[root@localhost ~]# mouse-dpi-tool /dev/input/event7
Mouse Microsoft Microsoft® 2.4GHz Transceiver V1.0 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: 9837 at frequency 142.9Hz | /^C
Estimated sampling frequency: 142Hz
To calculate resolution, measure physical distance covered
and look up the matching resolution in the table below
624mm 24.59in 400dpi
416mm 16.39in 600dpi
312mm 12.30in 800dpi
249mm 9.84in 1000dpi
208mm 8.20in 1200dpi
178mm 7.03in 1400dpi
156mm 6.15in 1600dpi
138mm 5.46in 1800dpi
124mm 4.92in 2000dpi
113mm 4.47in 2200dpi
104mm 4.10in 2400dpi
If your resolution is not in the list, calculate it with:
resolution=9837/inches, or
resolution=9837 * 25.4/mm
Entry for hwdb match (replace XXX with the resolution in DPI):
mouse:usb:v045ep071d:name:Microsoft Microsoft® 2.4GHz Transceiver V1.0:
MOUSE_DPI=XXX@142
[root@localhost ~]# cat /usr/lib/udev/hwdb.d/71-mouse-local.hwdb
mouse:usb:v045ep071d:name:Microsoft Microsoft® 2.4GHz Transceiver V1.0:
MOUSE_DPI=1000@142
[root@localhost ~]#
But no MOUSE_DPI shows up:
udevadm info /dev/input/event7 | grep MOUSE_DPI
[root@localhost ~]# udevadm info /dev/input/event7
