Comment 74 for bug 636311

@Chris Halse Rogers:

Mouse only moves to 0,0 the first time a special key is pressed after log in. After that, the mouse is unaffected.

My results from input-events:

/dev/input/event12
   bustype : BUS_USB
   vendor : 0x45e
   product : 0x745
   version : 273
   name : "Microsoft Microsoft® 2.4GHz Tra"
   phys : "usb-0000:00:1d.7-1.4/input2"
   uniq : ""
   bits ev : EV_SYN EV_KEY EV_REL EV_ABS EV_MSC EV_REP

waiting for events
11:32:24.756207: EV_MSC code=4 value=786665
11:32:24.756223: EV_KEY KEY_VOLUMEUP (0x73) pressed
11:32:24.756267: EV_SYN code=0 value=0
11:32:24.844234: EV_MSC code=4 value=786665
11:32:24.844250: EV_KEY KEY_VOLUMEUP (0x73) released
11:32:24.844297: EV_SYN code=0 value=0

Perhaps uninteresting, but I did an input-events on my mouse at the same time it moved to 0,0, but there was no output. ie: input-events didn't register the mouse movement.
