Which Intel Card do you have? Does your Graphics Card support 3D effects?
Execute this

sudo lspci | grep -i vga

Post output here.

Try replacing intel with i810 in xorg.conf file. In case it doesn't work, post the contents of xorg.conf file here.

I tried i810 and it did not work, I restarted my computer and I got a message saying that ubuntu was going to run in safe mode,

this is the xorg.conf

i had the same problem a week ago, reverting to the old intel drivers from 8.10 worked for me fine (intel is rewriting his drivers)

here is a page with some informations and a link to guide how to downgrade:
