Rebooted my PC today to find that my launcher icons are not showing on the launcher bar, even though they are still there. I can hover over the launcher bar and see (via the mouse tool-tip) that they are still there, and I can even interact with them. I cannot, however, see them even after doing the following:

• Trying to reset unity via unity --reset


• Attempting to remove and re-install Compiz Unity via these instructions: How can I remove and re-install Unity?.
