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

Hi,

My system is a KDE Neon system and here the package "apport" is not installed. Can I attach the required log files manually here to the bug report. Which files are that?

Thanks!

I can confirm this bug. Any way to run "apport-collect" from a remote (ssh,VNC,x2go) connection?

runnign 'sudo apport-collect 1814439' over SSH gives me this error message:

And running it as a 'apport-collect 1814439' gives me this:
