[Hardy] laptop function key + brightness keys combo activates twice if pressed once.

[manny]

my laptop is a Dell inspiron 1420

the problem is as the title described: "laptop function key + brightness keys combo activates twice if pressed once."

It makes the screen too bright or too dark with just 1 key press.

i also have gutsy installed and it works fine.

gnome panel brightness applet works fine too.

very annoying little bug, specially when reading on screen.

thanks

Same story on Dell XPS M1330.

I can reproduce this on my Inspiron 1420 with Intrepid. (I've seen this issue since Hardy at least.)

I'm making a wild guess at filing this against gnome-power-manager, but please refile elsewhere as appropriate.

I think this might be specific to Inspirons - I was able to find another dupe report about this bug, and the reporter also had an Inspiron 1420.

Fwiw, mine is a 1420N specifically.

Do your laptop brightness keys work fine if you boot with the video module blacklisted and then kill gnome-power-manager? If so, what you're describing is probably a duplicate of bug #257827.

I'm also experiencing several brightness level changes (like 5 out of 7) with g-p-m loaded in Intrepid, but only 2 if I kill it.

I have the same issue on Dell Inspirion 1525 + Intrepid.
In addition I have similar problem with volume up/down hot keys - sometimes it jumps over 2-3 or even 4 steps. Is this related somehow?
Everything worked fine on Hardy.

I have "Brightness Applet" on the top panel and when I click the applet icon (do nothing with the brightness slider) and then press Fn + Up/Down combo - usual brightness change indicator do not aper, BUT everything works fine in this case, i.e. brightness changes step-by-step without jumps!
