If Windows Media Player is still installed, you can play a video on loop and minimize it (the sample "Wildlife" videos work fine for this). By default, as long as a video is playing, the screen won't lock.

Windows + L locks the screen immediately. Other than that, you'll need a utility to remap some other keystroke to that action.

It used to, when screens used to suffer from burn-in. Nowadays they're mainly used for fun, and to lock the computer when you're away from it. The Apple TV includes a screen saver (photos from the photo album) and periodic changes to the music playing interface to prevent burn-in of plasma TVs.

setterm from @whitequark's answer is a reasonable userspace tool, but it's not the whole story. The default console blanking behavior is baked into the kernel at compile time. It is configurable at boot time with the paramater consoleblank=, or in userspace with setterm. From the kernel documentation (kernel-parameters.txt): consoleblank= [KNL] The ...

You can set the desired settings in GSettings directly. Timeout for blanking the screen (seconds; 0 = never): gsettings set org.gnome.desktop.session idle-delay 3600 Timeout for locking the screen after blanking (seconds; 0 = instant): gsettings set org.gnome.desktop.screensaver lock-delay 0

Burn in There is a myth out there that LCD displays do not suffer from burn in. This myth is false. I have personally witnessed LCD displays suffer from burn in on multiple occasions. The big one that comes to mind was a client of ours with a display that need to be visible 24 hours a day. This is a trucking company that needs the display to be visible ...

Use display sleep to save your screen; use the screen saver as a lock. Let’s say you want to prevent burn-in after 3 minutes and lock the computer after 30 minutes. Go to System Preferences > Energy Saver and set the display sleep time to 3 minutes. Go to System Preferences > Desktop & Screen Saver and pick a lightweight screen saver (like Flurry). ...

Settings -> Expose and Spaces -> Expose -> Acive Screen Corners -> Pick one of the corners and choose Start Screen Saver. I chose top left and set a password for my mac so whenever someone is around and I need to step away I simply slide my mouse to the top left and bam..screensaver innocently starts hehe :D

If you don't want to use Expose, there's another option: The screensaver is actually an application located at: /System/Library/Frameworks/ScreenSaver.framework/Versions/A/Resources/ScreenSaverEngine.app You can just make an alias/shortcut to this app, drag the shortcut into your dock or wherever you want it and when you want the screensaver you can ...

I use a script I title idle.vbs: Dim objResult Set objShell = WScript.CreateObject("WScript.Shell") i = 0 Do While i = 0 objResult = objShell.sendkeys("{NUMLOCK}{NUMLOCK}") Wscript.Sleep (6000) Loop Every six seconds, this quickly toggles numlock on the keyboard, causing Windows to believe that someone is interacting with the keyboard, ...

Yes, it used to be a feature to prevent images being "burnt" into CRT screens: Before the advent of LCD screens, most computer screens were based on cathode ray tubes (CRTs). When the same image is displayed on a CRT screen for long periods of time, the properties of the exposed areas of phosphor coating on the inside of the screen gradually and ...

A screensaver does not save power. In some cases, the screensaver can cause the computer to use MORE power (complex 3D screensavers). Powering off modern monitors will not cause any detrimental harm to them. If you want to save power, it is best to turn them off completely when you are not using them.

Actually, Windows screensavers did have this feature (at least those included as part of the Plus! pack, which old-timers should remember): Indeed, a really useful bug made the hot corners specified for Plus! screensavers a global setting that applied to non-Plus! screensavers as well! The easiest way to get similar functionality in Windows now might be ...

You can use the xset command to disable screen blanking and locking. E.g. xset s off (turns off the screen saver) xset s noblank (turns off blanking) You can also use it to disable the power management using dpms to power the monitor down xset -dpms I use these commands in a script set to run at login to stop the screen blanking on my MythTV machine. ...

Try setterm -blank $minutes (or pass 0 to disable); -powersave option may also be related. setterm has a plenty of other useful options, too. If you want to set these attributes on system startup, consider writing an initscript. This is just a script placed in /etc/init.d directory. Let it be called setterm: #!/bin/sh [ "$1" == "start" ] || exit 0 # only ...

If you enable "Show fast user switching menu" in System Preferences → Accounts, then the lock screen gains a new button "Switch User..." which will take you to the login screen. On Mac OS X Snow Leopard and previous, the Switch User button appears on the password dialog: On Mac OS X Lion, the button appears at the bottom of the screen:

powercfg is built into windows and lets you control and view lots of power management settings. powercfg -energy -trace This will create a very detailed power management event log, energy-trace.etl. Open it with Event Viewer and filter log by Event Source: Kernel-Power, Include event ID: 62. This should give you events that look like: The application ...

The simple answer (as you alluded) is to have your screen saver turn the monitor off instead. This of course provides the least chance of burn-in and also saves a bit of power.

I'm not 100% sure if these steps will work if someone isn't logged on though! To enable the screensaver, first choose the screensaver you want. Look in C:\WINDOWS\SYSTEM32 for files with the .SCR extension - typically there are the following (at least on my Enterprise Installation)... SSTEXT3D - 3D Text BUBBLES.SCR - Bubbles ...

I find the screensaver useful for privacy: They conceal the programs/documents left open on the screen Most can be configured to lock the computer, requiring a password to gain access to the session.

Open Configure Desktop/Personal Settings. Go to Advanced > Power Management > Edit Profiles, and in the setting for the profile you are using (or all profiles) change the option for When the system is idle for more than XX min to Do nothing.
