Comment 4 for bug 1294466

I have the same problem on a Dell Inspiron 14. syndaemon just won't disable the touchpad while typing, no matter what I do.
Running syndaemon in verbose mode shows that it does actually try to enable and disable the touchpad but nothing happens.
I think it might be related to the fact that there are two touchpads in this laptop as reported by xinput:

$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ DLL063E:00 06CB:2934 id=11 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=13 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
    ↳ Power Button id=6 [slave keyboard (3)]
    ↳ Video Bus id=7 [slave keyboard (3)]
    ↳ Power Button id=8 [slave keyboard (3)]
    ↳ Sleep Button id=9 [slave keyboard (3)]
    ↳ Integrated_Webcam_HD id=10 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)]
    ↳ Dell WMI hotkeys id=14 [slave keyboard (3)]

Presumably syndaemon is disabling the SynPS/2 device while the actual touchpad is the DLL063E:00 device. Funnily enough enough the "Mouse and Touchpad" settings works on the right device.
