Solved: Udev rules not working

I have file called "/etc/udev/rules.d/99-monitor-hotplug.rules" with this rule:

ACTION=="change", SUBSYSTEM=="drm", RUN+="/root/scripts/hotPlugMonitor.sh"

But hotPlugMonitor.sh-script is not ran even thought it has permission to be ran and

udevadm monitor --property

gives:

KERNEL[69983.904205] change   /devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card0 (drm)
ACTION=change
DEVNAME=/dev/dri/card0
DEVPATH=/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card0
DEVTYPE=drm_minor
HOTPLUG=1

MINOR=0
SEQNUM=1885
SUBSYSTEM=drm

UDEV  [69983.905420] change   /devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card0 (drm)

when I detach my monitor.

Re: Solved: Udev rules not working

udevadm control --reload-rules
udevadm trigger

Didn't work, but after reboot everything started work.

Re: Solved: Udev rules not working

You got the command slightly wrong. See the right command:

udevadm control --reload

From:

$ udevadm control --help | grep reload
  --reload                 reload rules and databases
