Trying something different. I *enabled* the screensaver and set it to a large delay. I also disabled power management, with Hiber and Suspend, there. This is to jog the settings. We shall see.
@paul1149,
Also consider:
1) The Monitor tab under your Power Manager AC settings.
2) Look at your Light Locker Settings (Menu->Settings->Light Locker Settings).
Hi torreydale,
Yes, on the monitor tab I had turned the sliders all the way to "Never" Land.
Light Locker is interesting. Hadn't opened it before. So far this morning I haven't had any lockups since enabling screensaver. I'm going to leave it as-is for a while for testing. Then I'll return to this and see how it affects things.
Thanks!
Thanks torreydale, I've been at work all day
@paul1149,
Good idea. Some of these settings might be working against one another. And I'm not surprised you overlooked the Light Locker Settings. The name isn't intuitive and I just learned about it 1-2 months ago myself.
@Jerry,
No problem. Reaching out indirectly helps me, too.
Those changes I made have solved the problem. Now to find which one did the trick. But that's not crucial. Thanks everyone.
The problem returned this morning, and when I went to check the screensaver settings, once again its daemon wasn't running. I think that is the problem, and IIRC I had removed it from autostart when I was parsing some settings, thinking I didn't want a screensaver. I've turned it back on autostart, so we shall see.
