Comment 35 for bug 532436

I just wanted to update from Jaunty to the latest and greatest LTS but i heavily regret having done that.. fortunately i clonezill'ed the system before the clean install.
But how such a problem slipped into an LTS?
I experience the same problem with any version of the nvidia drivers:
With a clean install ubuntu10.04-64:
  - tried ubuntu-supplied nvidia proprietary drivers, the problem arise;
  - tried x-swat repos, same problem;
  - tried nvidia-supplied .run packages, same problem with both 195.xx/256.xx;
It's much worse now, after a reboot it loose configuration settings for some applications, this time gedit loose its entire preferences.. i just don't know what's happening..
