I have following config:

DVI-I-1 connected 2560x1440+0+0 (normal left inverted right x axis y axis)
597mm x 336mm
   2560x1440     59.95*+
 (skip)
HDMI-0 connected 1920x1080+2560+0 (normal left inverted right x axis y axis)
293mm x 165mm
   1920x1080     60.00*+
(skip)

If I trying to map keyboard via xinput it crashes X server:

xinput --create-master second
xinput --map-to-output 'second keyboard' HDMI-0

I understand that 'map-to-output' for keyboard is stupid, but server crash is
not good too.
