Much faster because you can then run sudo ./builddir/libinput-debug-gui straight from the repo (no need to install) and check if the jitter is still present. That cursor movement is controlled by libinput directly (hitting esc quits). If you find the right value(s), then you can push them to the property and check again. It may even be that you need different values for x and y.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
