I am using FreeBSD 10.3 RELEASE on a Thinkpad T530. I'm trying to get both the Trackpoint and Touchpad into (my definition of) a fully functional state. Since "a fully functional state" is a completely subjective term, here's how I'm defining it for each device. * Trackpoint: Trackpoint 'nub' works for mouse pointer movement, and all three buttons working. * Touchpad: two-finger scrolling, tap-to-click I will try to describe the trial & error methods I have used as clearly as possible.... In all cases, the following is true. ----------------------------------- Installed Ports ----------------------------------- * x11/libsynaptics * x11-drivers/xf86-input-synaptics ----------------------------------- /boot/loader.conf ----------------------------------- hw.psm.synaptics_support=1 hw.psm.trackpoint_support=1 ----------------------------------- /usr/local/etc/X11/xorg.conf ----------------------------------- Section "ServerLayout" Identifier "X.org Configured" Screen 0 "Screen0" 0 0 InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" Option "AutoAddDevices" "false" EndSection Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/sysmouse" Option "ZAxisMapping" "4 5 6 7" EndSection The first change I made was to /etc/rc.conf. ------------- /etc/rc.conf ------------- moused_enable="YES" moused_flags="-V -a 1.6 -U 4 -L 1.5" In this state, my trackpoint is "fully functional" and my touchpad has "limited functionality" due to the fact that I can't get two-finger scrolling to work. I can use vertical-edge scrolling with one finger; however after much effort to do so, I just can't get comfortable with this. Looking at output from sysctl seems ok, except for one thing: hw.psm.synaptics.two_finger_scroll: 0 And if I change this value to "1" then vertical edge scrolling stops working, while two finger scroll *still* doesn't work. This leads me to conclude that despite a change recently introduced (1), my particular touchpad hardware is not supported through the mouse driver. (1) https://lists.freebsd.org/pipermail/freebsd-current/2015-April/055381.html Then, I tried to use the synaptics driver in xorg.conf. ----------------------------------- /usr/local/etc/X11/xorg.conf ----------------------------------- Section "InputDevice" Identifier "Touchpad0" Driver "synaptics" Option "Protocol" "psm" Option "Device" "/dev/psm0" Option "EmulateTwoFingerMinZ" "7" Option "EmulateTwoFingerMinW" "7" Option "VertScrollDelta" "-111" Option "VertTwoFingerScroll" "on" Option "VertEdgeScroll" "off" EndSection This only works if I disable moused. -------------------- /etc/rc.conf -------------------- moused_enable="NO" Otherwise, the synaptics driver can't use /dev/psm0. I guess the mouse driver selects /dev/psm0, blocking its use by the touchpad. After diabling moused, the touchpad works *perfectly* but unfortunately, the Trackpoint now doesn't work at all. No buttons, no nub movement. BUT - a USB mouse still works fine, which uses the mouse driver. Hopefully I've described this somewhat coherently. :) Has anyone ever encountered a situation like this? Any known solutions, or additional debugging steps?help
