Ubuntu 13.10 with a simlpified version of #14 partially "fixes" Lenovo ThinkPad Edge E531.
Section "InputClass" Identifier "touchpad" MatchProduct "SynPS/2 Synaptics TouchPad" Driver "synaptics" # increment noise cancellation factor Option "HorizHysteresis" "50" Option "VertHysteresis" "50" EndSection The mouse behaves a bit strange, not good, but better than before. A hysteresis value above 50 makes it even worse (in another aspect) than it was before... Seems like this particular xorg-drug comes with a side- effect ;) The E531 has a clickpad (i.e. it has its physical button under the finger-sensitivt part of the touchpad). The only way to right-click is to use this pad -.- The lack of precision affects the right click context menus, without the fix above right-clicking always opened some alternative in the right-click menu, often the first. Now, it doesn't click anything most of the time, but sometimes it does hit the first one. Left-clicking is also affected, but there is the alternative of tapping for these clicks. Some walkarounds that really don't fix the problem: * Only use tapping. Only works for left-click. * Set AreaBottomEdge - cannot set for only right-click, has to take the whole bottom edge. Might work for you. * Change the theme, some have had success with adding a non-clickable border around all context menus, effectively moving the menu way off the mouse so you don't accidentally click it. I think what we really need is a ClickHysteresis, so that the mouse doesn't move when clicking the clickpad (both left and right click). Maybe we should open a new bug for this issue? I think we could have two very similar bugs in one thread here. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/1042069 Title: Jumpy Mouse Cursor using Thinkpad X230 (+X230t) Touchpad Status in “xserver-xorg-input-synaptics” package in Ubuntu: Confirmed Bug description: Really annoying bug!
