ubuntu touch on a lenovo yoga 3 pro



  • Hi everybody,

    Marius mentioned the desktop version during the community update 20.
    I would like to install it on my laptop (with a freshly installed xenial on it, as a starting point), but didn't find anything on the docs or elsewhere.
    I added a ubports.list to /etc/apt/sources.list.d and upgraded:

    sudo echo "deb http://repo.ubports.com/ xenial main" > /etc/apt/sources.list.d/ubports.list
    wget -O - http://repo.ubports.com/pubkey.gpg | sudo apt-key add -
    sudo apt-get update
    sudo apt-get upgrade
    sudo apt-get dist-upgrade

    Can someone tell me, what else must be done?





  • @hummlbach looking forward to hearing about your experience



  • Here are my first impressions and observations.
    The following was working out of the box:

    • All the special keys on the hardware keyboard
    • Hardware keyboard is disabled when flipped on the back of the screen (done in hardware(?), but not the touchpad)
    • touch, edge gestures
    • pretty much all the manual settings

    What is not yet working and what I want to fix/implement: :)

    • Onscreen keyboard (the only thing in this list I actually expected to work, ubuntu-keyboard was missing, but after installing it, it still does not show up, not even when touching on the keyboard icon in the terminal app - any ideas?)
    • Automatic screen rotation
    • Automatic adaption of the brightness
    • Automatic toggling of desktop mode depending on the flip state of the hardware keyboard
    • browser (perhaps I was expecting that to work too ;))
    • since the native screen resolution is 3200x1800, everything is displayed way too small


  • The first thing i wanted to fix, was the heigh dpi resolution problem. I found the solution for the unity8/mir stuff by putting 'export GRID_UNIT_PX=24' in ~/.profile and for x11 apps I added the option -dpi 42 in /usr/bin/libertine-xmir. But while the first is working as expected, the latter seems to have no effect. (tested with chromium among others) Is this a known bug? (Since I'm tried to open libreoffice, the x11 apps do not work anymore at all... :-/ reboot didn't fix it.)



  • @hummlbach try this: echo "Xft.dpi:220" > ~/.local/share/libertine-container/user-data/vivid/.Xdefaults

  • I don't know what I've done to spoil it, but I assume it was an apt-get upgrade approximately one month ago...
    Since then I'm not able to start X11-apps anymore... To figure out what is happening, I've started XMir manually and launched chromium from the console as follows:

    XMir is crashing as soon as I'm trying to launch an X-application (so the last line appeared, when I've did the following):

    $ export DISPLAY=:1
    $ libertine-launch /usr/bin/chromium-browser
    ATTENTION: default value of option force_s3tc_enable overridden by environment.

    Is this a known issue? Anyone ran into it already?

    I've gotten into screwed-up states with apt-get upgrade. I'd suggest you flash again and start over
