Can anyone tell me the difference between calling echo mem > /sys/power/state and pm-suspend?
pm-suspend often does not suspend my machine, whereas **echo mem > /sys/power/state **usually always works.
I think **echo mem > /sys/power/state **just skips the execution of some scripts or is there more difference?
When suspending does not work, I usually see this message in /var/log/pm-suspend.log
NETWM: Warning readIcon() needs buffer adjustment!
When I google this message it seems to be KDE related.
So, anyone a clue about this warning message and the difference of the above commands?
By the way, powermanagemt also effects desktop systems and servers, I don´t think it should be only in the laptop forum.
