Comment 3 for bug 1308645

1. Reset using compiz manager (ccsm-settings-reset on typical),

  I am not familiar with this tool. We do not support problems with third-party tools.

2. remove config files:
gconftool-2 --recursive-unset /apps/compiz-1
gconftool-2 --recursive-unset /apps/compizconfig-1
unity --reset
rm -rf ~/.config/compiz-1/compizconfig/*

  You have manually wiped out your Compiz configuration and consider it a bug that your Compiz
  configuration has been wiped out? If you break it on purpose, you get to keep both pieces.

  Note that "unity --reset" is not an available command in Ubuntu 14.04.

3. unity-tweak-tool --reset-unity

  We do not support problems wit third-party tools.

  I suggest you reset you Compiz configurations to their original default values using the following command.

    dconf reset -f /org/compiz/

  Please try this and let us know if it works for you.
