XFCE Power Manager settings seem to be ignored

[Shady]

ok i think i fixed it, under Session and Startup and on the Application Autostart, i had Screensaver and Screen Locker unchecked like this:





but I turn those back on and now it seems my display doesn't turn off after 10 minutes.

Lets keep this simple. All you need to do is this:

I can not open Lock Locker Settings, that is the first time ever seeing those settings for me.  I go to Setting and then click on Light Locker settings, it opens up for like 1 sec but it closes right away before i can look at it?
