After upgrading my Xubuntu to 12.10, the panel icons are visually broken (but functional), see screenshot. Some of the buttons are displayed as a purple gradient. Exactly which buttons are drawn this way varies as the mouse is moved over them, and usually the button under the mouse pointer is drawn correctly. Any ideas about what is causing this?

Well, you could try to reload XFCE.

XFCE stores it's configuration for the running session in xfconfd. Feel free to back up the files you're going to delete first.

  1. Shut down the panel first, xfce4-panel --quit
  2. Kill the xfce4 configuration daemon, pkill xfconfd
  3. First delete settings for the panel, rm -rf ~/.config/xfce4/panel
  4. Clear out the settings for xfconfd, rm -rf ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-panel.xml
  5. Restart the panel, run xfce4-panel. This will respawn xfconfd automatically. Note if you need or want to restart xfconfd manually know that on my installation it was in /usr/lib/x86_64-linux-gnu/xfce4/xfconf/xfconfd which was outside of $PATH.

This clears the running session, regenerates the files, and then it sets it default for future sessions.

Hope this helps!

Ouch. I was hoping for a answer little less "shotgun-like". – JesperE Mar 14 '13 at 7:44
