2 Answers. Alt-F4 is the windows command to close an application. The application itself has the ability to execute code when ALT-F4 is pressed.

How do I restart Xfce desktop?

Sadly, there's no built-in way for XFCE users to click a button so that the panel will restart, and there's no secret reset function built-in like there is in Gnome Shell. Instead, users looking to fix a non-responsive XFCE4 panel must force-quit it and re-launch it.

How do you restart Lxpanel?

Re: How I refresh lxpanel

I believe it has something to do with an overflow when the TaskBar has too many icons to display, but this is unconfirmed. As daniel said, the easiest solution is the RestartPanel command, i.e, [Alt+F2] lxpanelctl restart.

How do I restart my mate panel?

Re: Restart the desktop in Mate

Ctrl+Alt+F7 (or F8 for older installations) will return you to your GUI desktop. F5 should refresh your lost desktop. If not, Ctrl+Alt+Backspace, Backspace will return you to the GUI login screen where the desktop will correct itself after login.
