Lubuntu users wanting more control over their desktop will soon have their prayers answered, in the form of “Lubuntu Tweaks”.
Lubuntu Tweaks is a configuration tool for the lightweight LXDE based Ubuntu flavour, there are only a couple of things you can do with the app right now but the functionality of it should grow immensely with Lubuntu planning on switching to the Qt-based LXDE version.
If you want to install it and check it out (remember, very limited functionality right now) then just use these commands :
$ sudo apt-get-repository ppa:lub
$sudo apt-get update & apt-get install lubuntu-tweaks
Once installed you can open it from your Lubuntu Menu.
