Comment 23 for bug 516412

Jannis, actually the Arch-linux Gnome problem is a different issue, nothing to do with plymouth.

Those having a Nvidia graphics card really should use Nvidia proprietary drivers (nvidia-current).
And in fact what plymouth is for the time being, it is pretty useless with Nvidia.
I think it is better to remove the package plymouth from lucid, the problems will disappear.
Then you can upgrade the package libplymouth2.
I also have found out that plymouth slows down the boot process and shutdown process in lucid.
