I just bought a Dell Studio 15 laptop and immediately installed openSUSE 11.1 on it. After spending 2 days playing around with various issues I managed to install/configure the graphics driver and got desktop effects to work. Here's how I did it:
Download latest Ati driver from http://support.amd.com/us/gpudownload/Pages/index.aspx
Login as root and execute the file
From the UI screen select “Generate distribution specific driver package
NOTE: I tried opting the first option "Instal Driver 8.65 on X.Org...
" and managed to get it to work but the display was very slow and was kind of dragging. So I suggest you refrain from doing it.
After selecting “Generate distribution specific driver package”
Agree to the license and select the SUSE package - SUSE/SUSE111-AMD64
You'll get a file - fglrx64_7_4_0_SUSE111-8.65-1.x86_64.rpm
Now make sure you have the following packages else instal them:
sudo zypper in kernel-source linux-kernel-headers kernel-syms module-init-tools make gcc
Then install the file - fglrx64_7_4_0_SUSE111-8.65-1.x86_64.rpm
rpm -ivh fglrx64_7_4_0_SUSE111-8.65-1.x86_64.rpm
To configure xorg to use fglrx (ATI) driver, log out, switch to the terminal by pressing Ctrl-Alt-F1, login as root, and type:
# init 3
# aticonfig --initial
# init 5
It works for me and I hope it does for you too.
I'm able to run on 1920x1080 resolution and using Compiz Desktop effects too.
I referred the section "The command line way" of the page - http://en.opensuse.org/ATI_Driver_HOWTO
The last step regarding configuring using sax2 didn't work for me. I got a blank screen when I did
SaX2 -r -m 0=fglrx
So I instead used
The section "Step 4 - Configuring the newly installed ATI driver" of the page http://en.opensuse.org/ATI/The_Hard_Way
