Dear linux-input,
I was having some issues with my touchpad on my Lenovo Thinkpad T15 (gen 2), after reading some log messages, I noticed something among the lines of:
```
psmouse serio2: synaptics: Your touchpad 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@xxxxxxxxxxxxxxx.
```
Both of the mentioned modules were not loaded by default.
So I decided to set the intertouch option in the grub config, and after a swift reboot I verified if the intertouch value had indeed changed:
```
cat /sys/module/psmouse/parameters/synaptics_intertouch
1
```
The touchpad is now noticeably more responsive and less jittery, hence this email to report my findings.
As for the details:
- Hardware: Lenovo Thinkpad T15 (Gen 2)
- Distribution: Ubuntu 22.04.2 LTS
- Kernel: 5.19.0-45-generic
- Touchpad:
```

product: Synaptics TM3471-030
physical id: 4
logical name: input11
logical name: /dev/input/event9
logical name: /dev/input/mouse0

```
If there is more information required, feel free to ask, I am happy to help!
Kind regards,
L. van Teeffelen
