If you found problem to start x-window in your debian system maybe this is the answer.
First you must install all the packages for ATI driver. The packages are fglrx-driver (the core driver, you can install only this package but you won’t get 3D capabilities, not worthed hah), fglrx-kernel-src (the driver to enable your 3D power), fglrx-control (control panel for your ATI). Because the driver place in Non-Free directory in Debian, you won’t find it in your CD or DVD distribution so you must download them with your self. There are several ways to install and get the packages.
I assume that you are root and use the i386 platform
1a. Install and get the packages with apt-get command
apt-get install fglrx-driver fglrx-kernel-src fglrx-control
if you don’t need the last two just exclude them
1b. Download with your browser and install in your home directory, if you used lynx you will get some problem when installing directly from the website. install in home directory with
dpkg -i fglrx-driver_8.28.8-4_i386.deb
dpkg -i fglrx-kernel-src_8.28.8-4_i386.deb
dpkg -i fglrx-control_8.28.8-4_i386.deb
Make sure that all the depended package are already installed.
The information can be found in http://packages.debian.org/stable/x11/
2. Compiling the kernel
module-assistant prepare
module-assistant update
module-assistant a-i fglrx
It will arise some errors but no problem just do the next step
3. Execute this command
aticonfig –initial
4. Confirm if it works
fglrxinfo
5. Try the x-window if you have any problem, execute this command
dpkg-reconfigure xserver-xorg (for debian 4)
dpkg-reconfigure xserver-xfree86 (for debian 3)
6. Try again the x-window if you have the x-window started but with blur image try step 3 again, after that execute startx to start x-window
I hope your debian will works as mine, feel free to ask
