI"
Mode 0666
EndSection

you have to use driver i915 in kernel to make DRI working.

Ah, it's not on. Now, how would I go about seeing if I'm using driver i915 or how to use it?

And thanks very much for helping me out here :)

if you have compiled i915 into kernel, or as a module.

or if you have kernel from distribution, you must find, if it is.

but i think i915 is only in kernel 2.6.*

Oh, okay. So I'll have to compile the latest kernel.
