Frej, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please provide the information following

Hi.
On the UL30VT (and other models in this series), I can't select graphics
chipset under Linux (and I believe they are both powered up chewing
juice, but that is a separate bug). The nvidia seems to be the active
one being used by X.

You can often change them in the BIOS, too. Does that work on that
model?

There is no supported way under the bios to select the graphics card.
There is a button on the keyboard that lets you select which chipset is
in use, but it only works under Windows. I believe it is possible to set
the hard drive to a compatibility mode which has the side effect of
disabling the
Per comment #9, I just tested under Precise and adding
acpi_backlight=vendor to the kernel options has the brightness keys

Title:
xrandr says that this machine has xbacklight available, so it's a bug in
the intel or nvidia driver. This seems to be a hybrid graphics machine,
are you currently using the Intel or the NVidia chip? Could you please
try with the other one?

This is still an issue with Natty. The brightness control buttons cause
the brightness slider to appear and you can make the slider go up and
down, but the screen brightness does not change at all.

Bugs,
Thank you for taking the time to report this bug and helping to make
Ubuntu better. A new version of GNOME Power Manager is available on
Maverick and we are wondering if this bug is still an issue for you with
that version? Could you please test and comment back? Thanks in advance.

Same here. Asus UL50 (both UL50A and UL50V). There is reaction
(notification on the screen) to hotkeys Fn-F5 and Fn-F6 but it doesn't
change brightness and the notification appears with huge delay (If I
press 5 times last is about 5 minutes later :/ )
It worked fine on 9.10.

I have one idea
when You open this file
sudo gedit /proc/acpi/video/VGA/LCDD/brightness
You probably get
levels: 4 10 16 22 28 34 40 46 52 58 64 70 76 82 88 100
current: 16
the only chang that I can see is 4 to anything else so probably there is
a problem with scale.
Maybe it should not go up

Solution to brightness problem can be found here. Although it's works a bit

it, now it works just liked in 9.10.

Same (or similar) problem with ASUS X5DIJ running ubuntu-10.04-desktop-
amd64. Strange, since worked OK with 9.10 64 bit (ubuntu-9.10-desktop-
amd64).
Neither the function keys nor the panel applet actually affects the
brightness. The power management centre also has no effect.
Same here UL30VT
