[ubuntu-it] Xlib: extension "GLX" missing on display ":0.0".

Dom 22 Ott 2006 16:54:50 BST

Cari utenti ubuntu...
ho una scheda video nVidia Corporation NV17 [GeForce4 420 Go] (rev a3)
ho installato, molto tempo fa a dire il vero, il driver nvidia preso dal
loro sito... 
poi ho configurato xorg.conf 
e adesso, come si vede anche dallo splash screen di avvio di nvidia, il
driver viene caricato sembra correttamente...
funziona anche il twinview

il problema è che volevo far girare tuxraces per provare l'accelerazione
3d (visto che ho dei problemi con un altro software che usa grafica 3d e
sospettavo problemi di stistema) ma ottengo questo risultato:
