Title:
The issue exists for *all* cards, including the newest, and in the
newest drivers from nvidia. It doesn't remember the setting between
reboots, either, which is very frustrating. And the only reason we did
not report it to nvidia as I recall is we could find no means to do so.

Oh and just in case ?I was not clear this affects the latest Ubuntu and
the latest drivers. I don't see a way to indicate that but I believe
we're still where we were before on this.

I just wondering, why you doesn't report this PowerMizer issues to nVidia?
8400M is still supported, so they should fix this in newer builds of the driver.

These are my specs:

I'll be happy to add a quirk for your specific card models. If you have
a card which requires the following line:
Option RegistryDwords PowerMizerEnable=0x1; PerfLevelSrc=0x;
PowerMizerDefault=0x1; PowerMizerDefaultAC=0x1
Please attach the output of the following command:

Is this still unfixed in oneiric/precise?

My experience shows that the bug IS present in Oneric. Moreover the bug
with my particular GT220 video card has been reproduced with 3 different
motherboards. It's the card that matters.
Turning powermizer off in xorg.conf has yet been the only solution found:

I have screen flicker issue Ubuntu 11.04 and nvidia GTX 460M. Seems
every time powermizer changes performance level I have screen flicker.
Only choices in powermizer settings is Adaptive and Prefer Maximum
Performance. If I change to Prefer Maximum Performance there is no
more flicker but setting
A workaround I've found is adding the following line under 'Section Device'
to /etc/X11/xorg.conf.
Option RegistryDwordsPowerMizerEnable=0x1; PerfLevelSrc=0x;
PowerMizerDefault=0x1; PowerMizerDefaultAC=0x1
You may need to restart your machine after that.
Hope it helps.
Reference:
Mind you that setting the nvidia graphics card to Maximum Performance
forcibly may lead to GPU overheating and consequently cause your system
to freeze from time to time. So make sure you have a strong cooling
system, and laptop users may consider cleaning the interior of the
machine.

You
@#25 Maximum performance is not an overclocked setting. I would expect
overheating when overclocking. Not to say that Nvidia cards don't do that
under normal speed, because the ones that don't do powermizer have for me in
the past. However that only happens if you have insufficient cooling.
The people who claim only some people are affected by this bug are completely
off base. This is a bug that affects everyone. It is ridiculous that the
setting for the nvidia powermizer is not saved when you change it unless you do
so by manually editing xorg.conf. It's also pretty annoying
There is no graphical garbage, but there are complete system freezes
from time to time with PowerMizer on using 195.36.31 drivers.

There have been several releases of the nVidia driver that have this
issue for me.
The only way to get it working in linux is to disable powermizer. It
works perfectly fine with the latest Vista video driver.

Sorry, it is not up to you to support a bug. What I am proposing is a
workaround so people don't end up with a unusable system. Don't bother
us, go to nvidia is IMHO not what is Ubuntu about. Don't use
proprietary driver is also a completely unrealistic advice for most
users, you might as well

I do not support this bug. The users with faulty hardware that is
affected by this bug, while significant, are not in the majority. I
would be very frustrated if suddenly an Nvidia update caused Powermizer
to be disabled for me. For most laptop users, this feature is crucial
to obtaining decent
Ah the sweet taste of victory... I could not resist doing a new install
of karmic again now that some three months have elapsed, and it all went
like a breeze - install took less than five minutes! Reboot - everything
is perfect... update and upgrade, and install the proprietary nvidia
drivers
After the bug I had reformatted my system with jaunty; people in the
Ubuntu forums with similar issues had reported that the 190.xx drivers
worked for them because it has a separate powermizer setting.

Btw, I've been using the workaround for over a week now, and it's great!

Wanted to add a me too - I've been experiencing frequent artifacts on
