Title:
Can not enter password to decrypt disk at boot
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I have upgraded from Ubuntu 14.04 to 14.10. My whole disk is encrypted
with luks and since the upgrade I have found I can no longer unlock my
disk at boot. The enter password screen appears, but typing does not
cause any characters to appear in the password box. However, if I hit
ctrl-alt f7 (not sure of the precise function key) I get a black
screen with a flashing white cursor and I can see the password that I
entered. This would seem to imply that this is not a problem with the
usb drivers, as has been reported in other similar bugs. It's as if
the focus is simply in the wrong place at the time when I need to
enter my password. Entering the password anyway and pressing enter has
no effect.
By using Grub to select the previous kernel, I can then decrypt my
disk and use the system as normal. The working kernel version is
3.13.0-39-generic. The problematic kernel is 3.16.0-24-generic.
