    What about better touchpad support? Some touchpads provide different protocols/buses just for compatibility reasons. ps/2 emulation, i2c/smbus.

    I wonder if it's better to use the most native bus/protocol rather than the "emulated" one. If it is... Would the kernel automatically choose the best one?

      If you mean the version best supported by the kernel, then that is likely. If you mean the absolute best for each device, it depends on driver support.

        After one year and a half, ELAN touchpad (ELAN1203:00 04F3:3043) is still completely dead on ASUS ROG G752 laptop series:
        https://bugs.launchpad.net/ubuntu/+s...x/+bug/1653456

        It has been recently reported that the Anaconda pre-installation setup of Fedora 28 Atomic Workstation is one and unique first time ever that "ELAN1203:00 04F3:3043" touchpad is working. In other words, regardless of whether Asus G752 owner use any other Fedora Atomic Workstation release, normal Fedora (version 28 included) or any other Linux distribution - "ELAN1203:00 04F3:3043" touchpad is always completely dead. After the installation of the Atomic Workstation 28 it is also dead.

          General service announcement (not necessarily talking to you as I don't know who reported the bug there and if this was also reported upstream), it's better to post kernel bugs in the upstream kernel bugtracker, as that's where kernel developers can actually see them.

          Ubuntu bugtracker isn't going to help anyone.

            That dial thingy is pretty neat, assuming the application actually does have support for it. I know it is totally a vendor lock-in bait, but it is probably the only new human interface device I've seen in a while that actually makes some sense.
