Sometimes just changing the time on the screensaver (not the type) to something else, say from 10 min down to 1 and then back to what you had it before will allow the screen saver to function normally.
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 per the settings.
I find the culprit is typically a media player. You'd think it'd only be when playing video, but I have had some music players hold off the screen saver. For example I had Amazon Music and Groove open and paused today, and just found my screen still unlocked after an hour.
I don't know of any program that does this, but the way to find out is via the GetThreadExecutionState() function which will hold the value ES_DISPLAY_REQUIRED if the thread is currently blocking the screensaver from being activated.
I was thinking about using a domain power plan to actually turn off the screens after idle time, but I think it would take too long for the screens to wake up when someone comes back to their PC or laptop. Requiring the user to type their password every time the PC is idle for 1 minute will not fly, but I can get away with it locking after 10 or 15 minutes of idle time.
The settings work if applied, but I want to have a screensaver come on after 1 minute of idle time, then have the PC lock after 10 minutes of idle time. If the policy to require a password on screensaver is enabled the user has to enter their password each time, which will not work in my environment.
At 1 minute the screen will go blank, but the user will be able to move the mouse to wake it back up without a password. After 10 minutes the screensaver will turn on (with the same blank screen) and lock the PC.
Ofc there are other solutions, but this has proven to be the quickest and the easiest one which works on all windows OS versions and overrides settings from other applications (whichare disabling screensaver).
Windows is an operating system for personal computers (PC), created by Microsoft. Most screensavers will run on any modern version of Windows, from XP and Vista up to Windows 7, 8, 10 and 11.
At the time, he was on the Windows OpenGL team. They had successfully implemented the API with hardware acceleration, but had nothing to show it off. Windows NT 3.5 was very close to shipping with OpenGL support, but there was nothing in the product that let the user know that this feature even existed. He had to find a way to advertise the feature without risking product stability.
When NT 3.5 launched I was working for a small client/server development house. The company was an early Microsoft Solution Provider in the UK and were transitioning from LanMan/Sybase to NT/MSSQL. My role was largely running the in house IT but I was often farmed out to install infrastructure and fault find network problems on client sites.
A question, with Win 3.x (also the Win 9x line?) I remember screensavers having a max. allowed size of 64kB. The 3d Pipes screensaver I downloaded (hopefully not from a shady site) comes with 610.304 bytes.
When was that size limit lifted? With the NT line?
Some months ago I published my solution to this problem here.As a reaction on the post of tfrederick74656 (below) I stated to have a better solution using the Item-level targeting for the Remote desktop.
After I posted this, it worked for one or two days and then did nothing anymore.After some months of doing other things and wondering what really happens I started all over again.And this time I really have the solution to the problem!
I know this is an old question, and this is a bit hackish of an answer, but you could simply make a Group Policy Preferences Registry item to disable the screensaver when the session name contains RDP. You could set up the registry item to set the timeout to something ridiculous like 9999 minutes:
Then set up the targeting to only apply when the session name matches an RDP session. There's no wildcard, but the number is incremented at each RDP logon, resetting at reboots, so just put in a bunch.
GPO that targets just the specific OU with the Terminal Servers -note* we are targeting computer objects. Use loopback policy to enforce the screensaver settings on users; if configured correctly, it should apply to all users at logon.

No, we haven't heard of this yet.
But let's eliminate a thing or two before I forward this to development.
1. Do you know what kind of videocard you have?
2. Do you know which drivers it's got installed?
2a. Are those installed by Windows 10 or by you from the GPU manufacturer's website?
I ask this as it's the first thing the developers will ask: do you have OpenGL support installed in the drivers? I am looking on the Internet and it would seem that Windows 10 comes with no OpenGL support (??)
The drivers and such are OK. It's just the screensaver not loading. When in screen options and select scrensaver you can prestest it. Then it loads and runs fine. So all drivers and things are good.
I.m gonna investigate further :-)
Yes, but the thread you eventually link to is about one of the later beta versions (February 2015) where it doesn't work. So I am just wondering if all OpenGL is still working in the release version, also because Windows Update will pull in all kinds of newer (WHQL) drivers that not necessarily contain things like OpenGL and OpenCL because these are still direct competitors to DirectX and DirectCompute.
May sound daft, but win 10 has two settings in Personalization; Lock Screen.
One is screen timeout settings and the other Screen saver settings.
I had set the screen to turn off and set the screen saver to BOINC and whilst the preview worked it never started.
I then changed the Screen timeout to never and it seems to work.

I have the same problem... i'm running the same BOINC version. Ever since the day i started it in Windows 10, i noticed that i get no preview, or screensaver. I don't really care too much since i did notice that my points per day tripled with the Windows 10 update, but i do leave my monitors on once every so often, and the protection would be nice. I'm running 2 GeForce 760's in SLI with drivers from NVIDIA GeForce experience constantly updating them. Also running 5 SIIG USB 3.0 dual monitor adapters to handle the 6 monitors i have. i don't get screensavers on any of the screens.
Hi there, guess what? Since upgrading to Windows 10 BOINC screen saver will not run too. Ran fine on 8.1. It appears it's trying to start once every second, however when I look under 'tasks' in BOINC Mgr it show all is running fine. Sounds like lots of people are having the issue. Any ideas? Thank you ...

Can people please post what make and model videocard/GPU they have, and what drivers they have loaded for it? Did Windows Update install those drivers, or did you manually get them from the GPU manufacturer's website?
Windows 10 automatically installs 'the latest updates', in the Home version of WinX you can't even opt-out of this. It's possible that the WinX version of the drivers miss out on OpenGL, a required component to run the screen saver.
One easy to use and install application is GPU Caps Viewer which shows whether things like OpenGL, CUDA and OpenCL components are installed and usable. Can you please tell about that?
Also, if you have a non-keyboard non-mouse USB device attached, try to detach that. If your screen saver starts working after that, it's Windows reading the slight oscillations that this device makes while it's not in use. Example given, a racing wheel or joy-/flight stick can show this behaviour.
I managed to get the screensaver run, but I don't know exactly how. At first it did NOT run.
I went to Windows personalize... lock screen... screen saver settings. I chose "BOINC". I didn't change anything under the "Settings..." tab. Preview run OK. I set "Wait" to 1 minutes and apply + OK. Then exit everything and waited. No open programs, no movement, only Boinc client running in the background. Screensaver never run.
Then I located Boinc program directory and boincsvr.exe. I tried all the compatibility modes for that file (file properties... compatibility... "Disable display scaling...", "Run this program as admimistrator" and one at a time all the different Windows versions). That didn't make it work.
Then I went back to Windows personalize... lock screen... screen saver settings. I see there was also a screensaver called "PBOINC". It had been there already at the first time. Now I chose that "PBOINC" and tried the preview. Screensaver only flashed on the screen, but I think that happened because maybe I accidentally moved the mouse a little bit.
Now comes the strange part. There was no more screensaver called "PBOINC". It had disappeared from the list after that short preview. The regular "BOINC" had been automatically chosen again.
Well, then I tried preview for that regular "BOINC" again and it worked. I went back to desktop and waited.... and now the screensaver RUN after 1 minute !
Then I started to remove the compatibility modes for the boincsvr.exe. In the end, I had removed them all and screensaver was still able to run after 1 minute.
Ps. I had set the "Screen timeout setting" to "Never" already long time ago. I didn't touch that setting.
