Ubuntu – Running Xubuntu without panels

I had this problem after I changed graphics drivers. My solution was:

1. Press Alt+F2.

2. Type xfce4-panel --preferences and press Return. This brings up the panel preferences.

3. Under Output, make sure that it is selected to show up on the right monitor. It might be selected to show up on an external video output or some other non-existing monitor.

4. Repeat this for all affected panels by selecting them from the pull-down at the top of the panel preferences window.
