Find a kernel that supports your video cards. Most of the kernels available through fog support multiple video chipsets. Sometimes the KitchenSink (KS) kernels work better. Use the Kernel updater portion of the WebUI to try different kernels until you find one that works best. If you are up to it, compile a custom kernel that supports your hardware. It’s a bit scary for a beginner, but after doing it once or twice, it gets a lot easier.
