Thinkpad T530 - synaptics driver for touchpad AND mouse driver for trackpoint?

[Shane Riddle]

Thanks for your response and offer of assistance, Anthony. 

I hope this isn't overkill, I thought it may be helpful to show all the logs you requested for both configurations. 

Please let me know if this is what you were expecting. And thanks again for the help!

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. BUT - 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....
