[Q] SMS backlight (cyanogenmod)

Hi guys.

Relatively new to the S3, but I have done a little bit of playing around with Android devices before.

I spent yesterday researching the forums, then manged to root and install Clockworkmod Recovery, and have since flashed the latest nightly of Cyanongenmod 10.

Love it so far, the only problem I've come across is that when I receive an SMS the phones backlight does not come on, which is a bit annoying because I often have it on silent and that's how I see I have a message.

Anyone know if this is just a setting I've missed, a bad flash, or just not supported? I've had a good look around the settings etc and can't seen to see an option anywhere.

Also, I read about the 'phone goggles' mode in cyanogenmod 10, but can't see that in settings either. Am I missing something?

Thanks.
