On a Dell XPS 13 9310, Linux 5.9.1 from Debian Sid/unstable displays the
message below.

      [    2.218614] psmouse serio1: synaptics: Your touchpad (PNP: DLL0991 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@vger.kernel.org.

I am going to ask the user for a test of
`psmouse.synaptics_intertouch=1`, so the ID can be added to the force
list, but until know no Dell DLLXXXX ids show up there.

I happen to have one of these on my desk and on 5.10-rc1 I don't see this behavior:

Can you please make sure that pinctrl_tigerlake is loaded?

Debian’s Linux configuration does not build the driver.

     # CONFIG_PINCTRL_TIGERLAKE is not set

I reported bug *linux: Select PINCTRL_TIGERLAKE to support current 
hardware* to Debian bug tracking system [1].

Thank you very much.


Kind regards,

Paul
