Ubuntu GNOME 14.10 running on Yoga Pro 2 with HiDPI support

See my previous post on how to install Ubuntu on Yoga Pro 2 for Ubuntu GNOME 14.04.

I think Ubuntu GNOME is the best flavor if you are running HiDPI mode 3200x1200. All screen captured images are at HiDPI resolution.

Until Ubuntu 14.10 is released in October, you can get a daily build of http://ubuntugnome.org for 14.10.

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 14.10 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

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 to create a UEFI bootable flash drive.

Note: Avoid using something like Unetbootin to create a UEFI-bootable flash drive, it does not work yet.


Create a USB boot drive with another Ubuntu machine, plug the USB stick on it. Use the USB 2.0 port on the Yoga pro 2 to plug the usb key, I had problems with the usb 3 port using a usb 3 stick, seems to me it was un-mounted during the installation process, when installer was setting up drives.

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.

The default options will work fine, there is no need to setup custom partitions. But if you want to setup new partitions here is what I did. I deleted all windows partitions since I don't run windows and created efi 512 Mb partition (this is where the efi code looks for the kernel to be loaded on boot, the installer allows you to create this partition with a special type), I also created a swap partition of 9Gb since I have 8Gb of physical memory, a 15Gb partition for the OS "/" and a the rest for home "/home".

After installation

UbuntuGnome ships with gnome 3.12 and will boot with full resolution HiDPI, support enabled.

If the boot process never boots into graphical mode, press CTRL+ALT+F1 to go to a text console, login run

sudo apt-get update ; sudo apt-get dist-upgrade

You can change the resolution in the settings to another resolution, in case you don't want to use HiDPI, select 1920x1080 that should give you a good scale ratio on the Yoga Pro 2.

In UbuntuGnome 14.10 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 change reboot the laptop, this will enable wifi and bluetooth.

What works

Almost everything works great out of the box in UbuntuGnome 14.10, there isn't many changes you need to do.

Sound works

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


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


Works fine.


No issue.


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

Fn key to show all screens, the side mute button, Fn key to disable track-pad function, Fn key to enable air-plane mode function.

HiDPI support

UbuntuGnome 14.10 supports HiDPI by default, no changes required.

Tweaks to make some Apps work better with HiDPI 

Open Firefox advanced preferences page (about:config) and set parameter layout.css.devPixelsPerPx to 2 (or find the one that suits you better; 2 is a good choice for Yoga Pro 2 screen)

If you use a HiDPI monitor such as Yoga Pro 2 display together with another monitor, you can use AutoHiDPI add-on in order to automatically adjust layout.css.devPixelsPerPx setting for the active screen. Set Pixel Ratio to 2x and HiDPI screen with to 3200, on the plug-in settings page.

If you use the touch screen you should install Grab and Drag add-on 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.

Run chromium at device scale in case it starts with big fonts.

chromium-browser --force-device-scale-factor=1 

Cheese and totem work great in HiDPI, but VLC and Clementine still show interface with icons that are not scaled properly, see below.

USB 3 ethernet adapter

I got a USB 3 Ethernet adapter at frys, it works great.

I'm also using a SIIG USB 3 hub with power adapter to plug a logitech USB sound bar, the USB 3 Ethernet adapter, a wireless mouse dongle and a external disk 60 Gb SSD.


Intel Video drivers [not recommended]

Follow the link https://01.org/linuxgraphics/downloads.

# Download "Graphics Installer 1.0.6 for Ubuntu* 14.04, 64-bit"
sudo dpkg -i intel-linux-graphics-installer_1.0.6-0intel1_amd64.deb

You can scale the screen using
xrandr --output eDP1 --scale 0.7x0.7

Wifi network card upgrade [not recommended, only do it if you need dual band wifi]
