People please reply!
Have you tried re-installing the manufacturer provided drivers?
I did that and it worked, I put in the CD that came with the laptop and downloaded those drivers. Thanks! The brightness works now, and so does the start menu. The driver I was using must not be stable for my laptop yet. The Skype icons are still pixelated, but I guess it's just a derpy version of Skype.
Glad you got the problem fixed. I've been having the same problem and have not found a permanent solution. I am looking for the drivers that you reinstalled from the CD because i have a XPS 14z and it came without the CD with the drivers (or I may have lost it). Is there a way you could upload a copy?

Make sure you backup your registry first before proceeding!!!!
open regedit in Run Command
Registry has wrong value:
Currently reads as :
"Edit DWORD 32 bit"= f000
Registry with New Value:
You needed to change the value in registry to: ( f008 )
"Edit DWORD 32 bit"= f008
Then Restart Computer
