Re: [Bug 207473] Re: Screen brightness double level changes on Dell laptops
The Fedora fix seems much more elegant and less invasive by simply finding and eliminating a software keymapping duplicate of hardware/bios activated keys, if it's the same issue!

[Bug 207473] Re: Screen brightness double level changes on Dell laptops
I think it's not just the brightness, either. It seems to be the multimedia keys as well. Just trying to pause the music player with the pause button on my Dell XPS M1330 is very difficult, because pressing the pause button sends it twice, so the music pauses and instantly unpauses. If I tap it a bunch of times, I eventually get lucky and end up with an uneven number of keypresses received.

[Bug 207473] Re: Screen brightness double level changes on Dell laptops
I was using Ubuntu 11.10 (32 bit) on a ThinkPad W510, and having this problem. Fn+Down decreased brightness by 2 steps, and Fn+Up increased it by 3 steps. I just changed my installation to Xubuntu 11.10 64 bit, and am having the same issue, thus it's not specific to Gnome nor KDE. I don't have HAL installed. The two commands below have no effect: /etc/init.d/acpid stop /etc/init.d/hal stop (No such file or directory) The temporary workaround is described in the comment by Kuba Górski.

No. This bug can be found in kde and gnome. It looks like hal-related bug. You can switch to console (Alt-Ctrl-F1) and change brightness by one step. This behavoir is known since April 2008...

Thanks Steve, After I looked more deeply into the problem, I found that the problem is not with brightness level changes -- it changes correctly when I press Fn+Up/Down keys. The problem is that there are 6 brightness levels (as reported in '/proc/acpi/video/VID/LCD/brightness'), which are 12, 24, 36, 48, 60, 72, 84 and 100, whereas the brightness pop-up (of the new notification system) shows 7 levels; That's why it seems to get confused when showing the brightness levels while the brightness is changing correctly. For example, when LCD brightness is at level 0 (lowest), it still shows the brightness at level 1. I don't know exactly which package I should submit this bug against. Could you help?

The problem is that there are 6 brightness levels (as reported in '/proc/acpi/video/VID/LCD/brightness'), which are 12, 24, 36, 48, 60, 72, 84 and 100, whereas the brightness pop-up (of the new notification system) shows 7 levels; That's why it seems to get confused when showing the brightness levels while the brightness is changing correctly. For example, when LCD brightness is at level 0 (lowest), it still shows the brightness at level 1. I don't know exactly which package I should submit this bug against. Could you help? And sorry if I disscussed the isse in the wrong place.

[Bug 207473] Re: Screen brightness double level changes on Dell laptops
Can somone confirm that the bug is fixed on Dell m1330 with intel graphics? I have such a model and I keep seeing double changes in brightness when I press FN+Up or Down and g-p-m is running. Also using latest intel drivers did not help. Using the .30 mainline kernel does give one-step increments, however the scale of the slider gets much bigger than eight steps as it should be on this model. -- Screen brightness double level changes on Dell laptops https://bugs.launchpad.net/bugs/207473 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 207473] Re: Screen brightness double level changes on Dell laptops
I can confirm that this is fixed in my Dell Inspiron 6400. But a new problem is introduced: when pressing Ctrl+Fn Down immediately after Ctrl+Fn Up (or vise versa), the brightness continues to go up, as if it has an inertia. Of course, this may be a bug with Jaunty's new notification system.
