Comment 10 for bug 278963

Lars:
I know that it will take a lot of time but I would be glad if you could follow these steps from your backup:
1) upgrade only the linux-restricted-modules manually
2) run the dist-upgrade from Update Manager and see if you can reproduce the problem

I believe that doing so will remove any fglrx.ko and nvidia.ko from your system (since we don't ship with these precompiled modules any longer) thus solving the problem. If I'm right then we could hack Update Manager into upgrading the linux-restricted-modules before any other package.

Let me know (and thanks a lot for your time in advance)
