Upgrading from a HWE backport stack to 12.10 is not supported. You need
to remove the backports first by installing 'xserver-xorg-lts-precise'
which will pull in the original packages and removes the HWE stack.
Upgrades to the next LTS will be supported.

too bad if stock precise fails to work on such hw..
