            Bug ID: 99523
           Summary: mouse-dpi-tool reports 0 dpi
           Product: libevdev
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Core
          Assignee: peter.hutterer@who-t.net
          Reporter: guillaume.horel@gmail.com

I'm trying to record the dpi for my touchpad since it seems quite slow. However
it can't seem to compute any distance as I move my finger. This is the output
from mouse-dpi-tool. It seems to record the frequency fine, but doesn't read
any distance:

sudo ./mouse-dpi-tool /dev/input/event7
Mouse FocalTechPS/2 FocalTech Touchpad on /dev/input/event7
Move the device 250mm/10in or more along the x-axis.
Pause 3 seconds before movement to reset, Ctrl+C to exit.
Covered distance in device units:        0 at frequency 70.4Hz  /^C
Estimated sampling frequency: 70Hz (mean 62Hz)
To calculate resolution, measure physical distance covered
and look up the matching resolution in the table below
       0mm          0.00in           400dpi
       0mm          0.00in           600dpi
       0mm          0.00in           800dpi
       0mm          0.00in          1000dpi
       0mm          0.00in          1200dpi
       0mm          0.00in          1400dpi
       0mm          0.00in          1600dpi
       0mm          0.00in          1800dpi
       0mm          0.00in          2000dpi
       0mm          0.00in          2200dpi
       0mm          0.00in          2400dpi
If your resolution is not in the list, calculate it with:
        resolution=0/inches, or
        resolution=0 * 25.4/mm

Output from udevadm info:

P: /devices/platform/i8042/serio4/input/input12/event7
N: input/event7
E: DEVNAME=/dev/input/event7
E: DEVPATH=/devices/platform/i8042/serio4/input/input12/event7
E: ID_BUS=i8042
E: ID_INPUT=1
E: ID_INPUT_TOUCHPAD=1
E: ID_INPUT_TOUCHPAD_INTEGRATION=internal
E: LIBINPUT_DEVICE_GROUP=11/2/12/0:isa0060/serio4
E: MAJOR=13
E: MINOR=71
E: SUBSYSTEM=input
E: USEC_INITIALIZED=2131871
Entry for hwdb match (replace XXX with the resolution in DPI):
mouse:unknown bus type:v0002p0012:name:FocalTechPS/2 FocalTech Touchpad:
 MOUSE_DPI=XXX@70

This is a FocalTech Touchpad on an Asus UX303UB latpop.

--- Comment #1 from Peter Hutterer <peter.hutterer@who-t.net> ---
the dpi bits are only meaningful for touchpads, not for mice, so this output is
expected. Use the touchpad-edge-detector instead, that should tell you if the
resolution or axis ranges are out.
