Description Jamie Kitson 2012-06-25 03:02:27 UTC
With my Sentelic touchpad two finger scrolling and two finger tapping interfere with each other. ie, if you disable one, the other works as expected. I tried to report this against the kernel driver but they said that the kernel doesn't deal with scrolling/tapping.

Please grab mtview from https://github.com/whot/mtview and check if the data that comes from the touchpad looks sane (no weird jumps, etc.)

If so, please record the device data with utouch-evemu and attach both the description and event file here. Try to get as short a recording as possible to reproduce.
Comment 2 Jamie Kitson 2012-06-26 14:53:48 UTC
mtview looks fine, but for some reason I am now unable to enable double finger tapping, meaning that I cannot recreate the bug.

Two finger scrolling

Output of

evemu-record /dev/input/event7

while two finger scrolling

Issue is that scroll doesn't happen until I lift my fingers off the touchpad.

Two finger tap

Two finger tapping doesn't work either.
Comment 6 Jamie Kitson 2012-06-27 13:16:32 UTC
After a cold start today the touchpad was playing up again.
Comment 7 Jamie Kitson 2012-06-27 13:37:41 UTC
I think I've narrowed it down to horizontal and vertical two finger scrolling that are interfering with each other. If I enable both then it's erratic, if I only enable vertical it's ok.

Two finger taping still doesn't work though.

This is possibly an issue with the driver: https://bugzilla.kernel.org/show_bug.cgi?id=43591#c5
Comment 9 Peter Hutterer 2016-11-28 04:40:03 UTC
This is a mass change of bugs. Bugs assigned to me that haven't been updated in the last 3 years are closed as WONTFIX, because, well, let's at least be honest about it.

Please do not re-open unless you have a really good reason to do so (e.g. you're fixing it yourself). If it hasn't been fixed in the last 3 years, it probably won't be fixed anytime soon either. Sorry.
