Title:
No login on the text console (tty) more possible (4.15.0-45)
Status in linux package in Ubuntu:
Incomplete
Bug description:
Dear Maintainer,
When updating the kernel from 4.15.0-43 to 4.15.0-45, a fatal error
occurs when logging in to the text console (multi-user target,
Runlevel 3). After entering the login name (eg root) plus enter key,
the cursor immediately moves on from the input prompt for the
password, i. it sent an empty password for login. This is wrong and
not correct.
The cursor moves to enter the password, but jumps immediately. The
error message "Login incorrect" appears four times. Then the erroneous
login messages are cleared on the screen and it starts all over again.
The bug also occurs with kernel 4.18.0-14, which I have installed as a
trial, affecting at least two kernel versions of it 4.15.0-45 and
4.18.0-14. The error does not occur if you want to log in as root
after starting the KDE desktop with the console. So the last working
kernel is 4.15.0-42.
The error does not occur if you want to log in as root after starting
the KDE desktop with the console. Is the error already known neon or
is there a bug report about it? What can you do that the login with
the above mentioned kernel versions in the text console works again?
Distribution: KDE neon User Edition 5.14
Kernel : 4.15.0-45-generic
# cat /proc/version_signature
Ubuntu 4.15.0-45.48-generic 4.15.18
regards
Michael
