Description of my bug is mouse does not work at all. Device is elantech ETD0108. Laptop is Asus TP500LN. Dmesg gives "lost sync at byte 6" messages. Mouse does work with proto=imps parameter but no two-finger functionality. If this is the same with you, after sudo su try echo 1 > /sys/devices/platform/i8042/serio4/reg_07 (or serioX?) and see if it fixes the issue.
For at least asus TP500LN a kernel patch is under consideration https://bugzilla.kernel.org/show_bug.cgi?id=84491 https://www.marc.info/?t=142731893400011 Many thanks to Ulrik de Bie! Perhaps you can post on bugzilla that it affects your laptop too. ** Bug watch added: Linux Kernel Bug Tracker #84491 http://bugzilla.kernel.org/show_bug.cgi?id=84491 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1379450 Title: Touchpad on ASUS X750LN notebook doesn't work on Ubuntu Status in linux package in Ubuntu: Triaged Bug description: The touchpad on my ASUS X750LN notebook (modell R751LN-T4102H) doesn't work on Ubuntu 14.04.1 LTS. It seems to me, that the touchpad is not recognized by linux. It works completely under Windows 8.1. An USB mouse works fine under linux. The keyboard Fn key also doesn't work on linux. On Windows I found this information, which may be helpful. It is not the original text since I translated it from german.
