SYNA7DB5 Touchpad don't works

Hello everyone,

I installed Arch on my laptop Acer Aspire E5 575G a few months ago, and my touchpad can click, but can't move the cursor. I unchecked the option "Disable when mouse is connected" but it didn't change anything. With the command "cat /proc/bus/input/devices", I get :
I: Bus=0018 Vendor=06cb Product=7db7 Version=0100
N: Name="SYNA7DB5:00 06CB:7DB7 Touchpad"
P: Phys=i2c-SYNA7DB5:00
S: Sysfs=/devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-5/i2c-SYNA7DB5:00/0018:06CB:7DB7.0006/input/input27
U: Uniq=
H: Handlers=event9 mouse1
B: PROP=5
B: EV=1b
B: KEY=e520 10000 0 0 0 0
B: ABS=2e0800000000003
B: MSC=20

I found a script (https://github.com/mirko-laruina/i2c_SYNA7DB5_fix) on github who is removing the I2C controller from the PCI bus and adding it back. It works until I don't move my cursor for a few seconds, then it returns like before. I tried to reload the driver :
modprobe -r hid_multitouch
modprobe hid_multitouch
But it didn't change anything too.
I don't know what to do. Thanks for your help, and sorry for my trash english
