Ubuntu users have been clamoring for a way to move the Unity launcher to the bottom of the desktop. Well, Ubuntu user Paullo has created an unofficial Compiz plugin that does just that!
The launcher has all the same configurability features as the regular launcher, minus a few quirks/bugs. As you see in the screenshot below, the dash looks a little out of place because it is not up against the top panel. Having the dash full screen fixes this.
*** NOTE: Huge FYI, this is for 32-bit systems ONLY at the moment. Paullo is still working on a 64-bit version. If you have a 64-bit system, DO NOT proceed. I did and broke my Unity. ***
The Compiz plugin can be downloaded from here.
To be able to extract it, you will need to install lzma. This can be done via the terminal:
sudo apt-get install lzma
Extract the downloaded package to your home folder. There should then be a folder called “unityshell” there.
Finally, run the following commands in the terminal, one line at a time:
mkdir -p ~/.compiz-1/plugins
cp libunityshell.so ~/.compiz-1/plugins/
cp *.png /tmp/unityshell/
chmod 644 *.png
sudo chown root:root *.png
sudo cp *.png /usr/share/unity/4/
Once you have run all those commands, log out and log back in. The launcher will then be moved to the bottom of the desktop.
To revert back to having the launcher on the left of the desktop, run this command:
Log out and log back in and it will be back on the left.
