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:
After a reboot Wifi and Bluetooth should work.
Sinces Ubuntu 14.04.1 this fix doesn’t seem to be necessary. For the sake of completeness I leave it here.
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:
Option “Backlight” “intel_backlight”
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.
First the dependencies:
sudo apt-get install python-appindicator notify-osd
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”:
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
I use xbacklight to controle the brightness on startup:
sudo apt-get install xbacklight
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 😉
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.
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.
