I had the same problem. I guess you also made a udev rule to create /dev/input/mx1000. But looking at the manpage Option "Device" is discouraged:
Option "Device" "string" Specifies the device note through which the device can be accessed. This will generally be of the form "/dev/input/eventX", where X is some integer. The mapping from device node to hardware is system-dependent. Please note that use of this option is discouraged. So I changed this: Section "InputDevice" Identifier "Logitech MX1000" Driver "evdev" Option "CorePointer" Option "Device" "/dev/input/mx1000" EndSection into this: Section "InputDevice" Identifier "Logitech MX1000" Driver "evdev" Option "CorePointer" Option "Name" "Logitech USB Receiver" EndSection And all was fine again.
