While typing normal keys I have to press fn (function key) as it seems that the function key is pressed all the time.

What I have to do to make the function key off and it trigger only when I presses it.

Any help will be appreciated!

It sounds like the key is stuck. Try carefully removing the key, and clean it, and underneath it. –  Mitch Jul 5 '12 at 7:47

Finally I got the solution, after doing some random key pressing!

Infact there was key numLk, so i again press Fn+numLk and my keys started working properly.

I had the same issue... weird though that it gets "pressed" automatically at reboot.. –  lucacerone Nov 3 '13 at 12:09

There might be a setting in your BIOS for this. I know that some laptops use the F1-F12 keys for special functions and require the function key to be pressed for normal key use. Try running your BIOS setup while booting and look for an option you can change.

Okay I will look into it! –  dearvivekkumar Jul 5 '12 at 15:59
I have checked into the BIOS for keyboard/function key setting, But I didn't get any. Moreover I found while entering the password at startup. Normal keys are working, But after logged into, pressing the same key result as if that key is pressed with function key. Is there some way I can fix it? –  dearvivekkumar Jul 6 '12 at 6:18

Lately I've been having the same problem across Ubuntu 10.04 (LinuxCNC edition), 11.04, and the late stable 12.04. I have an Acer Aspire 4535. The combo Fn + numLk doesn't work and my BIOS doesn't have any key customization, and then I've found the error message about Compiz in Ubuntu 12.04 and tried reinstall it with the following command:

sudo apt-get install compizconfig-settings-manager

And now the Fn key is back under control. I almost thought this was a hardware problem. I'm a newbie using Ubuntu so i don't know what actually happened to Compiz, it just works now.

Try to press ESC(FnLk)+Fn. This help for my Ubuntu 14.04 LTS + Lenovo Thinkpad E540.

What is FnLk .? –  Tim Aug 20 '14 at 13:14
@Tim FnLk is Function Lock. This really does apply to some laptop keyboards. –  Eliah Kagan Aug 20 '14 at 14:54
