Yes it does help Scott, I was not aware of the xset utility, thank you.
xset -q returns this data about things related to this:
Screen Saver:
prefer blanking: yes allow exposures: yes
timeout: 0 cycle: 600
DPMS (Energy Star):
Standby: 1200 Suspend: 1800 Off: 2400
DPMS is Disabled
I assume those numbers are in seconds, and that, if so, is NOT what the
menu's for that are showing. Now the 64k$ question is what has disabled
it, given that the Xorg.0.log says it is enabled? No man page, --help says
a +dpms turns it on, and a subsequent query says:
DPMS (Energy Star):
Standby: 1200 Suspend: 1800 Off: 2400
DPMS is Enabled
Monitor is On
Now, in the -force menu's it outputs for error's, indicates a timeout=0
disables dpms, but from the same query:
Screen Saver:
prefer blanking: yes allow exposures: yes
timeout: 0 cycle: 600
So timeout is still 0. ???
I have a new kernel ready, so I may as well reboot to it and see if this
survives a gracefull reboot from the kde leave menu.
I'll report success/fail before the evening is completely fini.
Thanks again.
