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.

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.

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 ...

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 ...

Settings -> Expose and Spaces -> Expose -> Acive Screen Corners -> Pick one of the corners and choose Start Screen Saver.

Assuming it also works for Lion (which I can't test), I uploaded this for you, you can download the screen saver file here. If you want to do it manually, do it like this: Open Quartz Composer.app. This is no longer ships with Xcode by default. You need to install Xcode first and then download the Graphics Tools for Xcode. Be sure to download the ...

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.

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 ...

Simple is best for me. Place this flat black image in a folder and set that folder as your screensaver source for the Classic screensaver style.

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:

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.

1. Screen Launcher Screen Launcher lets you choose any program to run as a screensaver. You could start a Powerpoint, a movie or any EXE or associated file. To install, simply unzip, right-click and click Install on the context menu. You can then use Screen Launcher just like any other screensaver.

It's an option in the Security preferences:

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). ...

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 ...

If you wish to lock your computer via a shortcut, then setup a shortcut like this. Filename: Lock Screen.lnk Target: C:\Windows\System32\rundll32.exe user32.dll, LockWorkStation Icon path: %SystemRoot%\System32\shell32.dll Icon Index: 47 You can even assign a shortcut key to the shortcut if you want.

Sometime before there was an article on howtogeek.com: Create Icons to Start the Screensaver on Windows 7 or Vista: Right-click on the desktop and choose New \ Shortcut from the menu In order to launch the screensaver, you’ll need to enter the full path to the screensaver file, followed by “/s” %systemroot%\system32\Bubbles.scr /s You ...

If I understand you correctly, that program should do what you want – at least start a normal application: AppStartSaver This is a simple screen saver for Mac OS X version 1.3+ that launches a regular Mac application, or a Unix executable, of your choice when the screen saver starts.

If you want to go for power efficiency, I would recommend to, like you stated, use power management to turn the screen off when it's not used for a while. If you don't care about efficiency and you like the effects screensavers can give, you can still use it.

I've run into the same problem. Good news: there's a workaround. I, too, thought it was tied to having network users. But it's not.. at least not directly. The problem is that if there aren't two or more local users, it hides the "Switch User" button (because apparently it thinks there's no other user you could possibly switch to). So the workaround is ...

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 ...

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 ...

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. In a default install it is set to Lock screen, and this overrides ANY timeout and password lock settings you have ...

You can run the screensaver with the /p switch, see here for more details.
