It seems that the clickpad dimensions are reported incorrectly so the percentage-based configuration does not work correctly. My Xorg.0.log reports: [ 14.664] (--) synaptics: SynPS/2 Synaptics TouchPad: x-axis range 1472 - 5112 (res 42) [ 14.664] (--) synaptics: SynPS/2 Synaptics TouchPad: y-axis range 1408 - 3834 (res 42) But using evtest I empirically determined different dimensions, which are present in my current config: 1 Section "InputClass" 2 Identifier "T440p touchpad w/o cursor movement" 3 MatchDriver "synaptics" 4 Option "SoftButtonAreas" "3800 0 0 2500 2600 3800 0 2500" 5 Option "TouchPadOff" "1" 6 Option "AreaBottomEdge" "1" 7 8 Option "LeftEdge" "1024" 9 Option "RightEdge" "5110" 10 Option "TopEdge" "2048" 11 Option "BottomEdge" "5000" 12 EndSection I remember having read something about incorrect dimension reports by the Linux kernel, but I am currently running 3.17-rc2 and would have expected this to be fixed already in that release. How can I further help debugging this issue? Thanks, Thilo
