This bug was filed against a series that is no longer supported and so
is being marked as Won't Fix. If this issue still exists in a supported

** Changed in: linux (Ubuntu)
Declining the Maverick specific nomination for now and leaving this open
against the actively developed Ubuntu kernel (which happens to be
Maverick at this time). Will re-open the nomination should a fix be
narrowed down which we can confirm specifically resolves this issue in
Maverick.

I' also have the problem on lucid with a Clevo M570RU - but the fix is
simple:
Compile the ac part of the kernel as module and the issue is fixed. I
assume there is some kind of race condition in the detection code of the
ac adapter. As far as I know, many distibutions already do it this way
and
Fixed in the latest Maverick kernel builds! I'm so happy. Grab the
latest kernel from the mainline kernel PPA and set Powermizer to Maximum
Performance and it'll go all the way up! :D

How is possible that lucid have the same problem. I use Kubuntu and I've to
compile the kernel manually to detect the ac adapter. If I don't do thank, KDE
put the system to extreme powersave with the ac adapter in!!!

From what I can gather, Gnome powermanager partially displays the status
correctly. If you look closely, it will be sort of correct, but it still
isn't really working. I believe this has something to do with how it
gets its information, which includes the BATT entries in /proc/acpi.

I too have this problem related to nvidia powermizer on Karmic with a

Same problem on Clevo M570 and W760. With AC Adapter as module, it's ok.

At this point, all that needs to be changed is the ACPI_AC adapter flag in
the default kernel configuration needs to be changed. Its getting annoying
at this point, because every other linux distro I use has done it this way
for years and its not a problem. Anyone got any ideas on how we can
Not really. Truthfully, I don't know of a more popular bug reporting

And yeah, this is extremely annoying already. Having to compile my own

I don't know why, but I've compiled the ubuntu kernel for karmic
(2.6.31-17) with the acpi module (battery, ac, etc) loadable
externally and so the ac adapter finally works.
I'm a newbie with kernel compiling, but if someone want it to try, I

We've already gotten to that point here. We've been using KernelCheck

compiling the kernel every time a new one is released. Prferably a full
blown fix for the
Just as a heads-up, this bug is still affecting me in the newest Lucid
alpha release. (I have the same model of clevo as the others here, the
serval professional).
Here's a really stupid question though -- is there anyway whatsoever to
make a false directory structure under /proc/acpi/ac_adapter?

Although this didn't work for me, since I'm using the Jolicoud kernel,

solved the issue.

You probably didnt have the new kernel loaded before you uninstalled it.
Ubuntu defaults to the standard kernel unless you reorder your entries
in grub (there is some way to edit the comments in /boot/grub/menu.lst
to do this automagically via update-grub, but i dont remember how). Glad

Quick question: What kernel version are you currently using under Arch?
Because after messing around with this one for a few hours, I've come to
realize that my power button no longer works. I had to use the GUI to
put my computer to sleep, and once it was suspended it wouldn't wake up.

It takes some configuration to get it to work in arch. By default it
loads as a module, but i've always had to load it apart from the other
modules (disable it by default, and load it at the end of rc.sysinit).

Arch on my desktop right now to try it out, I'll take your word for the
payoff. As for the power button not working on my laptop, I'm going to

Oh geez. Get ready for no config. Its roughly equivalent to Gentoo, but
with binary packages. The archlinux wiki is very helpful for configuring
things, and its very open ended. If you have any questions, feel free to
ask.

Well I've used Sabayon before, so being that it's a bit like Gentoo (but
pre-configured from the start), I think I'll have an easier time than
you'd think. Sure, Ubuntu has a great packaging system, but thank the

Good to hear. As for the virtualbox, really? Im running a copy in
virtualbox right now, and although the vbox drivers were a bit hairy to
get setup, it works great now, mouse and autoresizing included. Now,
granted, this is using fluxbox as opposed to gnome, but that should make
things more
I'm fairly certain that the vbox issues I'm having are also an effect of
the new kernel. Never had these issues with 2.6.28. I'll probably
switch back if the generic kernel doesn't turn out to be anything good.
Apparently there was a new bug introduced in 2.6.31 that required the

What version of virtualbox are you using? I'm curious now, I have version
3.1.0 for reference. Also, what do you mean by stuttering/pausing? Is there

tell. Thanks.

Worked perfectly. I realized while I was starting up KernelCheck that
by default (as of today), it will install kernel version 2.6.30.5. This
is actually older than the Karmic kernel, and is not the newest version.
If you go to 'Custom Install', select 'Install older prepatch' and

Confirmed this issue from the latest Karmic, as well as Jaunty, Fedora
