    Same happended to me. But, first of all, after I upgraded to 14.04 I didn't have this problem, it happened like two days ago after an update. The point is that I solved it by applying a solution I once knew worked for 13.04. Its the following:

    • Run the dconf-editor:

      $ dconf-editor

      (if you don't have it install it by: sudo apt-get install dconf-tools)

    • In the pop-up window go to the list on the left and open "core", which you find in the following order:

      org -> compiz -> profiles -> unity -> plugins -> core

    • Once selected "core", on the right find a key named "active-plugins", and change the order of the last three entries in the "Value" field, so that the last ones are 'unityshell', 'expo' and 'scale'. For ease of the procedure, delete all the entries in the "Value" field, copy the following lines and paste them in the "Value" field:

      ['core', 'composite', 'opengl', 'copytex', 'compiztoolbox', 'resize', 'mousepoll', 'wall', 'widget', 'grid', 'imgpng', 'snap', 'move', 'place', 'regex', 'vpswitch', 'animation', 'session', 'unitymtgrabhandles', 'workarounds', 'fade', 'ezoom', 'unityshell', 'expo', 'scale']

    • Reboot.

  2. Hi guys I am very new to Linux (less 24 hours) but I've already met with this problem and found a solution.

    Go to Startup Applications then ADD a new one, give it a name (doesn't matter what) and add this command:

    compiz --replace

    Then save. restart and enjoy.

    Edit> doesnt work reliably, though.

  3. in 14.04 for a work around what I did was write a bash script to set the hot corner edge valuse using dconf, but you will need to use dconf to find out what hot corner triggers you are using you need to install dconf-editor, using the tree-structure you can work out the paths.

    #!/bin/bash
dconf write /org/compiz/profiles/unity/plugins/scale/initiate-edge "'|TopLeft'"
dconf write /org/compiz/profiles/unity/plugins/scale/initiate-all-edge "'|BottomLeft'"
dconf write /org/compiz/profiles/unity/plugins/expo/expo-edge "'TopRight'"
dconf write /org/compiz/profiles/unity/plugins/core/show-desktop-edge "'|BottomRight'"

    For expo it didn't have | in front

    Then I ran this automatically script after logging in, by adding it via "Startup Applications" you have to search for it in Unity Dash.
