I am experiencing the same behavior with the 4.19 kernel. The touchpad does not work smoothly and freezes occasionally and I have to wait for couple of minutes, after which it starts working again.
dmesg command gives the same output like what other people have reported: i2c_hid i2c-ELAN1200:00: i2c_hid_get_input: incomplete report (16/65535) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1778087 Title: ELAN1200 touchpad jumps around and disconnects To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1778087/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
