# Home, End, up ,back arrow keys not working in my Lenovo G580, help me.

I had a bit of work to get brightness keys to work on my laptop. See https://ask.fedoraproject.org/en/question/55033/how-do-i-customise-the-brightness-and-suspend-keys-on-fedora-20/ . You could try dmesg | tail -n 5 when you press one of these keys to see if you get an 'Unknown key' message, or use evtest to see that the keys are detected. You could also just try creating a Custom Shortcut in Settings using one of the keys that aren't working just to see if it's detected at all.
