Displays overlapping on Kubuntu 20.04 on Asus ZenBook with Nvidia GPU

The problem ScreenXpert overlaps the main screen when Nvidia MX250 is chosen as main graphics card. The same thing doesn't happen with Interl graphics as primary card.

The solution is to disable the ScreenXpert monitor before the welcome screen loads. In order to do this, open the file /usr/share/sddm/scripts/Xsetup in an editor and at the end add the following line:

xrandr --output HDMI-1-2 --off

Running Zenmap on Ubuntu 20.04

  1. Download Zenmap packages and convert rpm packages to deb as described here.
  2. Install python 2.x by running

    sudo apt-get install python

    If you try to run Zenmap now, you'll get the following error:

    Could not import the zenmapGUI.App module: 'No module named gtk'
  3. Download the following packages from Debian repositories:
  4. Install python-gobject-2, then python-cairo and then python-gtk2.

    You may need to fix dependency problems by running

    sudo apt --fix-broken install.

  5. Enjoy Zenmap!
