acerhdf: not enabled by default

[Neil Wilson]

The acerhdf module is in the karmic kernel, but requires a manual sysctl to enable it.

Can we activate it by default in the sysctl.conf?

Just so that anyone looking at this bug will be able to make acerhdf work, here's the workaround from the duplicate bug report:

"To make fan control and acerhdf work, I need to do a 'sudo -s' (regular sudo won't work) and then 'echo -n "enabled" > /sys /class/thermal/thermal_zone0/mode' (this command is recommended when doing "dmesg | grep acerhdf)".

However /sys/class/thermal/thermal_zone0/mode is reset to "disabled" after every reboot or shutdown. To make enebled permanent I had to add 'echo -n "enabled" > /sys /class/thermal/thermal_zone0/mode' to /etc/rc.local (before the "exit 0"-line)."

[Neil Wilson (neil-aldur)]

You can do

sudo sh -c 'echo -n "enabled" > /sys/class/thermal/thermal_zone0/mode'

as a single line workaround.

I am using an Acer Aspire One 110L (8.9" display, 8GB SSD) and have activated acerhdf as default by supplying this file

/etc/modprobe.d/acerhdf.conf

see attachement. Works reliably and smoothly for several weeks now.

content:

# fan control for acer aspire one fan
# according to: http://piie.net/files/acerhdf_README.txt
# check status with: dmesg|grep acerhdf
# read temperatur with: cat /sys/class/thermal/thermal_zone0/temp
options acerhdf interval=5 fanon=60 fanoff=55 kernelmode=1

[Zimmer (canadianclub)]

Sorry, am a linux newbie here, and have just got Ubuntu netbook version installed on my aspire one from a usb stick, and all working perfect, so I don't wanna mess it up.
To do this fan mod, how exactly do I use the above attachment, in simple steps please, as I know nothing about Linux (yet), but so far I like what I see.

[Sokraates (sokraates)]

Zimmer: You will need to copy the file (acerhdf.conf) into the folder /etc/modprobe.d

The folder etc/ and its contents can only be edited by a super-user. To do this graphically, you will need to start Nautilus as root (of course, you could also do this through the command line, but this is easier for starters).

Unless Ubuntu provides a link in the application menue, to open Nautilus as super-user/root (I don't know, since I don't use GNOME) you will need to open a terminal (the application) and type "gksu nautilus".

A window will pop-up, asking for your password (your regular user password) and then you will have a nautilus open, wherein you can move and edit all files on your system. So be *VERY* careful, what you do.

[Dmitry Kann (yktooo)]

I confirm it is disabled by default, although it itself recommends to execute 'echo -n "enabled" > /sys /class/thermal/thermal_zone0/mode', you can see it if you run:
dmesg|grep acerhdf

[Neil Wilson (neil-aldur)]

Note that in Lucid the temperature is in millidegrees, not degrees, so the 'fanon' and fanoff' thresholds need to be set accordingly.

I just go with the defaults and have

options acerhdf verbose=1 kernelmode=1

in my /etc/modprobe.d/acerhdf.conf file.

(The verbose shows you what the fan controller is doing).

Bug still present in maverick 10.10 on PackardBell ButterflyTouch / Acer 1825.
Please enable acerhdf by defalut.

[lianergoist (tj001)]

Yes, please enable acerhdf by defalut.
