Apparently, > the EeePC safe mode is the same as automatic mode. So when we write "0" to > pwm1_enable, if we read it again, we'll see "2". This is a bug in the eeepc driver. If it doesn't support mode 0, it should return -EINVAL when one tries to set it. > I could find information about EeePC fan control here: > https://patchwork.kernel.org/patch/64435/ > > To enable automatic mode at exit, I changed fancontrol with the following > patch: > > > --- /tmp/fancontrol 2010-04-25 09:31:58.394184626 +0200 > +++ /usr/sbin/fancontrol 2010-04-25 09:21:24.161183983 +0200 > @@ -318,7 +318,7 @@ > > # Try pwmN_enable=0 > echo 0 > $ENABLE 2> /dev/null > - if [ `cat $ENABLE` -eq 0 ] > + if [ `cat $ENABLE` -ne 1 ] > then > # Success > return 0 > > > Do you think this change is worth including it for the next version of > lm-sensors ? No. What needs to be fixed is the eeepc driver. We don't want to add random quirks to user-space applications to work around kernel driver bugs. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
