Tweak the screen saver and power saving options – By default, the Ubuntu desktop is configured to activate the screen saver and lock the screen after five minutes of inactivity, then put the display to sleep after thirty minutes. For home use, especially if you are the only person at home, this is not necessarily the best setting. To modify the default configuration, access the “Screensaver” utility from System > Preferences > Screensaver.
The only two changes I like to make here are: Change the screensaver theme from “Blank screen” to “Random,” then uncheck “Lock screen when screensaver is active.” Note that if you use your computer in a public place, or you live with people you do not trust, it’s best to leave these settings unchanged. As a matter of fact, if you are in a public place and you need to step away from your computer for even a few seconds, activate the screensaver manually. If you want to modify the display’s power saving setting, click on the “Power Management” button.
Modifying the Screensaver preferences
Clicking on the “Power Management” button brings up this window. You can also access it separately from System > Preferences > Power Management. By default, the display will “sleep” after thirty minutes of idleness. You can change to the other times options or to never. Your choice.
Modify window behaviors – When you double-click on the title bar of any window, the default behavior is to maximize it. Since their is a maximize button you can use for this, I always like to shade or roll up a window when I double-click on its title bar. To change this setting, launch the “Windows” utility from System > Preferences > Windows. Under “Titlebar,” click on the drop down menu and select “Roll up.” Close the window. Now when you double-click on the title bar of a window, it will be shaded or rolled up. It’s much cooler than the default behavior.
Power Management settings
Modify startup behaviors – I like to have my computer remember the applications that were open before I rebooted, shut it down, or logged out (this is not the same as startup applications). To make this happen, launch the “Startup Applications” utility from System > Preferences > Startup Applications, and click on the “Options” tab. The only option here is to check or enable “Automatically remember running applications when logging out.”
Install and enable Gufw – Gufw is the graphical interface to ufw, Ubuntu’s friendlier-than-IPTables firewall utility. How to install and configure Gufw has already been covered here.
