in kubuntu 17.04, this last times shift key is not working: only in kubuntu, not in pclinuxos nor in wondows 10, only as duns user not as other user.
so the problem is something in user configuration.
Where are stored keyboard settings, or other settings which could interfere, in kde 5, i.p. kubuntu?
i tried delete home/.kde, but nothing to do.
curious: in clementine also in duns user shift key works normally.
Many thanks
