Warning:
xscreensaver-demo: 17:52:13 is running as user "root" on host "localhost.localdomain".
But the xscreensaver managing display ":0.0" is running as user "nobody" on host "localhost.localdomain".
Since they are different users, they won't be reading/writing the same ~/.xscreensaver file, so xscreensaver-demo: 17:52:13 isn't going to work right.
You should either re-run xscreensaver-demo: 17:52:13 as "nobody", or re-run xscreensaver as "root".
Restart the xscreensaver daemon now?
