Ho tentato di installare Fglrx e facendo #lsmod |less appare, ma qualcosa non va:

/var/log/Xorg.0.log

(WW) R128(0): Can't determine panel dimensions, and none specified.Disabling programming of FP registers.
(EE) R128(0): No DFP detected
(!!) R128(0): For information on using the multimedia capabilities of this adapter, please see http://gatos.sf.net.
(EE) R128(0): [dri] DRIScreenInit failed. Disabling DRI.
(WW) R128(0): Direct rendering disabled
(EE) AIGLX: Screen 0 is not DRI capable

Inoltre:

gberry@Etch:~$ glxinfo
name of display: :0.0
display: :0 screen: 0
direct rendering: No
server glx vendor string: SGI
....
server glx version string: 1.2OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.5.1)
....

Infine:
se da Desktop-Amministrazione lancio "Ati Control Panel":
appare:
"Fire GL Control:Driver does not provides FireGl X11 extensions! Panel components will operate only partially."

Come posso risolvere?

Grazie in anticipo a chi mi vorrà aiutare.
