You don't even state which model you have. Which limits my ability to comment. I know i've had no problem with mine.
The best things for you to do is check the specific model info from linux-on-laptops.com and search, then ask, on the linux-sony list http://returntonature.com/mailman/listinfo/linux-sony
Good luck.
