Bug description:
Newer versions of the Elantech multitouch trackpad are not fully
supported in Linux. These appear in many of the newer Samsung
laptops, for example. elantech.c in the kernel needs to be updated to
support these models (up to v7 perhaps?)
This bug is confirmed to affect a range of samsung laptops running
Ubuntu 12.04 and newer, ArchLinux, Fedora and also affects the current
(3.9) upstream kernel.
A dkms package was produced in 2011 (see
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-
intel/+bug/681904/comments/64) which may fix certain older laptops
affected by this issue, but doesn't fix newer models.
== Original Report ==
Hello,
So far I've been having a problem with my Elantech multitouch trackpad in Linux. Basically all i get is right click, left click, and tap to click, along with basic movement. The problem seems to be rooted in improper detection of the trackpad, likely b/c its a new revision or whatnot. Of note is that working elantech trackpads of the past in forums i scouted through show up as "ETPS/2 Elantech Touchpad". Mine just shows up in xinput as "PS/2 Elantech Touchpad". I think this might be a simple fix in the end, just improper detection, I hope. For reference, I've tried kernel 3.5 on Ubuntu 12.10 and kernel 3.8.0-17 on Ubuntu 13.04 thus far, with all combinations of psmouse.
------------------------------------------------------------------------------------------
What's expected: touchpad multitouch support
What happened: basic touchpad support
Laptop mode: Samsung Series 7 NP780 series
Ubuntu distro(s) tested: Ubuntu 12.10, Ubuntu 13.04
Kernels used: 3.5 signed (Ubuntu 12.10 default), 3.8.0-16, 3.8.0-17 signed
Other tests: Attempted using psmouse-elantech-v6, psmouse-alps, and psmouse-alps-dst. No improvements so removed.
synclient -l reports "Couldn't find synaptics properties. No synaptics driver loaded?"
