Screensaver is not working after Windows update to 1903.

After a lot of testing, I have found that my screensaver works as long as I do not have my VKB-Sim_Gladiator_MkII Joystick plugged into the usb port.  I did read that most of the time where this issue is happening, it's related to usb devices / ports and the power settings, or glitchy drivers.

That said, when I first built my new pc the joystick was plugged in and the screensaver worked just fine.  I still think it has something to do with usb devices, but the issue is with MS drivers that are part of the OS.  Maybe someday they will fix that and things can return to normal.  For now I just leave the joystick unplugged and everything is working good now for about 2 months.

I have not had the screensaver working problems for a couple of years with Windows 10. Just occasionally it would work for a day or so after an upgrade and then stop.

I unplugged all the USB devices - Logitech camera, MS joystick and CH Pro pedals (for flight sim). This did not work, however I was running nVidia GeForce Experience and selected IN-GAME OVERLAY OFF and the screensaver and power saving started working again reliably.

Since then I have had to start using Edge rather than IE 11 as MS Teams required it. When Edge is running it prevents the screensaver working. A full reboot will reset the system and it works again. This problem does not occur with IE 11. It seem Edge is preventing screensaver or power saving working.

Richard,

Thanks, I tried many other solutions and this one worked. It was my usb game controller attached to a hub that was causing the hangup.

Same here. Screensaver works fine; update to 1903 on 11 October 2019, screensaver fails to kick in. The only change was MS's update.  MS broke the screensaver.  QED.

I have same issue. The reply from Manjunath did not help.

This worked for me too.  Apparently since 1903 the screen saver only functions(for me) if the "On resume, Display Logon Screen" option is checked.  If I uncheck it, screen saver won't kick in.  It's getting really annoying having to enter my password/pin every time, but still better than no screen saver or sleep mode at all.
