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 [email protected].
...
[ 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
.

If i2c-hid and hid-rmi are not used
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.
