Can`t adjust screen brightness with the brightness applet or keyboard hotkeys

[Serghei Zagorinyak]

Binary package hint: gnome-power-manager

I`m running Lucid Lynx on hp6735b laptop. Can`t adjust screen brightness neither with the brightness applet, nor with keyboard hotkeys. The screen won`dim when inactive as well. Worked fine in Ubuntu 9.10.

Same here Hp Elitebook 8530p

[Robert Roth (evfool)]

Could you please try the workaround from bug #592592? It might help. Thank you.

[Serghei Zagorinyak (serghei-zag)]

Have tried the script proposed, but it won`t help.

[Serghei Zagorinyak (serghei-zag)]

This bug is fixed in Ubuntu 10.10. kernel 2.6.35-22-generic

[Robert Roth (evfool)]

I can confirm that it has been fixed, works fine now on my HP Probook 4710s.

[Robert Roth (evfool)]

@Serghei Zagorinyak: Can you confirm that it has been fixed in Maverick for you too?

[Serghei Zagorinyak (serghei-zag)]

Yes, the bug has been fixed for my hp6735b.

But recently I discovered that it affects Intel graphic cards used in netbooks. For example, one can`t adjust brightness on Samsung N210. Shall I start a new bug for that or post the "apport" output here?

[Robert Roth (evfool)]

@Serghei: Don't really know the answer.
In my opinion this bug should be set to Fix released, and a new one should be reported for the netbook issue, because something has been fixed (brightness adjustment works on Maverick for the computer you've reported this bug for, and it does work for me too, thus some kind of fix has been released ).

Oops. Didn`t see your reply. Ok, let`s close it. I`ll start a new bug a bit later.
