Touchscreen not working after kernel update (Chuwi surbook mini)

[ThiBsc]

Hi,

I have a Chuwi Surbook and I install an Ubuntu Gnome 16.04 LTS. Everything works fine on the first kernel:

# uname -r
4.13.0-41-generic

But after an apt update the kernel is 4.13.0-43-generic don't work with the acpi driver.
So I have try to go back on the first kernel by doing

apt purge linux-image-4.13.0-43-generic

But it still no work. Here the result of my dmesg:

[  142.265170] gslx680 i2c-MSSL1680:00: gsl_ts_probe: got a device named MSSL1680:00 at address 0x40, IRQ 143, flags 0x0
