Is OpenGL required ?

Arrrgh, I can't get Mesa to work. How did you do it ? The trouble is I can't find any sensible documentation, not to mention an example.

Basically, all calls to 3D graphics eventually end up in the glx library. Mesa's libglx will do the low-level calculations itself, while the libglx that comes with NVidia drivers or similar basically acts as a front end to your graphic card.

You need to replace the installed libglx files on your system with Mesa's variant, or set your loadpath (LD_LIBRARY_PATH, I think, but not sure) so that Mesa's libglx library is loaded instead of your video driver's libglx.

But... but.. but that sounds like work ! Oh well...

Are you sure you meant mesa and not vesa ?

I tried Kubuntu 6.06 livec/install, and in 'safe graphics' mode it has 'vesa' in xorg.conf . And the funny thing is, glxgears works.

I copied both xorg.conf and lsmod output from livecd for further analysis, but no matter what I do I can't reproduce the effect. (jerky, but spinning glxgears on vesa drivers). Any ideas how to get it to work ?
I already found someone with spare Geforce2MX, but if I could manage without buying it, even for 'symbolic' price...

* nvidea, vesa, nv <--- 2D video drivers. They are completely unrelated to 3D (I suspect in some distant future they will become obsolete, too)
* mesa, fglrx, nvidia <--- 3D opengl libraries/drivers. I have no doubt there is some Debian command to switch to the mesa lib, try google
