Comment # 2 on bug 915661 from Freek de Kruijf

> Freek, can you reproduce this 'slowness' with another WM?

On the login screen I choose Plasma5 instead of KDE, I don't know if that is
what you asked, but it made no difference. When starting a console, I am unable
to enter characters through the keyboard. So something is really messed up.
