OK, after some more "rooting around" @ the Ubuntu site (https://wiki.ubuntu.com/Bugs/FindRightPackage#Finding_the_Package_Name), I (finally) found the page with the information pertaining to my problem: https://wiki.ubuntu.com/DebuggingScreenLocking/HowScreenLockingWorks. I sincerely apologize for the "wasted bandwidth"....

When I activate Screen Lock and leave it alone, I have to reboot my system to make it active (i.e., the system "goes to sleep"). I didn't have this problem with v. 14.04. Otherwise, things seem to be OK... Processor: AMD Athlon(tm) 64 Processor 3500+ Memory: 4G Hard Drive: 250G Samsung SSD Additional info: if I have my machine sitting at a "normal" login (i.e., after reboot), I have no problems. It's only when I activate "screen lock" that I have to reboot my machine via hardware "reset" button or power cycle.
