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?

Ah, I found:

Thanks a lot!

@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

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
