I'm using 64 bit Lubuntu 15.04, I inserted my monitor, opened arandr
, activated the monitor and positioned it as shown below. Now the problem I'm having is that my monitor seems to be considered the main screen as it has my desktop icons and task bar. Now how do I move the bar (and the icons) to the bottom (laptop) screen?
just drag and drop the monitor you want to make it as the default monitor to the first position then drag the other to be beside and not down, then press save
It seems the monitor where the task bar is positioned at, can be changed in the task bar's panel preferences. To the right you can see the monitor it is displayed at. Change the number to 2 and it changes monitors. This does not reposition your Desktop icons though.
Right click the task bar and click
Panel Settings > Geometry
to get to the preferences pane.
