Screenshot on Android

Do get a screenshot, run in a shell:
  adb shell screencap -p /data/tmp.png
  adb pull /data/tmp.png

Enable reverse tethering on Nexus 4/Ubuntu phone

First we'll activate the usb-networking on the phone:
  adb root
  adb shell setprop sys.usb.config rndis,adb

Note: If you get "error: insufficient permissions for device" trying to adb after this line, this is probably due to an udev bug. You can workaround it by
  adb kill-server
  sudo adb start-server

Wait until NetworkManager on your computer shows the new connection. (It will say "disconnected" after some time). Edit the connection, and change under "IPv4 Settings" the method from "Automatic" to "Shared to other computers". Reconnect that connection in NetworkManager.

Then log into the phone via ssh (important!) and run

  dhclient usb0 -v

Now you can check on the phone, if it works
   ping google.com
