Asus X201E Ubuntu 12.04 ( Function Keys )

I recently bought asus notebook X201e some time ago. Since I am a fans of Ubuntu, I just installed Ubuntu LTS 12.04, I chose it because the support of the old and very easy to use. Once installed, there are several issues that arise are the function keys are not used. By doing the test a few pointers on google, finally I got the solution and it can work well.

The first step is to upgrade the kernel ubuntu 12.04 by default is 3.2 to 3.5 following is how: Add repositories of Ubuntu 12.10 by editing “/etc/apt/sources.list”

sudo vim /etc/apt/sources.list

and add following lines:

deb http://security.ubuntu.com/ubuntu quantal-security main universe restricted multiverse deb-src http://security.ubuntu.com/ubuntu quantal-security main universe restricted multiverse deb http://archive.ubuntu.com/ubuntu/ quantal-updates main universe restricted multiverse deb-src http://archive.ubuntu.com/ubuntu/ quantal-updates main universe restricted multiverse deb http://archive.ubuntu.com/ubuntu/ quantal main universe restricted multiverse deb-src http://archive.ubuntu.com/ubuntu/ quantal main universe restricted multiverse

Then update and install the kernel:

sudo apt-get update sudo apt-get install linux

For PAE kernel (for intel i386 with more than 4GB RAM) :

sudo apt-get install linux-generic-pae

After that reboot: sudo reboot. Yessss !!!! ..., successfully. The volume setting can walk normally again, as well as wireless and others. But the Fn key for brightness is still not running. After dabbling again, This could be fixed by editing the /etc/default/grub file and changing the line "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=". After running "sudo update-grub" in the terminal and rebooting, the keys were working again. And some functions in ASUS X201E worked. Good Luck
