I was running Ubuntu 16.04 on a Lenovo laptop; I had CCSM installed and the Negative plugin enabled, which allowed me to use a keyboard shortcut (super+n) to invert the colors on any given window. After upgrading to 18.04, CCSM still shows that the plugin is enabled, but the keyboard shortcut doesn't do anything.
