This patch merges the fb_powerup and fb_powerdown hooks in a single
operation fb_power with an additional "state" parameter ranging
from 0 (running) to 3 (poweroff).
The geodefb uses state 2 as an intermediate low-power mode, where
the LX or GX video unit is turned off, but the GPU may still be wo
Actually, swap should have been a great solution for B2 machines with a
modern (i.e., >500) image. Theoretically, the additional swap memory
provided by an external usb2 storage device should allow a smoother
execution of memory hungry applications.
In practice, the additional swap did not help,

Because XO Laptops are sold to the public using "Buy 2 Get 1", IMO there should
be a warning to buyer that the machine does not have standard BIOS and cannot
run unmodified Linux, BSD, Haiku or other Operating System.

Why do you feel anyone could mistakenly get this impres
I beg to differ. I have both a B2 and a B4, and running 500+ builds
(currently 595) in the B4 goes as smoothly as expected, but the B2 just
drags itself around. This was obviously primarily due to lack of memory,
so I'm swapping off a 512MB external flash drive and it's still slower
than the B4

That might be true for non-portable operating systems which are bound to
x86, but I dispute that it's true for any well-written application.

Well, sort of.
Generally speaking, it's OK to show confirmation dialogs when there
are ongoing processes (downloads, video compression, export
operations, etc.) which will be interrupted/terminated by stopping the
activity. It's possible there will be other appropriate times as

Andres and I discussed this situation in length last night. Andres
argued that the fb_power() function was not needed and confusing -
really what we are doing when we freeze the DCON is blanking the
underlying video unit. I agree to a certain extent, but I also
think there is value in having dire

Sure. Here is the results from OS603. It seems that there's no much
difference from my past memory. :) However, I don't know why the total

I tried myself too. A few of these seem to come from sugar-shell, the
vast majority are from the datastore-service.
A quick strace run reveals that the datastore-service process sleeps

As I said, I also like this design.
The only thing I could suggest is moving the code snippets that implement
the actual video unit powerdown and powerup to separate functions, so

I suppose that I have effectively opened my mouth and inserted foot, so
perhaps I should volunteer to start a bit of work in this direction.
Any other volunteers? We'll work something out. ;-)
