Public bug reported: After login, the touchpad is detected and shown in xinput --list and in /proc/bus/input/devices. But any movements or clicks are not detected.
The really weird part is that the touchpad STARTS working after waking from suspend. The touchpad works flawlessly in Windows 10 (didn't work in Windows 7), and external mice also work in both Ubuntu and Windows. The problem happens in Ubuntu 16.04, Ubuntu 14.04 didn't detect the touchpad at all in xinput and /proc/bus/input/devices. I have tried several GRUB command line parameters that I've seen recommended on the internet, such as i8042.reset=1 i8042.nomux=1 i8042.noloop=1 psmouse.proto=bare, but none of them changed anything the touchpad didn't work when the system boots up, but it starts working after suspend. I've attached the outputs from xinput --list, /proc/bus/input/devices and synclient. The outputs don't change when I suspend and wake up the computer, the list of modules in lsmod also doesn't change.
