Hi
The boinc screensaver will not start in windows 10. I can see boinc is running , but screensaver is not. Any solution or knowledge to this problem ?

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 :-)

i'm running Boinc 7.4.42 x64 , with wcg as project

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.

Sorry... also I'm running World Community Grid and GPU Grid. But that never had problems before. Maybe Microsoft or NVIDIA will come out with updates soon.

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.

My setup:
W10 build 10525, Boinc 7.6.8 x64, Nvidia GTX 960 + driver 355.80, this host is only crunching for Einstein@Home at the moment

For what it's worth... Here's an important update.

Microsoft released a new Windows 10 Insider build today, Build 10532, and it appears to fix the "activity detection" problem I was having with my USB Logitech G27 Racing Wheel. My testing confirms that, for the purposes of detecting activity to disengage the Screen Saver or to turn the display back on, Windows correctly no-longer detects activity (phantom or real) from my wheel and pedals. This also fixes the BOINC problem, where the "In Use" settings would think that my system was always in use because of the phantom inputs.

I believe the fix will be sent, at some point, to regular Windows users, sometime on or before the "Threshold Wave 2" release scheduled for sometime in October 2015.

Kind Regards,
Jacob
