https://bugs.freedesktop.org/show_bug.cgi?id=104990 --- Comment #17 from Peter Hutterer --- It's a so-called schmitt trigger, pressure needs to go above "down" to be detected as touch and below "up" to be released again. down > up to make the touch more resilient. libinput:name:*CyPS/2 Cypress Trackpad:dmi:*svnDell:*pnXPSL322X* LIBINPUT_ATTR_PRESSURE_RANGE=105:60 LIBINPUT_ATTR_PALM_PRESSURE_THRESHOLD=230 Something like this should work. Check /sys/class/dmi/id/modalias and adjust the dmi bit accordingly, make sure the svn and pn bits match. https://wayland.freedesktop.org/libinput/doc/latest/faq.html#faq_hwdb_changes I'll need you to figure out that hwdb match though, I can't test this locally without the same machine so anything I'd merge is prone to be buggy. -- You are receiving this mail because: You are the assignee for the bug.___ wayland-bugs mailing list wayland-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/wayland-bugs

https://bugs.freedesktop.org/show_bug.cgi?id=104990 --- Comment #16 from Sean Lanigan --- I should note though that I don't really understand the full implications of the lower and upper thresholds - does "down" translate to a click? Or is "down" the minimum pressure required to actually move the cursor? If the latter, the values are much too high - I was thinking it was the former. -- You are receiving this mail because: You are the assignee for the bug.___ wayland-bugs mailing list wayland-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/wayland-bugs

This is an iterative process and I need you to play around with the touch thresholds until you come up with one that works reliably, both for finger detection and palm detection. Please see https://wayland.freedesktop.org/libinput/doc/latest/touchpad_pressure.html#touchpad_pressure_hwdb for the details. Ideally, the pressure thresholds should reliably detect touches but ignore accidental light brushes. -- You are receiving this mail because: You are the assignee for the bug.___ wayland-bugs mailing list wayland-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/wayland-bugs

https://bugs.freedesktop.org/show_bug.cgi?id=104990 --- Comment #9 from VF --- Hi. I did the test with latest 18.04 daily ubuntu with libinput10 1.10.3. After reading the post of Silvio here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1746740/comments/25 I feel I have to reword "laggy": "The sensitivity was WAY too high so the cursor could only be moved with extremely low pressure" he says, far better than I did. Usual pressure seems to lock the cursor in place after a very short movement. I'd add I didn't reach to start a rectangle selection/capture with the touchpad, what I can usually do with quick double-tap to set the 1srt corner then move the cursor to the opposite corner where I want. I'll give another try within minutes and come back here only to say I succeeded. -- You are receiving this mail because: You are the assignee for the bug.___ wayland-bugs mailing list wayland-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/wayland-bugs
