Laptop worked great on f14, but a problem in f16

[RocketCitySoap]

Hello all,
I have an Acer Aspire 5000 with SiS video. It worked great in f14, and worked great in f16, till I got the kernal update. Now if I log off, or switch users, The screen goes bonkers and unreadable. I have no idea where to start to diagnose and fix this problem. Any suggestions?

All of the 3.2 kernels have cause me lots of hardware issues - I would recommend you set your default boot back to your newest 3.1 kernel until the issues are resolved.
