In centos 7, click on your username in the upper right corner. Then click 'Power' and change the time to what you want. There is an option for 'Never' so that your screen will quit going black.

So through JAMF, a very wise man showed me a very simple thing I needed to add to the end of my script: killall cfprefsd Solved the problem entirely. While if you go into System Preferences, it still shows the old screensaver being selected, it works.

It's fixed by going control panel -> user accounts -> reset security policies.

If you go into System Preferences > Sharing and change the computer name to something other than the default, I would guess that name would be used by the screensaver, instead of your current string, and not keep getting re-assigned.

This is a glitch I've experienced caused by your mac reconnecting to your local network and thinking another computer of the same name is already connected. I'm not sure why it does that, but your computer adds a number to change it's name and avoid what it thinks is two computers with the same name on the network. You can reset the name by going to System ...

Thanks to W1N9Zr0 for pointing me in the right direction! In my case, it was an XP Pro (SP3) machine so the "energy" switch was not available, However, the "devicequery" switch indicated that it was either the mouse or the keyboard. Once I switched from the PS/2 keyboard I was using to a USB keyboard, the screensaver (and other power options) kicked in ...

This option never returns; ...

From a screen saving point, not as much as in the old times. However, you may want to consider saving your electricity bill - or the planet - and set a blank (i.e. black) screensaver on all your PCs.

Even if a wiki article claims that it happens, I would not put my trust in it. LCDs use a completely different technology than plasma or CRTs, which are susceptible to burn-in. An LCD pixel is a transistor that modifies the amount of light passing through it, and whether it is in the same state or not for long periods of time should not affect it. What ...

Yes, it does. Screenburn still occurs on LCD displays. I know this by experience. My phone, for instance, had its screen on for about 10 days and got minor screenburn; I could see the old image behind the current one. I've also used monitors that get temporary screenburn if left at the same image for more than an hour. Keep your screensaver.

This is a problem with this screensaver. Aparently the faster your computer is, the faster these bubbles will move. I compared the bubbles from a windows 7 in a VM and the native one on my desktop, and the speed changes are dramatically. In the VM it is slightly slower than I expect, but on my Windows 7 host, its pretty fast. Not dizzling fast, but ...
