Bug Description

Currently, several Dell laptops contain Intel graphics cards. The Intel driver reports that it is able to change the display brightness, however it also reports the number of levels supported is zero.

In cases such as these, gnome power manager should fallback to the functional
HAL Backend if it's available for the laptop.

When falling back to the HAL backend, since the laptop supports the brightness changing from the HW key rather than trying to force a value change, some changes are necessary in that logic too.
----

IMPACT:
This is a low impact problem, but a regression from Hardy

ADDRESSING:
This has been addressed in upstream stable gnome 2.24's svn tree as well as gnome trunk. It has been included in Jaunty as well.

TEST CASE:
This is only "known" to affect the Studio 1535 and 1537, but likely affects other platforms too. It can be reproduced by trying to press the brightness keys on such a platform. No popup OSD is observed.

REGRESSION POTENTIAL:
The code doesn't introduce any new methods, but simply adds better logic handling for corner cases. The risk for regression shouldn't be high.

I had this issue on a Dell xps 1330, I confirm that gnome-power-manager 2.24.0-0ubuntu8.1 from intrepid-proposed fixes it. Good job guys :)

I had an issue (tracked in bug 261721) where adjusting brightness caused loss of most keybord functionality, thankfuly updating to a proposed linux-image fixed that problem, but sadly broke my on screen indicator for brightness.

I can now happily report that updating my gnome-power-manager has corrected this second issue.

So for reference I am running a Dell Inspirion 6400
gnome-power-manager 2.24.0-0ubuntu8.1
linux-image-2.6.27-10.20

One additional point, the graphics card in my laptop is not intel, but nvidia.

I also had this issue on my Dell 9300. I can confirm that the upgrade to gnome-power-manager 2.24.0-0ubuntu8.1 has fixed the problem. My graphics card is also an Nvidia and not Intel.
