Using pwm_enable as a master configure > (off/manual/auto) makes sense to me. I thought that pwm_enable would be the master command, ie: pwm = 0: fan to full speed pwm = 1, auto_channels = 0: manual pwm pwm = 1, auto_channels > 0: auto pwm But I didn't consider the pwm scripts. Would it be complicated to update these scripts according to the model I propose? -- Jean Delvare http://khali.linux-fr.org/
