Followed this guide Hardware - Installing ATI Drivers - openSUSE Forums and tried to install it.
The first thing it says to do is install kernel-source. Well since I run an RT-kernel, I installed kernel-rt-source. Maybe I shouldn’t have.
When I got to “sh installer.sh --buildpkg SuSE/SUSE111-AMD64” it fails when building a kernel module. So then I installed kernel-source and tried again. But now when I try to run “rpm -Uvh fg…” it says that the package is already installed, and if I run “rpm -e fg…” it says package is not installed.
- Should I build the package with the source from the rt-kernel? If so, how?
- How do I force-remove this package or something?
Heyup
go into yast and search for fglrx, remove it from there (press minus key)
it should go fine
use locate to search for fglrx, none should be found apart from several xorg.conf-fglrx(n) possibly and the ati.run file you downloaded. (might need updatedb to refresh list)
restore your xorg.conf once removed if hosed by
cd /etc/X11
mv xorg.conf xorg.conf.duff
sax2 -a
after this all should be well.

Thanks, that worked. 
But it fails when building kernel module:
# rpm -Uvh fglrx64_7_4_0_SUSE111-8.561-1.x86_64.rpm

Is it because I’m running an rt-kernel?
I can positivly reply on that; there is no driver for the rt-kernel - yet.
