UbuntuGnome running on Yoga Pro 2
I just got a Yoga Pro 2 and installed UbuntuGnome from http://ubuntugnome.org 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.
Create to boot USB disk
Avoid using something like Unetbootin to create a UEFI-bootable flash drive, it does not work yet.
Format your flash drive with a single FAT32 partition. Copy the contents of the Ubuntu ISO (use your favorite archiving tool - 7zip for example) or CD to it. Use a recent 64-bit Ubuntu version.
That's all you need to do. No need to install a boot loader or use special tool.
You can also use Ubuntu tool for UEFI bootable flash drive.
After install
UbuntuGnome will boot with full resolution, also Gnome 3.10 supports HiRes. Select the partition size for Ubuntu let the UbuntuGnome 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.
In UbuntuGnome 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 UbuntuGnome 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.
Camera
Works fine.
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, work as expected.
Wifi and bluetooth works
No issues.
Does not work out of the box
Special Fn keys, show all screens, 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
UbuntuGnome 14.04 supports Hi-res by default, no changes required.
Tweaks to make some Apps work better with Hi-Res
Firefox works fine with Hires, but you need to scale to 200% every new web site you open, or install NoSquint and Grab and Drag add ons, to make firefox more tablet friendly.
Chromium renders the site with the correct scale, but Chromium menu is not usable in Hires, chromium supports the touchscreen better than firefox if you wish to use it with the touchscreen Chromium is the better choice.
You can change the scale factor on the cmd line, by running:
gsettings set org.gnome.desktop.interface scaling-factor 1
Run chromium at device scale in case it starts with big fonts.
chromium-browser --force-device-scale-factor=1
Cheese and Totem, have problem with the video scale, it plays and works fine but the video only fills 1/4 of the area it is supposed to fill.

Fonts
You can use the gnome-tweak-tool or dconf-editor to change the font settings for gnome apps.
Firefox and Chrome don't use the gnome configuration for fonts, but you can create a file in your home dir with
gedit ~/.config/fontconfig/fonts.conf
firefox and chrome will use that file.
<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
<match target="font">
<edit mode="assign" name="autohint">
<bool>true</bool>
</edit>
