Nowadays mostly all hardware is supported and works very well, especially if you use vendor drivers.
You can always drop the themes(and even the whole package) and use a default KDE installation. It's better to compile almost everything locally.Suse is heavy and the default GUI themes are crappy... I've tested about 20 distros in a year and, apart from the two mentioned above only Pardus and Mepis someway satisfied me (but not enough to keep them obviously...)
