Lenovo Yoga 2 11 – english

OLYMPUS DIGITAL CAMERAThe original German post can be found here.

Lenovo Yoga 2 11

In response to the great demand, I actually decided to translate this little article.

The Lenovo Yoga 2 11, needs some tweaks to make it compleatly usable with Linux. As OS I’m running Ubuntu (Trusty), as Unity still remains the only full-touch-screen-supported User-Interface, that can be used for normal office work. Of course there are other great User-Interfaces for Linux, but mostly the developers aim for tablet support without mouse & keyboard.

According to the Hardwar Maintenance Manual there are different chips, hard-drives and other hardware build into the Yoga 2 11. For example there are 2 different Wlan/Bluetooth-cards build into different models. One made by Intel, one by Broadcom.

How to make the Laptop Yoga 2 11 usable with Ubuntu?

Wireless & Bluetooth

By default Ubuntu recognizes this Chip as “deaktivaded by hardware switch”. That’s why “ideapad_laptop” needs to be blacklisted. With

sudo nano /etc/modprobe.d/ideapad_laptop.conf

you make the file /etc/modprobe.d/ideapad_laptop.conf. Insert the content:

blacklist ideapad_laptop

After a reboot Wifi and Bluetooth should work.

Brightness-Hotkeys

Sinces Ubuntu 14.04.1 this fix doesn’t seem to be necessary. For the sake of completeness I leave it here.

Brightness

By default the brightness runs at full capacity, which can not be changed. This drains the battery an it lasts only 2 to 2.5 hours. To fix this make the file: /usr/share/X11/xorg.conf.d/20-intel.conf with

sudo nano /usr/share/X11/xorg.conf.d/20-intel.conf

Insert this content:

Section “Device”
Identifier “card0”
Driver “intel”
Option “Backlight” “intel_backlight”
BusID “PCI:0:2:0”

EndSection

After a reboot all hotkeys work. Including F6 und F7, even if they have no default configuration, but you can set one .

ETPS/2 Elantech Touchpad

Multitouch is not working? Probably you have a ETPS/2 Elantech Touchpad.  See here. Sorry I can not provide further help, I got the other one.

IndicatorAppindicator

First the dependencies:

sudo apt-get install python-appindicator notify-osd

All nessesary files can be downloaded here.

Unzip the Tarball to your home-directory and make the files executable :

tar xfvz Yoga-Modes.tar.gz

chmod +rwx .Yoga-Modes/ -R

the folder ~/.Yoga-Modes contains single files, which are executed by switching modes.

Explination with the example “Laptop”:

#!/bin/bash
xrandr –output eDP1 –rotate normal  ##screen-rotation
xinput set-prop „Atmel Atmel maXTouch Digitizer“ „Evdev Axes Swap“ 0 ##swap touchscreen
xinput set-prop „Atmel Atmel maXTouch Digitizer“ ‚Evdev Axis Inversion‘ 0 0 ##rotate touchscreen
xinput set-prop „SynPS/2 Synaptics TouchPad“ „Device Enabled“ 1 ##turn on touchpad 
echo 2 > .toggle ## save mode for toggle script
notify-send -i ~/.Yoga-Modes/icons/Open.png „Laptop“ ## show notification
killall onboard ##kill onboard 

 

Add tis to StartUp-Applications:

/home/user/.Yoga-Modes/Indicator        ##user needs to be changed

 

Energie

I use xbacklight to controle the brightness on startup:

sudo apt-get install xbacklight

In Autostart:

xbacklight -set 20

Furthermore I use TLP to controle to remaining hardware in backbround.

sudo add-apt-repository ppa:linrunner/tlp

sudo apt-get update

sudo apt-get install tlp tlp-rdw smartmontools ethtool

With this tweaks the battery hold for 3 lectures á 2 hours writing Latex and it still runs. So seven to eight hours office-work are realistic with activated wifi and deactivated Bluetooth. But still the biggest energy guzzler is the screen-brightness, so take off your sunglasses 😉

Improve Wifi-Signal

OLYMPUS DIGITAL CAMERA

The Wifi-Connection is not the very best on Windows and on Linux. Extending the antenna does help. In the right circle there is the Wifi/Bluetooth-Chip. From there 2 cables (one black, one white) run around the batteryto the left circle. Soldering 3cm (about 1 inch) cable to each of the black and white cable improved the connection a lot for me.

Do not do this if you don’t know what you are doing. I do not guarantee for anything, if you follow this advice you do it on your own risk. And you deftly will void your warranty.

SSD ?

See here.

This laptop comes with different HDDs. Mine is the wd5000mpck. It got a proprietary plug called “SFF-8784 edge connector”, same with the wd5000m22k. I haven’t found any SSD with this plug yet. So make sure you get a model with the ST500LT032 HDD, so you have a normal SATA-connection.

If have further questions you can write me an e-mail or comment below.
