Ciao, ho un problema con la scheda integrata del computer al lavoro....
Ho una intel 9xx con dri opensource... altri software opengl funzionanano (piano ma funzionano) e soprattutto nel computer di un mio collega che usa uindos, tremolous gira dignitosamente... 
c'e' qualcuno che e' riuscito a farlo funzionare con la suddetta scheda sotto x ?
allego il glxinfo e l'output in console di tremulous....

Potresti provare a vedere in xorg.conf (o nella conf di XFree86) per vedere se ti si carica il DRI; in extremis potresti provare a ricompilare tremulous (io ad es. l'ho fatto per applicare un patch di sicurezza).
Ciao!!
Leggendo qua e la' su internet ho scoperto che alcuni programmi (tipo il motore di quake) aprono dinamicamente via dlopen la libGL.so invece che linkarla a compile time e in questo modo il linker non tira su tutti i simboli, la soluzione e' stata via LD_PRELOAD=/usr/lib/libGL.so
mediante questa variabile d'ambiente invece si accende il debug sulle libGL...
