Ciao,
Su un PC con Mandriva 2006 avevo una scheda video "Ati ALL-IN-WONDER 128 PRO" che usa il driver "r128" e l'accelerazione video funzionava perfettamente.
Poi ho sostituito la scheda con una nvidia, ho installato il driver 3D, ecc...
Ora ho rimesso la vecchia ati rage 128, ho inserito r128 in modprobe.preload e come driver in xorg.conf, se do un
[root@localhost etc]# lsmod | grep r128
r128 46016 0
drm 60500 1 r128
[root@localhost etc]#
il modulo sembra caricato, ma del 3D nemmeno l'ombra.
glxinfo e glxgears mi dicono rispettivamente
[giorgio@localhost etc]$ glxinfo

Cosa manca (o cosa c'è di troppo) ?
cosa significano questi errori ?
"Error: couldn't find RGB GLX visual
e
"glxgears: Error: couldn't get an RGB, Double-buffered visual."
Suggerimenti ?
Grazie
