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)." -- acerhdf: not enabled by default https://bugs.launchpad.net/bugs/436768 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
