Hi, on my Thinkpad T460s my Kernel (4.12.8 built from gentoo-sources) told me about my Touchpad supporting a different bus. After building all the related modules, the message stayed, so I did as the message told and set psmouse.synaptics_intertouch to 1, it then used the rmi_smbus module. Feel free to contact me, if you need more information. Regards, Markus Aug 18 04:29:59 Lhotse kernel: psmouse serio1: synaptics: Your touchpad (PNP: LEN004b 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.
