I guess the mouse = driver selects /dev/psm0, blocking its use by the touchpad.=20 Right, I believe xf86-input-synaptics only works with psm(4). > After diabling moused, the touchpad works *perfectly* but unfortunately= , the Trackpoint now doesn't work at all. No buttons, no nub movement. BU= T - a USB mouse still works fine, which uses the mouse driver. Sounds like moused(8) drives the Trackpoint, if it quit working after disabling moused. What are the outputs of the following commands: 1) dmesg | grep psm 2) grep -C 5 -i '\(ps/2\|synaptics\)' /var/log/Xorg.0.log # in the "touchpad working perfectly" configuration 3) ps axww | grep -v grep | grep moused # in the "trackpoint working perfectly" configuration It might be useful to see /all/ of /var/log/Xorg.0.log, not just the Synaptics and PS/2 lines.... --=20 Anthony Jenkins
