Often we find a better solution down the road once hardware improves but then cannot easily remove it because users rely on the previous configuration. I pushed a branch for pressure-based palm detection yesterday, see <a class="bz_bug_link bz_status_NEEDINFO " title="NEEDINFO - Palm detection: ignore moves over a pressure threshold" href="show_bug.cgi?id=94236">Bug 94236</a>. I suggest given that a try first because it may help with a bunch of issues like the 25% change you need atm. (In reply to Ming-Yang Lu from <a href="show_bug.cgi?id=101574#c3">comment #3</a>) > Also, libinput doesn't consider trackpoint button events as > trackpoint usage if I'm right, the palm detection didn't works well > sometimes while double-clicking. true, it's intended. we have a lot of users that use the touchpad for movement but the trackpoint buttons for clicking - disabling the touchpad is not useful in that case. I guess one of the possibilities could also be to increase the trackpoint timeout on demand when true trackpoint usage is detected. e.g. more than X events from the trackpoint -> timeout is now 1s instead of the few ms we have now. I'm not sure that would help in your case though, I think a 5% edge may still be the best option.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
