I have the same problem in 13.10. I didn't realize that it was basically in beta as of now but many people with 13.04 seem to have the same problem. I've looked up so many tutorials but none of them are working.

This might work for you. After doing this restart your pc and adjust brightness using fn keys.

It works fine for my Acer Aspire 57427 / 4474. Very good thank you so much.

Huge Thanks for sharing this us :)

That is to reduce the spreading of germs not because people are lazy. Your supposed to tap the faucet with a wrist or and elbow instead of turning a handle with germy hands. Ha lazy people who assume the reason things are the way they are without actually being informed(I mean you)

It's a sanitary reason

For only 50$!

It's $50 for a pack of 2

Thy have something like that some security systems work off your phone and give you live video feed and the ability to turn on/off lights and lock doors

Now if only I had some device to activate my light switch for when my phones too far away.

+Hissatsu5 you can't dim the lights tho.

+Michael Mathis A lot of LEDs are rated for that, and while its often technically true for the LED die itself I'd expect the components in the driver circuit to fail much earlier than the LED itself in most cases.Also I wouldn't be surprised if the operational temperature in a lot of designs will exceed the conditions they're rated at, so some derating due to temperature would have to be factored in. Some electrolytic cap or transistor will probably release the magic smoke well before the LED itself does I'm afraid. Still that doesn't mean they're bad products in general, some cheap bulbs can be HORRIBLY NOISY both on the mains and EM radiation especially the pwm regulated ones. But unless you're seriously into electronics or got some really delicate instruments at home that last part is unlikely to be a real issue for you as a home user.

@0SmooK0 Thanks,, God bless you, Charlotte

thank you i learn a little

Thank you very much.

Thanks! I could have figured that out myself... and it would have only taken me a few hours. 8)

So what if you uncheck the box, and drag the brightness all the way down? how do you fix that?

It should still be light enough in a dark room to be able to see the scale and slide it up.

thx bro!
