I have 3 distros : 1 Natty and 1 Maverick on my internal disk and 1
Natty on an external Usb disk, all 64 bits. Andy's modification helped
to boot both Natty, however with better results for my internal Natty
(roughly 50% success for warm boots, and 25% for cold ones) than for my
external one
The bug seems to me not to have been fixed. It takes me up to 6 to 8
tries before any successfull cold boot.
I made the modification suggested by Andy in comment #10. Maybe 1
success for every 8 to 10 tries.
I don't know whether it still makes sense to test the kernel linked at
in comment #14.
Having similar Black screen issue when try boot with ubuntu after
installation completion of 11.04 version on HP Pavilion dm4 CTO-1100
laptop. But 10.04 works fine. Is there possiblity that Ubuntu 11.04
64-bit tries to install restricted graphics driver (AMD ATI Radeon HD
5xxx graphics driver),
I was tryng 11.04 alfa and beta 2months ago and month ago with Multisystem
multiple isos. Older versions are fine 11.04 ubuntu and Xubuntu gave black
screen. On cold shutdown for 1/5th second i saw screen before power went away.
Problem is monitor not showing anything. Its not even making Black
I have an ACER ASPIRE 4736Z and Ubuntu Natty boots to a blank screen. I
did not have problems with Ubuntu Maverick. I have tried lots of boot
parameters with no success. Sometimes Natty boots ok... it seems totally
random.

In my experience some package mirrors need a few days to update all
packets. http://gb.archive.ubuntu.com started to include the new kernel
yesterday. Since then every time the kernel was loaded 12 seconds later
I got the login screen as I am used to. And this with a slow intel atom
processor.
Ok, thanks for information. I have finally got the new kernel also.
But, it seems, I have still black screen after boot. Dell Mini 10v.

Upstream believes they understand the issue, the pipes are running when
we try and reconfigure and our current initialisation can lead to
combinations which would be deemed to produce 'undefined behaviour'.
Testing with the V2 patch from the upstream bug seems to indicate that
the fix there is

As Tim indicates there is an element of a race to this issue. On my

reproducible in 20 reboots. I scratch installed from the same Natty

Ok this seems to be fallout from grub2 handing off the display in
graphics mode (gfxpayload=keep). Switching this back to text resolves
the issue.

This appears to be a regression from 2.6.37-6.17 to 2.6.37-7.19. I'm
suspecting these commits likely have something to do with it:

UBUNTU: [Config] build in CONFIG_AGP_NVIDIA
UBUNTU: [Config] build in CONFIG_AGP_AMD64
UBUNTU: [Config] build in
Well, that wasn't it. Rebasing against 2.6.37-rc4 and adding Dave
Airlie's pull request from Tue, Nov 30, 2010 yielded similar results,
i.e., zilch.

With 2.6.37-7.19 the display will correctly initialize about 1 in 5
times from a cold boot, and never AFAICT from a warm boot. However, the
good news is that it recovers the display 100% of the time after a
suspend/resume cycle. I've experimented with unplugging the battery
and/or booting with
45 matches
