A simple little app today, Brightside. What this does is to allow you to traverse your desktops in Ubuntu Edgy by mouse, so that you can use the mouse to scroll from one virtual desktop to the next. A colleague introduced me to this years ago on a Linux install, and I couldn’t find it on any others since, until today. I’m now back to the setup I had then, where I have 4 desktops in a square shape, and move around them by mouse. It also allows you to define custom actions for moving the mouse into corners of the screen, so now if I move the mouse to the top left the screensaver starts, if I move it to bottom left it mutes what is playing. Very nice features. Simple install:
sudo apt-get install brightside
Once it is installed, go to System > Preferences > Screen Actions to set up as you wish.
