Hi. Thanks for helping me.
Here is what I get when I try "cat /etc/X11/XF86Config-4 | grep -i dri"
Load "dri"
Driver "keyboard"
Driver "mouse"
Driver "mouse"
Driver "ati"
Section "DRI"
And here is what I get about dri in /var/log/XFree86.0.log
(II) LoadModule: "dri"
(II) Loading /usr/X11R6/lib/modules/extensions/libdri.a
(II) Module dri: vendor="The XFree86 Project"
compiled for 4.3.0.1, module version = 1.0.0
ABI class: XFree86 Server Extension, version 0.2
and
(II) RADEON(0): Acceleration enabled
(==) RADEON(0): Backing store disabled
(==) RADEON(0): Silken mouse enabled
(II) RADEON(0): Using hardware cursor (scanline 866)
(II) RADEON(0): Largest offscreen area available: 1152 x 7321
(**) Option "dpms"
(**) RADEON(0): DPMS enabled
(WW) RADEON(0): Option "UseInternalAGPGART" is not used
(II) RADEON(0): Direct rendering disabled
Hummm. I don't know what to look for. Should I follow the instruction at
(http://xoomer.virgilio.it/flavio.stanchina/debian/fglrx-installer.html) or
it's not relevant to my problem?
