I've a problem with latest versions of fglrx drivers. My system is a Z61p with an ATI FireGL V5200. The latest versions of this driver (since 8.40) gives me a jerking screen. Every one or two seconds my screen stops working for 200-300 msec. Anyone with the same problem, the only version which is working is 8.39 and with this the X crashes from time to time using xvideo. Help!
