Go to synaptic and search for packages with the word 'fglrx' in the name. Install all that you see. Go to a terminal. At the prompt type 'su' and your password. Now you're root user. Type '
m-a prepare' and '
m-a a-i fglrx' one after another on seperate lines. Now the fglrx driver should be installed. Now all you have to do is change the /etc/X11/xorg.conf file so that it uses fglrx instead of vesa, and then restart.
Go to the directory /etc/X11 and using your favorite editor change the part of the xorg.conf file that looks like this:
Code:
Section "Device"
Identifier "ATI Technologies Inc ATI Default Card"
Driver "vesa"
BusID "PCI:1:5:0"
EndSection
so that it looks like this:
Code:
Section "Device"
Identifier "ATI Technologies Inc ATI Default Card"
Driver "fglrx"
BusID "PCI:1:5:0"
EndSection
Then restart the computer and all should be well. NOTE: The important part is that you change the line that says 'Driver' so that it also says "fglrx" and not "vesa". The other parts of the 'Device' section may be different on your computer.
EDIT: This all assumes you have module-assistant installed. You want to make sure you have module-assistant and anything it needs to do it's job. This also assumes you have Etch already installed.
