[Bug 1506363] Re: Touchpad die after resume from suspend(s2ram)
** Tags added: apport-collected
** Description changed:
Hardware : ASUS K401L (K401LB5200)

When the system startup, the touchpad works well, but after it resumed
from a suspend, the touchpad hardware will disappear from xinput and
cat /proc/bus/input/devices.
Before suspend, xinput output
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ USB OPTICAL MOUSE id=10 [slave pointer (2)]
⎜ ↳ ETPS/2 Elantech Touchpad id=14 [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)]
↳ Video Bus id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ USB2.0 VGA UVC WebCam id=11 [slave keyboard (3)]
↳ Asus WMI hotkeys id=12 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]
after suspend, the output
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ USB OPTICAL MOUSE id=10 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]

↳ USB2.0 VGA UVC WebCam id=11 [slave keyboard (3)]
↳ Asus WMI hotkeys id=12 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]
And you can find that the " ETPS/2 Elantech Touchpad" is missing
After a reboot, everything works well again.
