My system is Lubuntu, freshly installed, and has been working fine for a couple of days.

I don't know since when, but when I press Alt+Tab I cannot see my task switcher. Instead, some window border is highlighted. But neither the window content, nor the application icon is provided, it is useless for task selecting.

How can I get the original task switcher back?


It's strange that this setting would change out of its own accord but you should be able to revert it by manually editing the configuration file of your window manager (openbox):

  1. Create a backup copy of your existing openbox configuration:

    cp "~/.config/openbox/lubuntu-rc.xml" "~/.config/openbox/lubuntu-rc-old.xml"
  2. Open ~/.config/openbox/lubuntu-rc.xml in a text editor of your choice

  3. Find the section in your configuration file corresponding to the following snippet:

    <keybind key="A-Tab">
      <action name="NextWindow">
    <keybind key="A-S-Tab">
      <action name="PreviousWindow">
  4. In both instances, replace <dialog>none</dialog> with <dialog>list</dialog> (vertical list of window icons and window titles) or <dialog>icons</dialog> (horizontal list of window icons)

  5. Update your current openbox session by executing openbox --reconfigure

    OP should also back up lubuntu-rc.xml first, and then, after editing as you've suggested, run openbox --reconfigure from a terminal to get the changes to take effect. Otherwise, a logout, login or a restart of Openbox is required. The nice thing about openbox --reconfigure is that it does a bit of "parsing" and let's you know if it finds something smelly. – DK Bose Aug 19 '14 at 2:13

    @DKBose Ah, yes, completely forgot about reconfigure. Thanks for the pointer! – Glutanimate Aug 19 '14 at 2:14

    No problem! Nice to see you helping out Lubuntu/Openbox users. I've started using Lubuntu and quite like it. Sometimes, I even choose the Openbox session at login time. – DK Bose Aug 19 '14 at 2:21
