How can I change the transparency of the Terminal windows in Ubuntu with a command?
I already know about the profile method but want a command so that I can quickly swap between transparent and opaque.
My terminal is GNOME Terminal 2.30.2
You can use gconftool with the key /apps/gnome-terminal/profiles/Default/background_type (you might have to use a different profile name than "Default"):
This was tested in version 3.0.1, but the command should be the same.
