Video Card

dell 5030 with Ati Modility Redeon HD 4250 Video Card. How do I get and install Drivers for it ?

Try this

I think you need the legacy drivers for the 4xxx series though

have you tried adding the following repos to yast

Index of /mirror/amd-fglrx-legacy/openSUSE_12.2

and then selecting the appropriate legacy driver, 32 or 64 bit version

in software management?
