See https://lists.ubuntu.com/archives/ubuntu-devel/2010-July/030995.html for our last attempt at this.
Once again, we've enabled gfxpayload=keep in GRUB to see if we can get to the point of having (nearly?) flicker-free boot on a wide swathe of hardware for Natty. In fact, we did this in grub2 1.99~20101124-1ubuntu1 on 24 Nov, but I'm just getting round to announcing it. We'll be making a few extra changes before Christmas in order to make the GRUB->Plymouth transition visually smoother, without a black screen in between. The kernel team has already managed to isolate one major cause of failures in this environment and get it fixed upstream, namely https://bugs.launchpad.net/bugs/683775; this happened to Intel users because the pipes and planes ended up not being connected up properly. This was fixed in linux 2.6.37-8.20, so make sure your kernel is at least that recent. If you find that your screen stays black or is corrupted on boot with these changes, please report a bug on the Ubuntu kernel (using 'ubuntu-bug linux') and add the 'kernel-key-gfxpayload' tag. You can work around it temporarily by setting GRUB_GFXPAYLOAD_LINUX=text in /etc/default/grub and running 'sudo update-grub', but we still want the bug reports because that way we might be able to fix them properly. If all else fails, we now have a mechanism that should allow us to blacklist individual cards that have problems with this system.
