Xfce Power Manager sets DPMS, so Xscreensaver should not be used with Xfce
Power Manager as such. https://bugzilla.xfce.org/show_bug.cgi?id=10205
If I e.g. set Mode to Presentation in Xfce Power Manager (that is equivalent to
setting 'xset -dpms', lock and unlock by 'xscreensaver-command -lock',
I think Jarno and Jamie are misunderstanding each other:
> Could the "Disable Screen Saver" mode be changed to not change DPMS
settings, when not locked?
I see no reason why selecting "Disable Screen Saver" should prevent
kicking in DPMS at all as Jamie stated in comment #18 this is more or
less
As for #16, is the XQueryExtension "DPMS" setting the one that can be
controlled by 'xset +dpms' and 'xset -dpms'? Using the latter makes DPMS
disabled, but as far as I switch to advanced tab (from another tab) in
xscreensaver preferences (or possibly do another action in xscreensaver)
the setting
> Ok well that shouldn't be. I don't know what's wrong.
This is what the ticket is all the years talking about :)
Comment #14 implied just a bit that this behavior could be intended if
the screensaver is disabled so I wrote comment #15 with the potential
possibilities how this could be handled.
The DPMS settings in xscreensaver-demo are not grayed out on my system,
DPMS is there enabled but it never kicks in. Why is it a "terrible idea"
if it would in this case?

Is this really the case? At least xscreensaver-demo does not gray out
the DPMS settings while it grays out the screensaver settings if the
screensaver is disabled. So technically this would be a bug
DPMS is disabled, if you have chosen mode "Disable Screen Saver" in
Xscreensaver's preferences. It would have to be changed to use DPMS
while being locked.

I got around this dpms-is-always-disabled nuisance
in Xubuntu 16.04 by calling a bash script
in ~/.config/autostart/.desktop. The script
sleeps for 10 seconds and *then* calls xset in such a way
as to enable dpms. The 10-second delay
is evidently long enough for the startup of the X session
I have installed xscreensaver into Ubuntu 14.04.
I had to replace gnome-screensaver{,-command} with xscreensaver to get it to
work.
But after that I find that DPMS is Disabled, and it annoys me.
Even without activating xserver, the xset power management is broken:
I could enable DPMS with this
This is what I get on my desktop system:
sworddragon@ubuntu:~$ cat .xscreensaver | grep dpms
dpmsEnabled:True
dpmsQuickOff: True
dpmsStandby:0:10:00
dpmsSuspend:2:00:00
dpmsOff:4:00:00
sworddragon@ubuntu:~$ xdpyinfo -queryExtensions | grep DPMS
DPMS (opcode: 147)
I have a quite similar problem here (12.04 LTS amd64). It seems
xscreensaver is somehow not controlling the dpms settings correctly.

I think the root of the problem is that if xscreensaver is built with
DPMS support, there doesn't seem to be any setting to make it just leave
DPMS alone. Also, we probably need the DPMS support because it allows
xscreensaver to conserve resources when DPMS turns off the monitor.
So as it stands
I am having similar issues on Xubuntu 12.10. Everything worked perfectly
on earlier versions of Xubuntu. Now, no matter what I do, xscreensaver
will not allow the monitor to power off. In fact, if I run
xflock4;;xset dpms force off the monitor powers off, and gets woken
back up5-10 seconds later!
