Public bug reported: Using Kubuntu Netbook remix on an AAO 110. All updates as of 16.08.2009.
Acerhdf works well and diligently starts on every boot after being added to /etc/modules, however it will not take effect since fan control is disabled by default in /sys/class/thermal/thermal_zone0/mode. 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). I've tried this with acerhdf 0.5.13 up to 0.5.17 (which I currently use) and kernels 2.6.31-5 and 2.6.31-6. Smae problem, same fix/workaround. Concerning enabling fan control I consider this a fix, however I doubt that the line should be added to /etc/rc.conf. Rather /sys/class/thermal/thermal_zone0/mode should remember the changes (I guess). I have not had similar problems on this machine running Jaunty UNR and KDE 4.3 (from backports). There acerhdf only needed to be added to /etc/modules to have it work after a reboot or shutdown. ** Affects: ubuntu Importance: Undecided Status: New -- [KDM] Acerhdf not working due to fan control being disabled (with fix/workaround) https://bugs.launchpad.net/bugs/414882 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
