ATI driver problem after upgrade to Intrepid Ibex from Hardy (2)

The fglrx is still can not been used. The problem was described in last post.

The solution for using "radeon" is :

sudo apt-get install envyng-core
sudo envyng -t

select uninstall ATI driver

change the xorg.conf to use "radeon"

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
DefaultDepth 24
EndSection

Section "Module"
Load "dri"
Load "GLcore"
EndSection

Section "Device"
Identifier "Configured Video Device"
Driver "radeon"
EndSection

reboot

Enable desktop effects in Systerm->Appearance->Effects

Enjoy it!!!!
