(In reply to Balazs Nagy from comment #14) > Kernel 4.1.12 (vanilla) does not help, no support for this touchpad. Which machine are you using? Fujitsu H730 is supported in 4.1.x. Fujitsu T725 seems some fix in addition in 4.2. Also, there is another fix for pre-v4 elantech device in 4.2. Both patches look easy to backport, so I can prepare a test kernel later, once when you confirmed that it works with 4.2 kernel.
