Comment 10 for bug 1590590

The same for me in E5470:

xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ImPS/2 Generic Wheel Mouse id=12 [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=11 [slave keyboard (3)]
    ↳ Dell WMI hotkeys id=13 [slave keyboard (3)]
    ↳ DELL Wireless hotkeys id=14 [slave keyboard (3)]

Tried installing the psmouse-alps-1.3 driver, the install was successful, but nothing changed.

An additional problem is that since there are no touchpad settings in System Settings, I cannot change the "Disable touchpad while typing". I tried dconf, but there is no such option neither. The "Disable touchpad while typing" seems to be on -- the touchpad disables for ~1 sec after touching any key (including Shift for instance). I tried using syndaemon -i 1.0 -K -R -t with no effect neither.
