howto activate dri on radeon xpress 200

[t0bias]

hi,

the fglrx-driver from ati (8.35.5) worked for me quite well,
i cannot get any direct-rendering acceleration though.
the Xorg.0.log says

-- snip --
(II) fglrx(0): Composite extension enabled, disabling direct rendering
(WW) fglrx(0): ***********************************************
(WW) fglrx(0): * DRI initialization failed!                  *
(WW) fglrx(0): * (maybe driver kernel module missing or bad) *
(WW) fglrx(0): * 2D acceleraton available (MMIO)             *
(WW) fglrx(0): * no 3D acceleration available                *
(WW) fglrx(0): ********************************************* *
-- snip --

did i miss to install something?

thanks,

toby

Try adding these lines to your xorg.conf

Section "ServerFlags"
Option "AIGLX" "off"
EndSection

Section "Extensions"
Option "Composite" "False"
EndSection

so it looks something like this

# Xorg configuration created by system-config-display

Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Section "Module"
Load "extmod"
Load "dri"
Load "glx"
EndSection

Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105"
Option "XkbLayout" "us"
EndSection

Section "Monitor"
Identifier "Monitor0"
ModelName "Autodetect"
# HorizSync 31.5 - 90.0
# VertRefresh 59.9 - 60.1
Option "dpms"
EndSection

Section "Device"
Identifier "Videocard0"
Driver "fglrx"
Option "VideoOverlay" "on"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768" "800x600"
EndSubSection
EndSection

Section "DRI"
Group 0
Mode 0666
EndSection

Section "Extensions"
Option "Composite" "False"
EndSection

Section "ServerFlags"
Option "AIGLX" "off"
EndSection

Did you use the ati livna driver? if so you will need a i686 kernel for this driver to work.
to check type this command.

rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}\n"|grep kernel|sort

If you used the ati homepage driver did you build rpms i.e .

/ati-installer.run --buildpkg Fedora/FC6

If you run this installer without the rpm build option you will need to uninstall it first!
