Description Tomasz Olszak 2016-11-23 11:06:02 UTC 
If you have locale that prints real numbers with commas e.g. 1,25 or 1,50 regular udev rule with LIBINPUT_CALIBRATION_MATRIX won't work. The problem is sscanf in udev_seat expects string with number to correcponding LC_NUMERIC locale. It would be nice if we could use 1.25 in settings and not be dependent on locale.
Comment 1 Tomasz Olszak 2016-11-23 11:06:42 UTC 
You can check it with locale:
LC_NUMERIC=pl_PL.UTF-8
