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/1290517 Title: Asus R751L Notebook - Touchpad not recognized Status in linux package in Ubuntu: Confirmed Bug description: I made a fresh install of ubuntu 13.10.
