Running Ubuntu 14.04 on Yoga Pro 2

Ubuntu running on Yoga Pro 2

I just got a Yoga Pro 2 and installed Ubuntu on it, works great.

Create a USB boot drive with another Ubuntu machine, plug the USB stick on it.

Yoga Keys boot key

F12 - Boot menu to select booting from usb drive
F2 - Bios Menu

Power down the computer. Push the “novo” button ounce or press F2 while booting, to force the computer to enter into BIOS menus. Disable “Security Boot” and disable “Lenovo Fast Boot”. Leave UEFI option turned on since Ubuntu 14.04 supports UEFI out of the box. I also enabled the Functions keys in the BIOS by default, but this is not required, personal preference.

After install

Ubuntu will boot with full resolution, leave that alone for the install if you can work the installer at that resolution, otherwise change "scale for menus" in settings screen panel. Select the partition size for Ubuntu let the Ubuntu installer resize your windows partition. Grub will have an option to boot windows after the install is done and will setup Ubuntu as the default OS.

After the installation is done, change go the System Settings->Displays and change the "Scale for Menu" to 2.

In Ubuntu 14.04 to make bluetooth and wifi work you need to blacklist the ideapad_laptop module
$ cat /etc/modprobe.d/blacklist-ideapad_laptop.conf
blacklist ideapad_laptop

After this reboot the laptop, this will enable wifi, bluetooth.

What works

Almost everything works great out of the box in Ubuntu 14.04, there isn't many changes you need to do.

Sound works

Options keys for sound work, side sound button up/down works.

Screen

Everything works, brightness, resolution changes, even the option key to turn off the screen and brightness. 

Sleep works

No issue.

Keyboard works

Keyboard background light works, menu key works, Special Fn key mute, volume up, volume down, turn off screen, refresh, brightness up and down, menu key, keyboard light, side buttons for up and down volume,  show all screens, work as expected.

Wifi and bluetooth works

No issues.

Does not work out of the box

Special Fn keys, side mute button, disable track-pad function, air-plane mode function,.

Optional SSD tunning

This fstab change is optional and should reduce the amount of writes to your ssd, no real problem here just a personal preference.
In Ubuntu 14.04 fstrim is enabled by default on /etc/cron.weekly/fstrim, no need to tweak anything else for SSD.

On /etc/fstab file change the root mount line to add extra parameters and mount /tmp and /var/tmp as a tmpfs, as described below:

UUID=9-5-4-a / ext4 noatime,nodiratime,discard,errors=remount-ro 0 1
tmpfs /tmp tmpfs defaults,noexec,nosuid 0 0
tmpfs /var/tmp tmpfs defaults,noexec,nosuid 0 0

Setting to use Hi-res

Ubuntu 14.04 supports Hi-res be default, just go to Settings->Displays and set the Scale for Menu to 2.
