[opensuse] Screen brightness on HP 6730b
Listmates, I have a puzzling problem on my laptop, a HP 6730b, involving screen brightness. Let me outline the problem by giving you a list of things which don't work as I expect them to. - If I boot the laptop while attached to the power supply, it boots with normal screen brightness. - If I boot on battery power, it boots with dimmed screen brightness. - When booted on power supply and then unplugged, the screen does not dim. - When booted on battery power and then plugged in, the screen does not brighten. - When using the fn-keys to change screen brightness, nothing happens. - When using the brightness slider in the Power Management widget (or whatever it's called), nothing happens. - Powerdevil is configured correctly with different profiles. Switching profiles does not change the brightness. The laptop has a Mobile Intel GM45 Express Chipset and compositing is enabled. In /var/log/messages I don't notice anything about powersaving or some such. Other than configuring Powerdevil (which I have), what can I do to make this work? I am running openSUSE 11.1, with KDE 4.3. Kind regards, Joop -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hi, I also have the same problem with my HP 2230s. fn-keys doesn't work either, I try xev to capture the symbol with fn-f7 and fn-f8 but return NoSymbol. If you only need to change the screen brightness maybe you could try xbrightness [0].

Yes, other powersaving options work with this laptop. I notice that the processor clock speed seems to get scaled and also the fans spin down (when applicable). I'd love for the system to also change the display brightness depending on power source. I'll look into xbrightness to see if this can do what I want. Incidentally, pressing the Fn + F8 or F9 key to set the brightness generates nothing, according to xev. Meaning that xev does not register any key being pressed. Thank you for the suggestions, Joop -- "When you just want a system that works, you choose Linux; when you want a system that just works, you choose Microsoft."

Hmm, not really suggestions. Just that I had similar trouble with OS 11.1 and my (6 year old) Asus M3N. Screen brightness used to work nicely in 11.0, as did the Fn buttons. Both abilities were gone in 11.1 My solution was to stay with 11.0.
