Ubuntu Tweak is an application to config Ubuntu easier for everyone. It provides many useful desktop and system options that the default desktop environment doesn’t provide.

As a Ubuntu user, you always get excited when you see something new in Ubuntu world. You play with new applications, new themes, new applets… After playing with them, you may find something break the desktop, and you don’t know how to recover to the original style.

That’s what the Desktop Recovery will help you.

Desktop Recovery is the tool integrated into Ubuntu Tweak to help people safely tweak with desktop settings, and never worry about how to go back.

It has three basic actions:

• Backup: backup the current settings, keep as many as backups you want;
• Recover: recover to the backup;
• Reset: even you don’t have any backup, you can also reset to the default settings;

And what items does Desktop Recovery can backup? Here’s it is:

• GNOME Desktop settings: Panel, Themes, Background;
• Application settings which use GConf: gedit, Compiz, Empathy, Nautilus… You know, almost every desktop applications;
• System components: Input method (ibus), network-manager, proxy…

You can see, Desktop Recovery covers almost everything of desktop/applications.

One thing You MUST know: it will only operate with the setting, not the files related with the setting. E.G. It will backup the setting about the background name, but not the real background file.
