Ubuntu GNOME 16.04 running on Yoga Pro 2 with HiDPI and touch screen support

Ubuntu GNOME 16.04 running on Yoga Pro 2 with HiDPI and touch screen support








See my previous post on how to install Ubuntu on Yoga Pro 2 for Ubuntu GNOME 15.10.

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

Ubuntu 16.04 is not released yet, the screen shoots are from a daily build, 16.04 it is scheduled to be released in Q2 2016.

Touch support

Ubuntu gnome support for touch screen is pretty good on the desktop shell.
Chrome browser supports touch screen very well and much better than Firefox without any plug-ins.
The windows key on the screen panel works as the windows key on the keyboard.
Screen rotation is supported on the new gnome and disables the keyboard when the yoga is used as a tablet, but sometimes screen does not rotate, I'm still trying to figure out what is wrong.

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 supports UEFI out of the box.

I also enabled the Functions keys in the BIOS by default but this is a 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.


 

Install

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 the drives.

Select the partition size for Ubuntu let the Ubuntu Gnome installer re-size your windows partition. Grub will have an option to boot windows after the install is done and will setup Ubuntu as the default OS.

Note:
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 3.18 and will boot with full resolution HiDPI and touch screen support enabled.

What works

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

Screen HiDPI support

Everything works, brightness, resolution changes, even the option keys to turn off the screen and brightness. Video driver works great.

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

Reference for other applications on HiDPI:
archlinux HiDPI documentation

Camera, Sound, Keyboard, Sleep, Wifibluetooth, USB3 works

Camera, sleep, wifi, Bluetooth, USB3 and side sound button up/down worksKeyboard background light works, Special Fn key mute, volume up, volume down, turn off screen, refresh, brightness up and down, menu key, keyboard light, air-plane mode, all work as expected. The windows touch logo on the touchscreen works.

Fn key to show all screens works but it is a shortcut to Activities menu so you don't have to use the touch pad.

Does not work out of the box

The small side mute button, Fn key to disable track-pad function.

Tweaks to make some Apps work better with HiDPI 


Firefox, Google Chrome, Chromium, Cheese, totem, vlc work great in HiDPI.

sudo apt-get install google-chrome-stable

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/Chrome  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=2

For Thunderbird see Firefox. To access about:config, go to Edit → Preferences → Advanced → Config editor.

Skype is a Qt program, and needs to be configured separately. You cannot change the DPI setting for it, but at least you can change font size. Install qt4 and run qtconfig-qt4 to do it.

Clementine still show interface with icons that are not scaled properly.

Console

Configure larger font on tty console, leave all settings as they are, but for font select Terminus, and on the last one, where you can chose the size 16x32, and then reboot.

sudo dpkg-reconfigure console-setup

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.

Links to the hardware:

Intel Video drivers [not recommended]

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

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


I also upgraded the wifi network card to a intel dual band, link to amazon and Youtube video.

Spec: 7260NGW Intel® Dual Band Wireless-AC 7260 802.11ac, Dual Band, 2x2 Wi-Fi + Bluetooth 4.0

sudo lspci -v
01:00.0 Network controller: Intel Corporation Wireless 7260 (rev 6b)    Subsystem: Intel Corporation Dual Band Wireless-AC 7260
    Capabilities: [154] Vendor Specific Information: ID=cafe Rev=1 Len=014
    Kernel driver in use: iwlwifi

Works great.
