[Bug 578119] Re: Boot on battery power ends up with black screen [HP tx1000]

[Toni Rida]

I have some new information on this bug.

First I tested on my HP tx2000 with Maverick and the latest updates and
Nvidia version 260.19.12.  Same result, black screen after a battery
boot, ok on AC power.

Then I tested with an upstream kernel as requested by Jeremy Foshee in
post 3 above.  I downloaded linux-
image-2.6.36-020636-generic_2.6.36-020636.201010210905_i386.deb and
sources and installed it.  Next I did a manual install of the Nvidia
driver version 260.19.12.

The result is that my tx2000 now boots through to a normal X server
screen with a battery boot!  So I think this shows the problem is
related to a regression in the Ubuntu kernel patches, especially as it
also works ok in Ubuntu 9.10.

I hope this result can moves things forward a little bit to a solution.
