Public bug reported: I have just bought a new laptop from Teclast model F6 Pro. I have installed Ubuntu LTS 18.04.2 (kernel 4.18.0-16-generic).
The Goodix touchpad of the laptop is not recognized by the kernel version used by Ubuntu LTS 18.04.2. That is my kernel error: [ 3.733842] i2c_hid i2c-SYNA3602:00: i2c-SYNA3602:00 supply vdd not found, using dummy regulator [ 3.738296] i2c_hid i2c-SYNA3602:00: unexpected HID descriptor bcdVersion (0x0000) The problem is known, it is described here: https://bugzilla.redhat.com/show_bug.cgi?id=1526312 A patch is available here: https://github.com/brotfessor/sipodev/blob/master/b/i2c-hid.c It looks like that patch entered in the mainline kernel since 4.20 (or 4.19 I am not sure). It would be very helpful if that patch is added to Ubuntu 18.04.2 LTS 4.18.0-16-generic kernel to help the users of Teclast laptops like me. On several Teclast laptops the touchpad is not supported on Unbuntu 18.04.2 (for sure F6 pro and F7).
