Given a libinput recording, print the timestamps of any finger changes, i.e. which slots are currently logically down. For example: Timestamp | Rel time | Slots | -------------------------------------- 0.000000 | +0.000s | + | | | | 0.454631 | +0.454s | | | | | 5.065401 | +4.610s | + | | | | 6.140281 | +1.074s | + | + | | | 7.410377 | +1.270s | | + | | | 7.420200 | +0.009s | | | | | 11.233108 | +3.812s | + | + | | | 11.850206 | +0.617s | | | | | 13.827740 | +1.977s | + | | | | 14.704027 | +0.876s | + | + | | | 16.050577 | +1.346s | + | | | | 16.905186 | +0.854s | | | | | This data is available with the per-slot-delta tool but the output here is more compressed, making it easier to detect stuck fingers. Pressure thresholds are not currently supported. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

Use the single-touch BTN_TOOL_ bits instead of the slot state. The output
|
|
will only show the "highest" finger down at any time. For examples, where
|
|
two fingers are down, only the second slot will be marked as down.
|
|
.SH OUTPUT
