Do you use the terminal a lot in Linux? With only Compiz Fusion and Gnome-Terminal you can have a transparent terminal that looks like it is part of your desktop. (See the screenshot at the end of this post.) I found the idea for this over at Ubuntu Unleashed, my instructions here are slightly different.
You need to create a new gnome-terminal profile for the transparent terminal. Create a new profile in Edit>Profiles>New called trans. Edit the new profile and set these options:
Open the CompizConfig Settings Manager and make these changes:
The transparent terminal should start with this command:
I tried to set up the terminal to start when I log in, but ran into a problem. The terminal would load before Compiz Fusion, which causes it to not be positioned properly. I created a script to launch the transparent terminal:
It delays for 10 seconds, and by that time Compiz Fusion is loaded. Just run the script on login with System>Preferences>Sessions and it should work.
