Hi, I had a Thomson X6 notebook, it's seems to be a Jumper Ebook 3 Pro rebranded.
I compiled original kernel from kernel.org. - With 4.14 RC7 version, movements, simple ou double tab click, 2 finger gesture worked. But click buttons not. - With 4.14 RC8 version, nothing works anymore ! I did some investigations. I copied the "drivers/base" files from 4.14 RC7 to 4.14 RC8. I compiled the custom kernel... and it works again (except click buttons). - I did the same thing with the latest version currently available (4.14.41), I had the same behavior. - With 4.16 version, after startup/reboot, the touchpad is recognized in log (dmesg) but it's not work. So, if I suspend and resume, gestures and even buttons are working ! - From my 4.14.41 version already patched ("drivers/base" files from 4.14 RC7), I copied "drivers/hid" and "drivers/input" files from 4.16. Now, everything works : gesture and buttons after a first startup and after suspend/resume. I don't know if "drivers/input" files modifications are really necessary, I will do a rollback and test later. Obviously, I can't compile kernel if I replace files without minor modifications. I analyzed the code changes (drivers/base) between the 4.14 RC7 and 4.14 RC8 versions. There are only a few lines that have been modified. So I made the reverse modifications in version 4.16, but without success. Touchpad is still not work after startup/reboot but works only after suspend/resume. In all versions (4.14 RC7 original, 4.14 RC8 and 4.14.41 modified, 4.16 original), I still have error messages : [ 6.326589] i2c_hid i2c-SYNA3602:00: i2c_hid_get_input: incomplete report (32/261) [ 6.328725] i2c_hid i2c-SYNA3602:00: i2c_hid_get_input: incomplete report (32/8713) [ 6.329796] i2c_hid i2c-SYNA3602:00: i2c_hid_get_input: incomplete report (32/261) [ 6.333024] i2c_hid i2c-SYNA3602:00: i2c_hid_get_input: incomplete report (32/23334) [ 6.334090] i2c_hid i2c-SYNA3602:00: i2c_hid_get_input: incomplete report (32/20745) [ 6.337295] i2c_hid i2c-SYNA3602:00: i2c_hid_get_input: incomplete report (32/31302) [ 6.338385] i2c_hid i2c-SYNA3602:00: i2c_hid_get_input: incomplete report (32/29952) [ 6.342743] i2c_hid i2c-SYNA3602:00: i2c_hid_get_input: incomplete report (32/22281) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1728244 Title: Touchpad stops working after reboot on Apollo Lake To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1728244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
