On the TUXEDO Book BU1406, since Linux 4.12, the Linux kernel logs the
message
below.
```
kernel: psmouse serio1: synaptics: Your touchpad (PNP: SYN1217 PNP0f13)
says it can support a different bus. If i2c-hid and hid-rmi are not
used, you might want to try setting psmouse.synaptics_intertouch to 1
and report this to linux-input@xxxxxxxxxxxxxxx.
```
Booting with `psmouse.synaptics_intertouch=1`, the touchpad continues to
work, so add the ID of the device to the list of IDs, whose devices
support I2C mode.
