Fancontrol ignores pwmconfig settings after suspend to ram/disk

[emil]

When I suspend to ram/disk and reboot my pc, fancontrol doesn't use the config file in /etc/fancontrol.
Killing and restarting fancontrol solves the problem.

I am using a Asrock A780GM-LE amd motherboard.

Status changed to 'Confirmed' because the bug affects multiple users.

Same bug here with Ubuntu 12.04 on gigabyte P965-DS3.

In my case fancontrol does not control the fan anymore after waking up from suspend to disk. Doing a manual restart of fancontrol fixes the problem. When waking up from suspend to RAM the problem does not occur.

Thank you Erik for the workaround.

[Gert Brinkmann (g111)]

Thanks, Erik. The script does work for me. (btw. I made it executable like all the other scripts in this directory. I do not know if it is necessary, but I think so.)

So IMHO this script should be included in the fancontrol package as long as not other solution exists.

still broken in 13.04. work around still fixes issue.

The same problem at HP proBook 4515s. It worked in 12.10...

If your system uses systemd you can edit /lib/systemd/system/fancontrol.service and add under [Service], Restart=always

It's a better workaround than using pm-utils

For example

[Unit]
Description=fan speed regulator
# Run pwmconfig to create this file.
ConditionPathExists=/etc/fancontrol
After=lm-sensors.service
Documentation=man:fancontrol(8) man:pwmconfig(8)

[Service]
ExecStartPre=/usr/sbin/fancontrol --check
ExecStart=/usr/sbin/fancontrol
PIDFile=/var/run/fancontrol.pid
Restart=always

[Install]
