I am having problems with my Touchpad Elantech on Acer Aspire E1-572G. I tried both Ubuntu 16 and 17 (and also other Linux distros), but no luck. My problem is that the gestures (two-finger tap for right click and two-finger scroll) are actually working, but not in a smooth way. For example, on average, I have to do the two-finger tap 2 or 3 times before I get it right, and I have to be VERY careful to hit the pad with the two fingers exactly in the same time, other wise it doesn't work. It's annoying and it slows me down a lot. I just switched from Windows 10 and over there the touchpad gestures were a LOT smoother, never had to do them more than one time. I'm wondering if there's any possibility to use the Windows drivers on Ubuntu, or any other workaround. Here's a video comparison of my Elantech touchpad on Windows 10 and on Ubuntu 17.10, to clearify what my problem is: https://youtu.be/L6SBWJpAT5A Scrolling is laggy and it doesn't always work, positioning the pointer for small movements is difficult, and the two-finger tap for right click is almost unusable. Thank you for your help.
Please attach an evemu-record from a two-finger tap sequence that didn't get detected.

was that really a two-finger tap? The reason I'm asking is: E: 0.000001 0001 014e 0001 # EV_KEY / BTN_TOOL_TRIPLETAP 1 This line indicates that the device thought there were 3 fingers down on the touchpad, that would then trigger a middle click in the default confing. If this was really a two-finger tap, then we have a problem with the touchpad firmware and the kernel drivers.

yes, it was. to make sure, i recorded other two undetected two-finger taps. I'm attaching the logs to this comment. they both show: # EV_KEY / BTN_TOOL_TRIPLETAP 1 but i never touched they trackpad with three fingers!
CC-ing Benjamin, this is a kernel bug/firmware issue if the touchpad detects three fingers when there are none. Please attach a dmesg, thanks.
Yes, ok. I'm attaching the dmesg output. I hope I did it correctly. Thank you for your time.

You know what? I'm sick of this bull***t. I wasted enough time trying to fix stupid linux problems. I'm going back to a cracked Windows 10 and that's it.
no point keeping the bug open then
