External sources can un-DPMS the monitor

[haarp]

Hello,

there are ways to un-DPMS a monitor while not interrupting the screen locker, e.g. power managers that react to "inhibit screensaver" events. xsecurelock with XSECURELOCK_BLANK_DPMS_STATE in use does not handle this situation well. The display(s) will activate and stay active (albeit blanked) indefinitely, unless acted upon by the user.

This consumes power unnecessarily. It would be cool if xsecurelock could put the display back to sleep when this happens. I don't know if detection of the current DPMS state of all monitors is possible. Maybe just repeating the DPMS command repeatedly while the monitors should be sleeping would do the job.

Thanks!

The usually intended way to do this would be to configure DPMS with xset in addition to xsecurelock's own blanking.
