{{From|https://help.ubuntu.com/community/XubuntuPanels}} {{Languages|UbuntuHelp:XubuntuPanels}} == Introduction == This page provides guidance for restoring and fixing the top and bottom panels when using Xubuntu Desktop Environment. Since disappearing panels occurs often, this page will help restore the panels. Some of this information is available to the user in /usr/share/xfce4/doc/C/xfce4-panel.html. To help the developers find the causes of the panel disappearing, you can file a bug report before restoring the panels. Please try to obtain the appropriate logs as requested in [[UbuntuWiki:Backtrace|Debugging|Procedures]]. == Quick Fix == This requires you to log out and log in again. <pre><nowiki> Alt+F2 (run window) rm -rf ~/.cache/sessions (delete the Xfce4 saved sessions files for your user) Click on "Run" (or hit the enter key) </nowiki></pre> Now you will log out and log in again. Make sure "Save session for future logins" is not checked. If the '''Quick Fix''' fails, please try the next method. == All Panels Disappeared == If the xfce4 panels do not start with your desktop session, use <pre><nowiki> Alt+F2 (run window) xfce4-panel (command to start panels) Click on "Run" (or hit the enter key) </nowiki></pre> It is not necessary to use gksu / sudo. When you finish your session, be sure to put a check on "Save session for future logins". This will insure you have panels when you restart. == One Panel Disappeared == If there is a single panel or a partial panel, press <pre><nowiki> alt+f2 (run window) killall xfce4-panel (command to kill the panels) Click on "Run" (or hit the enter key) alt+f2 (run window) rm -rf ~/.config/xfce4/panel/ (delete the Xfce4 panel's config files for your user) Click on "Run" (or hit the enter key) alt+f2 (run window) cp -r /etc/xdg/xfce4/panel ~/.config/xfce4/ (copies existing default file) Click on "Run" (or hit the enter key) alt+f2 (run window) xfce4-panel & (command to start panels) Click on "Run" (or hit the enter key) </nowiki></pre> When you finish your session, be sure to put a check on "Save session for future logins". This will insure you have panels when you restart. == Any Item Disappeared From The Panel == If only one item disappeared from the panel, try adding it back: * right-click the panel * left-click "Add New Items..." * left-click the item to be added * left-click the 'Add' button The Applications Menu is listed as Xfce Menu. When it is added, you can change the "Button title"; it pre-fills as "Xfce Menu"; change it to "Applications". You can then click 'Close' and the menu is added. Right-click the menu, left-click "Move", and move it to the left side of the screen if you want. [[category:UbuntuHelp]]
