Trackpoint Config on Thinkpads

OBSD-6.8-beta X11 trackpoint/nipple

2020-10-12


Track point scrolling isn't configured out of the box, and accelaration is dead slow.

Essential pointer configs

# gas gas gas I'm gonna set on the gas
xinput set-prop 7 'Device Accel Constant Deceleration' 0.3

Enjoy Rubbing Nipple, kinky ;)

10-14 Update - Making Config Persist

I was lazy, and after reboot due to new snapshot (my shortest uptime 2 days) it backfired.

The easiest way is to make wm start xinput (blinking with fvwm, probably update to fvwm2 in ports) but to avoid furhter confusions I'm clustering all x settings in sessions file. (helpful when I change fvwm hope it's not the case)

Going /etc/X11/xenodm/Xsessions I have created ~/.xsession

/usr/X11R6/bin/xinput set-prop 7 'Device Accel Constant Deceleration' "0.3" & 
/usr/X11R6/bin/xinput set-prop 7 'WS Pointer Wheel Emulation' "1" & 
/usr/X11R6/bin/xinput set-prop 7 'WS Pointer Wheel Emulation Button' "2" & 
/usr/X11R6/bin/xinput set-prop 7 'WS Pointer Wheel Emulation Axes' "6" "7" "4" "5" &
/usr/X11R6/bin/xterm &
/usr/X11R6/bin/fvwm

Rule of thumb, the last process should be foreground so when it ends xenodm(1) promts back to login window. more on faq
