I'm running xubuntu 18.04. I recently switched from a triple-monitor setup to single monitor -- and now the xfce panel and the whisker menu don't show up on the desktop. I can seexfce4-panel in the process list, I just think that it's displaying on a screen that doesn't exist. Not sure how to fix this, since I can't click on the panel to unlock and re-position it.


Following Terrance's lead, I opened xfce4-settings-manager, but then opened Panel instead of Display.

I had previously set Output to Monitor 2, which did not exist. I set this to Primary, which fixed the problem.

  • You can have the answer. I didn't even think about checking the Panel itself to make sure it was set to the primary monitor. Good find! =) +1 – Terrance Apr 8 '20 at 19:10
