Bug Description

The touchpad on my HP 1011 Elite X2 G1 is showing as a PS/2 mouse after installation in xinput. Multitouch gestures do not work and installing xserver-xorg-input-synaptics did not resolve the issue. The touch pad uses the Synaptics driver in Windows 10.

Other functionalities of the keyboard do work such as enabling/disabling wireless and volume up/down.

The touchpad should be able to use multitouch for two-finger scrolling and two-finger tap for right click but instead only single touch inputs are accepted for left and right click. No multitouch gestures are recognized.

Current version is Ubuntu 4.15.0-43.46-generic 4.15.18 on Ubuntu 18.04.1 LTS.

The dmesg contains full of "System PCM: error: failed to commit stream -110", no touchpad related message can be found.

After performing another apt-get upgrade today the dmesg output provides more information including information on the PS/2 input being recognized.

I see this section specifically showing the touchpad not being recognized correctly:
