I don't know what changed on the system to cause this. If I run 'ps auxw | grep panel', I can see that the process is running. If I kill the running process, the panel appears very briefly before it exits. If I run it from an xterm, I get this error when I first execute the command: (xfce4-panel:4132): Gtk-CRITICAL **: gtk_container_remove: assertion `GTK_IS_WIDGET (widget)' failed If I then kill the panel, this comes out just as it becomes briefly visible: (xfce4-panel:4132): Gtk-CRITICAL **: gtk_container_remove: assertion `GTK_IS_WIDGET (widget)' failed ** Message: xfce4-panel: Exit Reproducible: Always
sorry - this is on an up-to-date FC5
I'm afraid I have no idea what could be the problem here :( I'm wondering if perhaps one of the plugins is blocking the panel. Maybe you could try using the default panel layout. To do this rename the ~/.config/xfce4/panel/contents.xml file (make sure the panel is not running) and start the panel. Does that make the panel start properly?
Created attachment 901 current panel contents This is the panel configuration I have now. I did try moving it aside and letting the default configuration take over - it still doesn't show.
I think I have a useful clue - the problem only occurs when I'm running two X displays. At my office, I dock my laptop and the dock has an external monitor attached. The X startup detects that and runs a second display (They are :0.0 and :0.1). When in this mode, the panel does not appear on either display. When I boot my laptop out of the dock so that there is only one X display, it appears normally.
Created attachment 904 The attached xorg.conf file is taken from when the system is being run with two displays, and the panel does not show
- What are the resolutions you are using? - When you maximize a window, what happens? Does it maximize normally? - Can you open the panel properties dialog when the panel is not visible (from the xfce-mcs-manager or xfce4-panel -c)? Some notes on your xorg.conf file: - Why is Clone on? - You should also Add 'Screen 0' to Videocard0. - Xinerama should be in the "ServerFlags" section.
Any news on this?
Long time no new and a 3 year old bug.
