Post Monitor not powersaving
This is another one those issues I have running 8.5: My computers running 8.5 (one ATI and one nVidia) can't seem to use monitor power saving.
I've been searching and I see lots of threads, for example:
http://mepislovers.org/forums/showthread.php?t=25656
http://mepislovers.org/forums/showthread.php?t=26104
http://mepislovers.org/forums/showthread.php?t=24168

So I've found several areas that address screen management:

  1. Alt-F2 >>> Power Management >>> General Settings >>> Let PowerDevil manage screen powersaving
  2. Alt-F2 >>> Power Management >>> Edit Profiles >>> Performance profile (since it's a Desktop and ac is plugged in) >>> Screen >>> Enable display power management
  3. Alt-F2 >>> Power Control >>> Enable display power management

I've tested every combination of those to set a standby time and suspend time, but no luck.

I don't have a screensaver running.
And these monitors do go to standby fine running MEPIS 8.


Here is the output from this command:
Code:
xset q

Quote:
DPMS (Energy Star):
Standby: 1200 Suspend: 1800 Off: 0
DPMS is Enabled
Monitor is On


What's missing?
Thanks

I also have this problem since moving from 8 to 8.5. Like the OP I've tried the suggestions in the above threads, but something's overriding everything I try. I'm just going to stop typing now and then post how long it takes for the screen to go blank.

60 seconds.

xset -q gives (some irrelevant info deleted) gives

Screen Saver:
prefer blanking: yes allow exposures: yes
timeout: 0 cycle: 600
Colors:
default colormap: 0x20 BlackPixel: 0 WhitePixel: 16777215
DPMS (Energy Star):
Standby: 720 Suspend: 1800 Off: 3600
DPMS is Enabled
Monitor is On

If anyone's got any new ideas, I'd be very glad to hear them. I can't watch anything longer than a cat falling off a shelf.

i have an issue with 8.5 not being able to stop the console from being locked when the screen saver/power saver kicks in.

8.5 is different, and the desktop locking thing will likely drive me nuts, but i've found it to be snappier on my notebook than 8.0.

i'm in the process of by a larger drive that will be used for a fresh 8.5 install on my desktop.

What happens if you do a 'kdesu systemsettings' (WOQs) and then set things? (I'm away from mepis at the moment)

kdesu systemsettings:
Display > Power Control.
Enable display power management Disabled, StandyBy after disabled, Suspend After disabled.
Screensaver settings: Start automatically Disabled

OK going to apply it now and put a stopwatch on.

1 minute exactly, the display disappears. There must be something telling it to shut down after 60 seconds.

Is it possible that the monitor is timing out due to Energy Star settings? (independent of the OS)

Thanks - would disabling DPMS solve that do you think?

Ah... nearly there. As root, edit /etc/X11/xorg.conf and change three three places where DPMS occurs, in the Monitor sections, to "false". Display now dims after a minute or two but doesn't go off altogether, thank goodness. Just need to stop the dimming now.
