Jerry3904, thanks for the reply. Yes, that's just the man page. I'll post my questions on the xfce forum.
EDIT so as not to bump [corrected]
I'll just sum up in case it's useful to others with the problem of screen blanking during video playback
El malo de la película
has been xscreensaver all along. xfce4-power-manager presentation mode or "xset s off -dpms" disables blanking as set in power manager, but not xscreensaver. To prevent blanking, xscreensaver must be disabled through the gui (Settings/Screen Saver/Mode) or command line. (xdg-screensaver is also thereby disabled.)
I still wonder why we have so many screen savers; at least I have a simpler solution
Code: Select all
xset s off -dpms
An alternative is caffeine from the repo.
Presentation mode in xfce4-power-manager-1.6.1
disables dpms and
xscreensaver, i.e. it now works as intended :)
Thanks to ToZ on xfce forum for this.
