I installed BOINC yesterday and can see in BOINC manager that the projects are running. I read the existing instructions on setting up the screensaver and all I get is a blank screen.

This is the procedure I followed:


    1. Control Panel > Scrensaver Settings > Choose "BOINC" screensaver
    2. BOINC Screensaver Configuration
    * Blank screen after: "Never"
    * Run BOINC screensaver for: "1 hr"
    * Run project screensavers for: "1 hr"
    * Switch between project screensavers every: "5"



I always lock my screen (Win+L) and after 5 minutes the screensaver is supposed to trigger. Except... blank screen.

I followed the instructions as written, so I suspect either hardware or software compatibility. I listed my specs in case anything in the list is incompatible with the screensaver.

Is there any tweak I can make to my settings or will the screensaver simply not work on my system?



  • OS: Windows 10 Pro
  • Version: 10.0.16299 Build 16299
  • Processor: Intel Core i5-6600 CPU @ 3.30GHz, 3301 MHz, 4 cores, 4 logical processors

Which projects do you run, and is this on the CPU or GPU or both?

I am running only SETI@home and Rosetta@home.

As for whether it is on CPU, GPU, or both, I do not know how to determine that for sure. I looked in the event log and saw two separate lines that make me suspect both are used: "Requesting new tasks for CPU" and "Requesting new tasks for AMD/ATI GPU".

I looked under computing preferences and saw nothing to dictate whether to use CPU or GPU exclusively. When I installed BOINC, I used the default settings and didn't configure anything.

I tested this with both BOINC and Windows built-in screensavers and at least on Anniversary Update lock screen simply doesn't show screensavers.

Screensavers work fine if you just leave the computer idle without switching to lock screen yourself.

I was able to replicate that. However, I need to manually lock my computer every time I step away because of others with no impulse control. They will gladly use my profile if I step away for even a second and the screensaver hasn't kicked in yet.

In other words, having the BOINC screensaver activate when the screen is manually locked would be a good feature to have.

Some more googling and it's actually the lock screen that by default blanks screen after 1 minute. You can change that by following the steps in this article.

The plot thickens. I now see Rosetta screensaver, but when it's time to switch to SETI screensaver, I get blank screen.

I checked the settings and it appears that SETI uses my GPU, whereas Rosetta uses the CPU.

If SETI uses the GPU, does that mean the screensaver won't work? Would I have to force CPU to be used instead? Actually, I don't know how to do that. I've Googled it, but I haven't found anything obvious yet.

Oh, for the days of Windows 95, when the SETI Screensaver worked out of the box...

Seti's screen saver/graphics only work on CPU tasks. Their GPU science applications don't come with a graphics application.

Doubt GPU jobs have a screensaver part. Open BOINC Manager, select Tasks view, select the running GPU task. Button to left to show graphics will likely be gray.

It looks like you're right. Graphics is greyed out. Is there a way to request CPU jobs only, or is SETI GPU only nowadays?
