After installation of El Capitan, all seemed OK, but noticed later on that my screen saver no longer started up after the designated delay period - checked settings and all were good (the same as before the upgrade). Now the screen saver will only start by forcing it to launch with a hot corner - anyone else noticing this behavior?
iMac, Mac OS X (10.1.x)
Launch the built-in Activity Monitor application and select the Energy tab. Select
View ▹ All Processes
from the menu bar, if it's not already selected. Also select
View ▹ Columns ▹ Power Assertion
Click the heading of the Preventing Sleep column to sort the process table. Which processes, if any, show Yes in that column?

Thank you, Linc - this was it - you nailed it! Found a third-party app I use and it had somehow launched a "helper" sub-app that was preventing sleep - so nothing wrong with the screen saver functionality for an OS standpoint - Screen saver is now launching at the designated intervals - thanks again!
After Upgrade to El Capitan, screen saver will not start automatically - can only start using Hot Corner?
