Mint -Suspending When Set Not To Suspend, or Not Restoring

[johnywhy]

hi

on 17.2 xfce

it appears that my mint is suspending when plugged in, or not restoring from suspend, or not powering down on battery.

i left the machine idle for about 6 hours. When i returned, all the power-up lights were still on. So i don't think it was suspended or powered down, just display off.

Moving the mouse and touching the keyboard did not bring up any display-- the screen stayed black. I could hear disk activity.

i waited about a minute, and that was too long to wait. I had to force power-down with the hard button.

Maybe it was not suspended, maybe the display was off and failed to turn back on.

My power cable is funky, so not sure whether it was plugged in or not. But either way, t it did not seem to behave as configured or expected. I had similar experience in Rebecca, and turned off all power management for that reason. Seems 17.2 power management is still problematic. Might be a problem with my hardware.

Is there a system log i can share to help find out what happened?

xset manages a screen saver, standby and suspend. These functions run in parallel with others that may be loaded. To determine current settings, in a terminal run:
xset q
To turn off the xset functions, in a terminal run:
xset s off
xset -dpms
These changes do not hold thru a re-boot but can entered in a script file, or directly in a 'startup applications' launcher.

Will try when back at my machine.

Is this different than the xfce power manager? Those settings seem to persist through reboots, tho they don't seem to be working right.

Thx

xset is part of x11-xserver-utils. I don't know for sure if they are installed with xfce, I use Mate, but your problem sure sounds like an xset issue.

here's what i'm seeing:

DPMS (Energy Star):

  DPMS is Disabled

Rather than write a boot script to make my desired settings persist, i'd like to determine if the xfce power manager is malfunctioning (which it seems like it is), and do a bug report to mint if so.

Currently, when plugged in, the computer is totally powering down after a certain amount of time. Do the xset settings indicate that? The xfce power manager does not seem to reflect that behavior.

[Mik3e]

The screen saver is set to 0 and DPMS is disabled so xset is not the problem.
