Comment 3 for bug 456637

I think it's unrealistic to expect a new user to fix the problem by booting from a live CD and create a text file in the right place, etc. If a first time karmic user is bitten by this bug, and cannot login, he/she is likely to scrap the Ubuntu install altogether and move on to something else. Hence my appeal that Uubuntu developers seriously consider turning off powermizer by default and make it optional. This would not have been an issue in the past because older drivers did not have this problem. But without this workaround, a lot of people will find themselves locked out of their Karmic boxes.
