Hi When trying to reboot , I have the following message "kubuntu Please unlock dist sda5_crypt" but the keyboard is not responsive and I am stuck. If I reboot in recovery mode , it works again. It happened immediately after I install Nvidia proprietary driver OR with the latest kubuntu 16.04 upgrade. I have the sane behavior with 2 installation (kubuntu 10.04.3). A google search shows that more and more people has this unresolved problem. Any thing
This is going to be a distro issue, not a KDE issue. Please report it to the Ubuntu folks.
