It is recommended to use YaST for installation of the NVIDIA driver. There are several reasons for this. First, it's simple. Second, and this is the most important one, you won't need to recompile the nvidia kernel module after a kernel update.
Update your Kernel via YOU (YaST Online Update). Use
YaST -> Software -> Software Repositories -> Add
Protocol: HTTP Server Name: : download.nvidia.com Directory on Server: /opensuse/11.0
to add the NVIDIA http server as additional installation source. Now use
YaST -> Software -> Software Management
to install the NVIDIA driver. The appropriate NVIDIA packages will be autoselected, if your card is supported. These are either
a) x11-video-nvidia + nvidia-gfx-kmp-(kernel_flavor)
or
b) x11-video-nvidiaG01 + nvidia-gfxG01-kmp-(kernel_flavor)
If no additional packages are autoselected, your card is not supported by the driver (RPMs) at the moment.
Use "sax2 -r" for X.Org configuration.
People who aren't afraid of recompiling the nvidia kernel module or even reinstalling the nvidia driver each time the kernel has been updated and want or need to use the latest and greatest nvidia driver can use the following steps 1-3. The others should use the instructions above using YaST and skip the steps below.
1) Kernel sources must be installed and configured. Usually this means installing the 'kernel-source', 'make' and 'gcc' packages with YaST2.
2) Use the nvidia installer for 173.14.09.
sh NVIDIA-Linux-x86-173.14.09-pkg1.run -q
3) Configure X.Org with
sax2 -r -m 0=nvidia (0 is a digit, not a letter!)
NOTE: There is no need to try to enable 3D support. It's already enabled, when the nvidia driver is running.
IMPORTANT: You need to recompile and install the nvidia kernel module after each kernel update.
