Reverting the system to gdm 2.20.10-0ubuntu5 solves the problem, so may be there's some problem with xorg on the last release, but definitively there is something wrong on 2.26.1 that breaks, at least, my installation.
I think this bug has to be assigned to gdm team. Please ask for any test you want me to do.
