Public bug reported:
1.Laptop model: LENOVO Thinkpad x120e 0611-AE5
2.Manufacturer of the Touchpad: Synaptics
3.When the symptom first appeared: around 3 month ago (August 2017)
I first encountered this issue after dual boot Linux Ubuntu-MATE 16.04
LTS and Windows 10. My system always update. Touchpad suddenly not
working when the laptop woke up from sleep in Windows 10 OS.
Tried to add parameters in GRUB: quiet splash i8042.reset i8042.nomux=1
i8042.nopnp=1 i8042.noloop=1 without any positive result (touchpad still
not working), but, now xinput detect PS/2 Generic Mouse for touchpad
(before touchpad is not detected at all).
Attached dmesg and devices file.
Thanks.
Regards,
