[gutsy] unable to dim lcd display to maximum level with fn keys

[Davide]

Binary package hint: gnome-power-manager

On Gutsy display dimming doesn't work correctly on my asus V6V.

When I press fn+f5 (dimm-down) once, while the display is at it's brightest state , the display dimms automatically to a very low brightness.
If I try to increse it with fn+f5 (dimm-up) it increse of 1 level and after half a second it fall down again to the lowest brightness, so it's impossible to set again the brightest state with the keyboard.
(using the brightness applet I don't have this problem and I can set any level of brightness)

Killing gnome-power-manager solve this problem.

Same problem on my IBM Thinkpad T41, except the LCD goes to lowest level the second gnome-power-manager starts.

Similar behavior on Kubuntu with guidance-power-manager on an HP Pavailion DV6000T.

Closing screen can cause the backlight to shut-off altogether. Noting that the brightness level per guidance-power-manager is 0.

Setting the brightness levels in guidance-power-manager makes the brightness change... but that does not make use of the brightness buttons (Fn-F7/F8 for this box). When I unplug the machine, the screen dims to where the BIOS thinks it should be for battery-power (as set by the Fn-F7/F8 keys the last time on battery). As soon as the "Switching to battery mode." knotify message comes up, the brightness changes again....

Killing guidance-power-manager does *not* fix the problem for me however...

Can I shut off the power-manager handling of these events? and can I get the Fn-keys to work again? This all worked in Feisty. I just rebuilt the box onto a new hard drive this weekend. Mostly a good upgrade, but this is not good.

Hi there
Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you?, Can you please try with the live environment of the Desktop CD of the development release - Hardy Heron?

Thanks in advance.

I'm so sorry that I'm so late....
I've just installed, on my V6V Notebook, the latest hardy alpha release and it doesn't have this bug.
Thank you so much for fixing this issue. Now I can use Ubuntu again.

Thanks for the confirmation, closing this bug due your last comment about being fixed by an upgrade. Please feel free to report any future bugs you might find.
