As a user, I have learned how to rotate in "man evdev", and in "man > wacom", I expected to learn how to rotate in "man libinput"; I filled a bug > when I didn't find the info! redundancy also means that there's at least one more space where the documentation is likely out of date :) no problem pointing to the authoritative source from libinput, etc. but imo there should only be one real documentation. > By the way, out of curiosity, I looked in libinput source at the > explanations in function evdev_device_calibrate.

The libinput matrix is relative to the device range, the X server one is relative to the screen size. you can use the x server one to map a device to one of two monitors, you can use the libinput one only for e.g. turning a device upside-down. generally, the libinput matrix is supposed to undo hw oddities, not for screen mapping (because libinput doesn't have screen mappings). http://wayland.freedesktop.org/libinput/doc/latest/absolute_axes.html -- You are receiving this mail because: You are the assignee for the bug.
