    TPPS/2 Elan TrackPoint   id=12
-Note id=12 (may be different on your laptop).
+Then, use the above string identifier:
-   $ xinput --list-props 12
+   $ xinput --list-props 'TPPS/2 Elan TrackPoint'
    ...
    libinput Accel Speed (300):     0.000000
    libinput Accel Speed Default (301):     0.000000
    ...
 Experiment with the Speed setting; negative values allowed. For example,
-  $ xinput --set-prop 12 'libinput Accel Speed' -0.25
+  $ xinput --set-prop 'TPPS/2 Elan TrackPoint' 'libinput Accel Speed' -0.25
+(Instead of the string 'TPPS/2 Elan TrackPoint', you can use the id number '12', but this value may vary if you have an external keyboard or mouse plugged in at login time.)
-Once you're satisfied, add the command as a startup application (typically under Start menu > Preferences > Startup). Note that the id numbering may change if you have an external mouse plugged in at login time. The following command is more reliable:
-  xinput --set-prop $( xinput | perl -ne '/TrackPoint.*id=(\d+)/ && print $1;' ) 'libinput Accel Speed' -0.25
