                          I'm seeing the following warning in dmesg:

    [    2.631179] psmouse serio2: synaptics: Your touchpad (PNP: SYN1218 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.
    ...
    [    2.819449] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio2/input/input10

The touchpad works, but I feel that it is not working as well as it used to. I'm on Gentoo with a custom configured kernel. I've recently switched to other distros and came back to Gentoo and reconfigured the kernel from the ground up. I don't believe I did something out of the ordinary with regards to the input devices, so this *might* be a bug as suggested in dmesg.

**My question**: how do I check if those are not used?

> you might want to try setting psmouse.synaptics_intertouch to 1

    $ sudo sysctl -a | grep "psmouse.synaptics_intertouch"

Returns nothing, so nothing to set there.
