Hello,

I am reporting a touchpad issue and behavior on my Lenovo ThinkPad T470s.

System:

  * Laptop: Lenovo ThinkPad T470s
  * OS: Fedora 44
  * Kernel: 6.19.14-300.fc44.x86_64

Kernel message:
psmouse serio1: synaptics: Your touchpad (PNP: LEN007f 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

Observed behavior:

  * Without |psmouse.synaptics_intertouch=1|:
    The touchpad works initially, but after some time it randomly freezes.
    When this happens, the touchpad becomes unresponsive and I need to
    log out and log back in to restore functionality.
    The issue is intermittent but happens regularly.
  * With |psmouse.synaptics_intertouch=1|:
    The touchpad works reliably with no freezes so far.

Please let me know if further testing or logs are needed.

Thanks
