I have an AMD Radeon HD 6310 with free radeon drivers running. Xorg version is
7.6, xserver is 1.10.3.

I tried to define a udev rule to change my monitor settings automatically when
I connect a VGA or an HDMI cable. Connecting works fine but disconnecting is
not recognized.

udevadm monitor shows:

udevadm monitor

monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

KERNEL[100.176249] change   /devices/pci0000:00/0000:00:01.0/drm/card0 (drm)
UDEV  [100.869104] change   /devices/pci0000:00/0000:00:01.0/drm/card0 (drm)

for connecting. For disconnecting nothing happens. 

I hope this is the right place to file this as a bug.

Every help is appreciated!
