** Description changed: The mx4 touch screen sends a BTN_TOOL_FINGER key event during the touch down and up.. This interferes with position tracking inside libinput and leads to invalid positions being reported and in some cases jumping of the position just before the release of a touch contact. There is a fix posted at the libinput mailinglist, but those have not been applied yet. (Peter is on vacation). Latest update of the touch screen patches (these will compensate the initial jumping of touch contacts , but not fix the mx4 issue) - http://lists.freedesktop.org/archives/wayland-devel/2015-September/024168.html + http://lists.freedesktop.org/archives/wayland-devel/2015-November/025159.html The last step, the actual mx4 fix: http://lists.freedesktop.org/archives/wayland-devel/2015-September/024171.html + + Editor node: ^ Updated the patches for the most current version v8 on + top of 1.1.0 of libinput.
