I am running Ubuntu 12.04 and I love it! The only problem is the keys for my brightness, F6 and F7, does not work when I am on battery power or AC power. It randomly works after I am idle for a while and log back in. The other weird thing is to see my battery indicator, I need to toggle my touch pad button that is right above the actual pad on and off for it to show up, and then back on so I can use my touch pad, obviously. The only other Fn buttons that work on my laptop is the button to mute F1 Touch pad on and off F9 and Fn+3 and Fn+4 for my volume.

The only Fn buttons that I care if they work again are my brightness, which again, are F6 and F7

1 This is a known bug for Toshiba Laptops. It states that booting normally, the brightness keys work, and then after suspending, it does not. Only after a normal boot does it work again. My problem is the exact opposite: normal boot, brightness keys do not work; after suspending, they do work. – JAMES PARENTE Jun 9 '12 at 21:27
Not to be impatient, but is my issue too specific? Is there a certain thread I should have gone with my question? – JAMES PARENTE Jun 18 '12 at 11:25

I have a Toshiba L840 and there was actually a bios setting that I had to change that had to do with how the Fn (Function) key works. Take a look in your bios and see if you have an option like that.

Can you include the exact BIOS setting or option you changed? – Peachy Sep 28 '12 at 2:14
How you did that?! What settings you worked on?! – user61928 Sep 28 '12 at 7:51
