Hi, my kernel log tells me I could try to set psmouse.synaptics_intertouch to 1 and report it. kernel: psmouse serio1: synaptics: Your touchpad (PNP: DLL060d 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. As i2c-hid and hid-rmi modules are not used I added "psmouse.synaptics_intertouch=1" to the kernel command line and reboot the system. After that the message does not appear anymore. AFAIK my touchpad works before and after that change without any problems. At least I did not realize any. Without enabling intertouch the kernel message looks like: May 01 18:44:01 m3800.localdomain kernel: psmouse serio1: synaptics: queried max coordinates: x [..5660], y [..4646] May 01 18:44:01 m3800.localdomain kernel: psmouse serio1: synaptics: queried min coordinates: x [1386..], y [1252..] May 01 18:44:01 m3800.localdomain kernel: psmouse serio1: synaptics: Your touchpad (PNP: DLL060d PNP0f13) says it can support a different bus.

Hopefully the report is helpful for you. Best regards, Markus
