Description

Configuration and usage of multiple monitors with KDE.

Setup

Obtain a multihead configuration (Laptop LCD + at least one external monitor or multiple monitors), have only one display connected at first.

How to test

  1. Positions
    1. Log-in to the KDE session and following that connect all the remaining monitors. Run SystemSettings and go to the Display and Monitor module. Choose to enable all monitors by selecting an 'Auto' size for their resolution. Select the display that appears rightmost to be the 'Primary output'. Apply and accept the configuration.
    2. Now set the position of your currently rightmost display to "Left-of" your current leftmost display, apply.
    3. Now change the position of the primary display to Absolute and the position of your now rightmost display to Above or Below the primary one. If you have three or displays, try to make an 'L' looking screen with them.
    4. Choose one of your displays - and have all others "clone" it.
    5. Set 'Position' of all displays to Absolute and have them positioned apart from each other.
  2. Orientation
    1. Now set an 'Orientation' of all monitors to a different value. I.e. one to left, one to right, one to upside down etc.
    2. Using the 'Orientation' menu, have one of your displays 'Mirror vertically' and the other to 'Mirror horizontally'.
  3. Other
    1. Feel free to try all the other options present in the SystemSettings configuration too - these should always behave to the output you expect.

Expected Results

  1. Positions
    1. Screen should now cover both displays allowing you to transfer mouse seamlessly between them. The main panel - the one with the kickoff menu and the tray area should be present on the rightmost monitor.
    2. Your rightmost display is now your leftmost mone - while still keeping the primary panel.
    3. Displays are positioned vertically or into 'L' - overall screen including mouse transfers still works seamlessly.
    4. All displays show the same simple screen. Resolutions may get scrambled.
    5. All monitors display a separate part of screen, moving mouse from one to the other results in mouse going through a 'gap'.
  2. Orientation
    1. Displays are all rotated as expected, having no impact on working of the screen as a whole.
    2. In both cases the picture is flipped, vertically and horizontally.
