[dapper] X broken, Permission denied

[SmasSive]

Hi,

I recently upgrade X to 7.0.0-ubuntu10 and when I rebooted the  
computer, X wasn't start.
Firts of all, it says that I hadn't permission to read  
Xwrapper.config, as root I changed this to 666, then I got the error  
before explained.

Searching the forums (broken?) I don't see any problem similar, I'm  
the only one with this? Any solution?

Thanks to all and sorry for my english.

See you!
