Acer Travelmate - Backlight always set to darkest possible when changing power mode

[e8johan]

Whenever I attach or remove the power cord to my Acer Travelmate 8210, the backlight is set to the darkest possible setting. I then have to increase it back to where I want it using the Fn key.

The expected behaviour would be to go dark when removing the cord and brighten up when attaching it, or not to touch the backlight at all.

Please tell me what information I need to provide to make this bug report actually useful.

Best,

Johan

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in gnome-power-manager.

I'm a KDE user, so I doubt that it is gnome-power-manager that is the culprit. My guess is that this is the kde-guidance-powermanager...

[Brian Murray (brian-murray)]

That would have been useful to provide in your bug description along with things like the version of Ubuntu that you are running.

[e8johan (e8johan)]

I can see that now, yes. I always use the latest, most up to date version, what ever whas new when the bug was reported. However, I've always had the issue, so it must date back at least two years.

Up through Hardy, Guidance Power Manager is in kde-guidance. For Intrepid and follow it's been ported to KDE4 and is found in guidance-power-manager.

[e8johan (e8johan)]

I'm not using KDE 4, nor Intrepid (as it isn't stable yet), so kde-guidance it is. Sorry for the confusion.

[e8johan (e8johan)]

Wrong package.

[Scott Kitterman (kitterman)]

They share common code except the U/I, so it affects both.

Closing the old kde-guidance task.

Guidance Power Manager has been removed from Kubuntu 10.04 and onwards since it is unmaintained. Unfortunately, this means that no new features or bugfixes will be made.
