Exactly, these are oneliners. There is no the GPU fan here, so I tested the CPU fan, and this is how it works: /etc/udev/rules.d/10-cpu-fan-manual-mode.rules RUN+="/bin/sh -c '/bin/echo 1 > /sys/devices/platform/it87.656/pwm1_enable'" Therefore remove ACTION & ATTRS part, so it runs unconditionally. Before you reboot, check with: # udevadm trigger</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
