Hello everyone. I've been running LinuxMint Elyssa for a couple months now, no problems for the most part. The screen saver used to work just great. But now, when the computer goes idle, the screen fades to black, then immediately turns back on. The screensaver never starts. I tried several different screen savers. Changing the idle timeout doesn't help. I even unplugged my keyboard & mouse to make sure they weren't somehow indicating false activity.
Anyone know what the cause of this might be? Everything else video-related works just fine, dual monitors and all. Thanks.
