Comment 12 for bug 784965

Maybe this info will be useful for us...
This is the standard situation on my vaio sb:

$ xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Mouse id=12 [slave pointer (2)]
⎜ ↳ AlpsPS/2 ALPS GlidePoint id=13 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
    ↳ Video Bus id=6 [slave keyboard (3)]
    ↳ Sony Vaio Keys id=7 [slave keyboard (3)]
    ↳ Video Bus id=8 [slave keyboard (3)]
    ↳ Power Button id=9 [slave keyboard (3)]
    ↳ USB 2.0 Camera id=10 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]

I've attached the output of the commands "xinput list-props 12" and "xinput list-props 13"

Particularly:

$ xinput list-props 12
 Device Enabled (126): 1
......
$ xinput list-props 13
 Device Enabled (126): 1
......

Hope you will resolve this frustrating bug...
