How to run any X11-app on ubuntu-touch?

Ubuntu touch preview does not use X11 for graphics. The repository for armhf contains virtually all apps available in desktop Ubuntu, but they cannot be run directly on the tablet (Nexus 10 in my case).

Is there a way to run those using a virtual X-server, perhaps passing through local VNC to be displayed? I have ssh access to the device, so I can run commands normally.

You can also run it on the phone via XMir. You need to create a custom launcher for your X11 application, let's say it is called my_x11_app, and the desktop file is ~/.local/share/applications/my_x11_app.desktop, looking like this:

 [Desktop Entry] 

 Name=My X11 App

 X-Ubuntu-Touch=true 

 X-Ubuntu-XMir-Enable=true 

 Exec=/path_to_my_app/my_x11_app

 Icon=/path_to_my_app/my_x11_app.png

 Terminal=false 

 Type=Application

if you cannot see the app icon on the phone among other apps, just use the search feature, it will rescan launchers and after that the icon will be there.

Additionally, if you need an on-screen keyboard support in the x11 app there are 2 conditions you need to fulfill:

you need to install maliit-inputcontext-gtk3 and maliit-inputcontext-gtk2 packages into your ubuntu phone

you may need to set environment variables in your app, at least export GTK_IM_MODULE=maliitphablet

I wrote an article about this on my blog: http://kriscode.blogspot.tw/2016/09/x-applications-on-ubuntu-phone.html

Alternatively you can install Libertine and use your x11 app with it.
