Brightness Fn Keys Not Working on Asus X401A
Description: Ubuntu 13.04
Software Center: 5.6.0
What I expected to happen:
F5 should decrease brightness and F6 should increase brightness.
Immediately after install, you can lower the brightness half-a-bar and NO further. It is highly annoying because I am stuck with a super bright screen. I am able to turn the brightness down in the settings but this is a temporary fix.
I have tried changing the /etc/default/grub file with the following:
Nothing seems to fix this.
Please can we fix this. I will provide any information needed to help. Let me know what you need and I'll provide it.
Can you help with this problem?
