Beryl Su Vecchio PC

[KaZaA]

Salve a tutti! Sono dietro ad installare AIGLX + Beryl su un vecchio PC che usa la mia famiglia. Sono arrivato ad un buon punto, AIGLX abilitato, Direct Rendering abilitato ed estensione Composita abilitata. Quando provo però ad avviare Beryl, mi viene fuori questo errore:

Non sputatemi in faccia, ma come avrete già capito dal glxinfo, la scheda video su cui stò cercando di far funzionare Beryl è una vetusta 3DFX Voodoo 3 3000 AGP VVoVe: VVoVe:

Su un Wiki di Beryl, ho letto che la Voodoo 3 è supportata, quindi teoricamente dovrei essere in grado di far funzionare stò benedetto desktop composito...idee?

[KaZaA]

Allora...per abilitare il Double-Buffering GL è necessario impostare la profondità di colore a 24Bit nello xorg.conf...ma le 3DFX Voodoo oltre i 16 Bit non abilitano più l'accelerzione grafica (è proprio una limitazione hardware della GPU).
Senza DRI Beryl parte, ma si vede tutto bianco e va tutto molto lento (ovviamente). Idee?
