"psmouse.synaptics_intertouch=1" fails on Lenovo T14 AMD

[Michał Kopeć]

Hello,

I found the following messages in dmesg on my Lenovo Thinkpad T14 AMD
and I'm following the suggestion to report them here:

[    1.664239] psmouse serio1: synaptics: queried max coordinates: x
[..5678], y [..4694]
[    1.703482] psmouse serio1: synaptics: queried min coordinates: x

[    1.703492] psmouse serio1: synaptics: Your touchpad (PNP: LEN2064

are not used, you might want to try setting
psmouse.synaptics_intertouch to 1 and report this to
linux-input@vger.kernel.org.

However, booting with "psmouse.synaptics_intertouch=1"  results in the
following messages:

[    1.872540] input: SynPS/2 Synaptics TouchPad as

after which the touchpad works in exactly the same way as when booted
without the parameter.

My kernel is compiled with HID_I2C and HID_RMI enabled. Am I missing
some configuration here or is this expected behavior?
Please let me know if there's any additional relevant information I can provide.

Thanks and best regards,
