since grub 1.99~2010112-0ubuntu1, with nvidia proprietary driver, I can't get a working X/gdm, just a black screen after plymouth is shown. Colin pointed me to the framebuffer spec and I saw that gfxpayload=keep is activated. I remember having issues with it in maverick already, and see not anymore this pb once this option is disabled.
how can I help getting the relevant info to you?

It is a highly likely that this is a similar issue to that we saw with Intel. That the driver is not expecting the card to be configured, and getting into a mess trying to program it from that state. As these are the proprietry drivers and we cannot debug them, it seems appropriate to unconditionally disable pretty boot when they are installed.
