Description Ismael Castiñeira Álvarez 2015-10-23 18:24:31 UTC

I have configured a panel in the right border of the screen (laptop), with auto hide. 
When connecting an external monitor (side by side), the panels moves to the external monitor. When removing the external monitor, the panel does not come back to the main screen.

Plasma shows the correct number of the panel's widgets in the "Add widget" window, but the widgets are *dead*. That means that the network manager applet won't auto connect to wifi networks, KDE Connect won't start, volume keys don't work, notifications are shown as boxes.

When connected the external monitor, the panel will appear and all widgets will start working. 

Reproducible: Always

Steps to Reproduce:
1. Have a panel autohiding in the right border of the screen
2. Add an second display and set up to the right (KScreen will do that for you when cycling through screen configs). The panel will move to the new screen.
3. Disconnect the second display.

Actual Results:  
Goodbye panel. It does not come back unless you connect the external panel again. 
Restarting plasma does not fix this.

Expected Results:  
The panel should come back to its position, where it was before the secondary monitor was connected.

Comment 5 raay.max 2016-01-11 02:27:51 UTC

I have similar problem.
When I connect second monitor - panels moves to external screen. When im trying to move them back they dissipaters. When I try to disconnect and then reconnect monitor panels sometimes shows back on external monitor but I cant move them back to my primary laptop screen. Only way is to recreate panel.

My config:
I don't use auto-hide. 
Only one panel in default location.
External screen on left of laptop.

Reproducible: Always 
Steps to Reproduce: 
1. Connect second monitor
2. Disconnect second monitor

Actual Results: 
No panels on primary screen.

Expected Results: Panels should stay on their places when connecting anything, My dreams are to remember panels and widgets for specific screen - sometimes I use 2 external monitors and laptop screen and I want to configure widgets and panels on them only once. Now i have to reconfigure everything every connect or disconnect of screen.  Moving panels through screens should work.
