fan noise after resuming from suspend

[Xiang Liu]

hello everyone,

I have found that the terrible noise of my cpu fan. It works well until after suspending. (sleep by xfce-power-manager or press the sleep button)

I examined and compared the values of /sys/devices/virtual/thermal/cooling_device{3,4,5,6,7}/cur_state, and found their values are changed after resuming from suspend.

so I wrote a simple script and hoped it to be run after each suspend.

=========








for i in /sys/devices/virtual/thermal/cooling_device{3,4,5,6,7}/cur_state; do echo $i ; echo 0> $i; done=========

But I wonder how can i trigger it after resuming in xfce environment.
thanks.

Xfce has no special facilities for that, however you should be
able to execute your script by creating a pm-utils hook, see

You can also achieve something similar by dropping in a script in

/usr/lib/systemd/system-sleep/

See systemd-suspend.service(8) for details.

thanks, In fact, the full story is that I have tested the pm-utils hook before I asked help here.
It works only if pm-suspend was used to suspend the system.

but the /usr/lib/systemd/system-sleep way works.
