Unity is misbehaving after installing GLX Dock - HUD does not open with GLX Dock turned off and there are ugly shadows in the panel, three control buttons (close, minimise, maximise) and "Ubuntu Desktop" label when there are no apps running. I have to click the top panel to get the Super key to open the Dash.

I have tried unity --reset and unity --replace commands, but they do not help.

Can I un-install and re-install Unity?

This is what I used when I had a problem with it.

These Commands Will Remove/Uninstall Compiz Unity:

sudo apt-get remove compizconfig-settings-manager
sudo apt-get remove compiz-fusion-plugins-extra
sudo apt-get remove compiz-plugins-extra
sudo apt-get purge compiz*

Then to Re-install Compiz Unity use:

sudo apt-get install unity-2d
sudo apt-get install ubuntu-desktop
sudo apt-get install ubuntu-desktop-2d
sudo apt-get install compizconfig-settings-manager
sudo apt-get install xserver-xgl
sudo apt-get install emerald
sudo apt-get install compiz-fusion-plugins-extra
sudo apt-get install compiz-plugins-extra
sudo apt-get install unity

    can you explain what you are doing, and why it works? –  Mar 13 '13 at 01:06
  • As you can see by the command line code in the "Use this to Remove/Uninstall Compiz Unity:" it is Uninstalling Compiz Unity, so if there was any bugs or Problems before hand it has now been wiped, so you can do a new install to fix the corrupted Compiz Unity files if it had a problem before. – Mattlinux1 Apr 26 '13 at 16:14
  • You can combine those apt-get install and apt-get remove lines. – NoBugs Aug 10 '13 at 00:23
  • While reinstall I am getting the following error! Reading package lists... Done Building dependency tree
    Reading state information... Done E: Unable to locate package ubuntu-desktop-2d E: Unable to locate package xserver-xgl E: Unable to locate package compiz-fusion-plugins-extra     – Cyril Jan 21 '15 at 12:34
