Faster photo viewer

Not sure why they use Gnome Image Viewer as the default image viewer in Ubuntu. I prefer gThumb, which is a lot faster.

Simply open up All Settings -> Details -> Default Applications and select your favorite image viewer there.

Automatic mute when unplugged

• Install pavucontrol 
• Open PulseAudio Volume Control
• Go to Output Devices
• Choose Speakers under Port
• Click the mute button

 Now notice how your computer automatically mutes if you unplug your headphones!

Sticky Edges

Seems that sticky edges cannot be configured under Display settings in 12.10.
Instead go to CCSM -> Unity -> Experimental and uncheck Capture Mouse.

Move window

Working with two monitors is very nice, and there is a nice feature in Compiz to quickly move current window to the other display.

To enable it:

1. Install packages compiz-plugins compiz-config-settings-manager
2. Open ccsm and enable plugin Put
3. Go to the configuration for Put
4. Set a keyboard shortcut for the function Put to next output 
5. (Not always needed) Restart Unity by running setsid unity from a terminal
