[Touchpad] Tap-to-click and two-finger right-click only work randomly

Hi everyone,

I’m running Arch Linux on a Lenovo ThinkPad T14 Gen 1 (Intel i5-10210U) and facing a strange issue with the Synaptics TM3471-020 touchpad under the psmouse kernel module.

The touchpad is always detected at boot.

Cursor movement and two-finger scrolling always work.

Tap-to-click and two-finger tap for right-click only work sometimes.

Reloading the driver fixes it (may take only one reload sometimes but mostly it takes multiple reloads to works ):

sudo modprobe -r psmouse && sudo modprobe psmouse

After reloading, all features (including taps) start working perfectly.

This happens intermittently on every reboot — it seems like psmouse sometimes loads the device in generic PS/2 mode instead of full Synaptics mode.

I can confirm that touchpad behaves very randomly and sometimes doesn't interpret tap-to-clicks, as well as faster finger movements which are essentially lost.
In my case, the suspend and reboot actions are essential for the touchpad to start (or stop) working correctly - it has never broken during the "awake state".

For me, reloading psmouse module also fixes the issue, but often it takes more than one reload in a row to get right.

What I had recently discovered is that in case of linux-lts kernel, reloading the i8042 module also seems to fix the issue (sometimes, like reloading psmouse).

I am yet to find a long-term, sufficient fix.

Any help would be sincerely appreciated!

What DE do you have? I used to use XFCE and had an issue similar to this one.
