Comment 19 for bug 1097118

No problem. If you don't have the internet access or time to help us debug this fully then you don't need to.

You can go back to the vanilla Unity packages which should avoid the problem:
  1. Download and install the debs from: https://launchpad.net/ubuntu/+source/unity/5.10.0-0ubuntu6/+build/3412816
  2. Enable "holding" of those older package versions to make sure they're never upgraded:

However if you boot up a 12.10 live session and find the problem is solved then I would recommend simply upgrading to 12.10. But only if you find that fixes the problem.
