Bug Description
XUbuntu displays the desktop icons and main taskbar (xfce4-panel) on the left monitor in a dual-monitor configuration, even if you go into the "display" control panel and mark the right-side monitor as "Primary Display."
Hardware: one monitor is connected to an HPE ProLiant Micro-server via its VGA port, and the other monitor is connected to a DisplayPort-to-VGA adapter that is in one of the Display Ports.
Operating system is Xubuntu 19.10:
$ lsb_release -rd
Description: Ubuntu 19.10
Release: 19.10
To reproduce: startup the computer. Go to the "display" app. Order the displays in the "display" app, then click on the right-side display, then click the switch icon next to "primary display" to toggle the right-side display to be primary.
Actual behavior:
The main taskbar (Xfce Panel) with the Whisker Menu remains on whichever monitor is designated as "left" in the Display app, even if the right display is designated as "primary."
Desktop icons display on the left monitor, even if the right display is designated as "primary."
Some programs open on the left monitor; others open on the right monitor.
This is very similar to the behavior documented in bug #1425000 which is marked as "won't fix," but the notes in bug #1425000 say that if the behavior is observed in xfce4, then a new bug-report should be opened. (Only difference is that in bug #1425000, which pertains to the Unity environment, programs always open on the left side. Here they may open on either monitor.)
Expected behavior:
Main taskbar (Xfce Panel) with the Whisker Menu should be on whichever display is selected as "primary" in the "display" app.
Desktop icons should, by default, display on whichever monitor is selected as the "primary" one.
Programs should open, by default, on whichever display is selected as "primary."

i am on debian stretch/xfce4 with triple monitor setup and no matter where i try to set the primary display, xfce ignores it. Windows/ Applications are generally openend at the left screen, even though the primary screen is set to the middle. The only time they are not opened on the left is, when they are set to be opened on the screen where the cursor currently is. This behavior can't be correct.
