I have a system that matches the original reporter's system except for the machine's manufacturer that in my case is ASUS, for the Elantech's complete hardware string that in my case is 0x381f00, and for the kernel version that in my case is 3.11.0-22-generic.
I confirm that Matthew Walker's patch in comment #15 works fine. -- 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/1232877 Title: [Aspire S7-392] Touchpad reported as: "elantech: unknown hardware version, aborting" Status in “linux” package in Ubuntu: Confirmed Bug description: Only basic functionality (right/left click, moving pointer) work. Expectation is that the device would be detected as a touchpad with support for multitouch/scrolling/etc. The laptop is an Acer S7 392.
