[LightDM] No Keyboard Touchpad with lightdm Mate / Dell Latitude E6420

Tue Feb 23 00:48:21 UTC 2016

Hi Edouard,

LightDM itself doesn't actually control the keyboard, you should look in
the greeter you are using (lightdm-gtk-greeter) or the session (MATE) to
see why it's not logging in.

You may also want to check that the keyboard is being assigned correctly by
running "loginctl seat-status" after starting LightDM.
