Il mio case ospita da poco una Matrox G400/450 PCI (non chiedetemi quale è delle due :p ) con supporto a 4 schermi, ma non riesco a far funzionare l'accellerazione 3D. Se provo a lanciare glxgears ricevo questo output:
$ glxgears
libGL warning: 3D driver returned no fbconfigs.
libGL error: InitDriver failed
libGL error: reverting to (slow) indirect rendering
1244 frames in 5.2 seconds = 239.069 FPS
Questo è il mio xorg.conf:
Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
Option "XkbLayout" "it"
EndSection
Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
EndSection
Section "Device"
Identifier "Matrox Graphics, Inc. MGA G400/G450"
Driver "mga"
BusID "PCI:2:0:0"
Option "OldDmaInit" "True"
EndSection
Section "Monitor"
Identifier "Configured Monitor"
Option "DPMS"
HorizSync 30-65
VertRefresh 50-75
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
DefaultDepth 24
SubSection "Display"
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
EndSection
Senza Option "OldDmaInit" "True" il server grafico si caricava senza problemi ma non si vedeva niente.
La distro è ovviamente debian sid amd64.
