This has not worked with any kernel I've tried, from 4.15 to 4.18 to the upstream 4.19 you linked to.
Here's some relevant dmesg output from the v4.19: [ 1.390898] i2c_hid i2c-ELAN469D:00: i2c-ELAN469D:00 supply vdd not found, using dummy regulator [ 1.390914] i2c_hid i2c-ELAN469D:00: Linked as a consumer to regulator.0 [ 1.390915] i2c_hid i2c-ELAN469D:00: i2c-ELAN469D:00 supply vddl not found, using dummy regulator [ 2.420872] i2c_designware AMDI0010:01: controller timed out ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Tags added: kernel-bug-exists-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1795292 Title: ELAN469D touch pad not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1795292/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
