Look for this entry: do as directed, you may have to uncomment the back port server addresses.



## Uncomment the following two lines to add software from the 'backports'
repository.
##N.B. software from this repository may not have been tested as
## extensively as that contained in the main release, although it includes
## newer versions of some applications which may provide useful features.
## Also, please note that software in backports WILL NOT receive any review
## or updates from the Ubuntu security team.
deb http://ca.archive.ubuntu.com/ubuntu/ intrepid-backports main restricted universe multiverse
deb-src http://ca.archive.ubuntu.com/ubuntu/ intrepid-backports main restricted universe multiverse

next step:

sudo apt-get install linux-backports-modules-intrepid

then reboot.

Worked for me.
