Display brightness not changing

post #1 of 10
Thread Starter 
I've got an Acer aspire 5749-6427 i3 laptop on ubuntu 11.04

Everything works like a champion, but the display brightness. When I try to change it, the icon in the top left right appears, showing the changing brightness, but the screen stays at 100%

In windows it works, and at the grub unit it works, just not in the OS.

What should I do to enable it? Perhaps updating the kernel (I don't know how to do that and i'm on 2.32.1)

thanks band.gif

^ there is

the buttons work, as I said, (it's the same to adjust the sound, fn + left right arrows for sound) but for brightness (fn + up down arrows) it just has the notification appear in the top right

EDIT: Rookie, you're right, I just didn't read it correctly. Switching between windows and all, I quoted the gnome version

You might have to install a new kernel as it might add some support that could fix this but I'm not promising anything. On the otherside I have a good feeling that it's more related to ubuntu and unity being the problem. Can you try out a live usb of another distro and report back? Or we could try this out:

Update your system to the newest release of Ubuntu. The new kernels should support laptop display and volume keys..

I'll try updating to 11.10 right now, I can still do homework during the upgrade. Will post back when it's done

Is this your first time trying an distribution upgrade? I'd be wary about it. Keep an eye on packages is all I can say. Hopefully it doesn't go bad for you. I tried it once when I first started out and pulled the short straw. frown.gif

Hope something helps you out on that problem. Just sucks about the whole ACPI problems that creep up every now and then.
