Hello all, I gave up :)
Unfortunately but current state of Displaylink driver or Xinerama is unusable for me with Awesome and pretty any WM (including KDE). The only one working was XFCE but this is not what I want. I will keep trying and if I find it working for me as I want I will report. Thank you all for your kind support. With kind regards.
