My touchpad is an Alps I2C:
cat /proc/bus/input/devices:
I: Bus=0018 Vendor=044e Product=121e Version=0100
N: Name="AUI1667:00 044E:121E Mouse"
P: Phys=i2c-AUI1667:00
S: Sysfs=/devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-1/i2c-AUI1667:00/0018:044E:121E.0001/input/input3
U: Uniq=
H: Handlers=mouse0 event3
B: PROP=0
B: EV=17
B: KEY=70000 0 0 0 0
B: REL=1943
B: MSC=10
And touchpad gestures will not work, and I do not know how to solve it. I tried changing some mouse-related settings in both Settings and in Gnome Tweaks.
