Hello, After noticing following logs in my dmesg: psmouse serio2: synaptics: Your touchpad (PNP: SYN1221 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@xxxxxxxxxxxxxxx. psmouse serio2: synaptics: Touchpad model: 1, fw: 8.2, id: 0x1e2b1, caps: 0xf00223/0x840300/0x26800/0x0, board id: 3175, fw id: 2330500 I booted with the mentioned kernel parameter but unfortunately resulted in my touchpad not working. Some of the logs with the parameter: psmouse serio2: synaptics: queried max coordinates: x [..5718], y [..4908] psmouse serio2: synaptics: queried min coordinates: x [1238..], y [956..] psmouse serio2: synaptics: Trying to set up SMBus access Nov 26 10:33:07 shalzz-galp2 kernel: i801_smbus 0000:00:1f.4: Timeout waiting for interrupt!
