LOL, true about Super Mario 64 ;-)
Actually, i have an Intel Extreme Graphics 2 Onboard display controller
(a i965G chipset). I had to update kernel to 2.6.9 to get a suitable DRI
driver. After many investigations and thanx to a nice guy on the
internet who had the same motherboard, i managed to have it work and now
glxinfo returns direct rendering ON. Cool.
Next step, testing it --> install tuxracer.
Intel's own driver is old (2004/06) and didn't compile with kernel
126.96.36.199, so i figured:
1) update to 2.6.9 to get a brand new dri driver for the i965G
2) glx.h for Xorg 6.8.1 is old too: 2002, so update to mesa to get a
fresh brand new one with an up to date API, which i did.
But still TR doesn't compile.
Now, could it be possible that the OpenGL API changed that much that the
very type glXGetProcAdressARB doesn't have the same prototype?
(actually, it's a function pointer i think)
TuxRacer is an old game now, more than two years old i believe. Do you
think that it expects a different pointer declaration?
However this makes nonsense as glx.h from Xorg dates from 2002, acually
around the same time as TuxRacer release, so it shouldn't have
Wow, all those improbable theories give me a headache, i'm 15 min from
going to XMas eve party at my parents'... ;-)
I'll have a deepest investigation later.
However, i'm pretty much interested in knowing if other people using
xorg GL managed to have TR work, or is it me just screwing up my install.
