Public bug reported:
Description: Ubuntu 16.04.1 LTS
Release: 16.04
Package version: 16.04.2-0ubuntu1
Is it possible to either dynamically expand the width and height of
the greeter box in order to fully display PAM messages? If one uses
Kerberos for authentication, the Unity greeter truncates/fades out the
full text returned by PAM concerning Kerberos password/principal expiry:
The attached unity-greeter-truncations.tar file contains three PNG files
illustrating truncation when:
- a password is about to expire.
['password_expire_soon.png']
- you enter the previous password in the 'change password' dialog and
local policy prevents re-use.
['expired_same_password.png']
- you enter a password that does not meet local policy requirements
in the 'change password' dialog.
['password_change_rejected.png']
The truncation can make it difficult for end-users to understand
what is going on. Other display managers - such as gdm and mdm -
are able to display such text in full.
In the ubuntu-greeter source src/greeter-list.vala, it is possible to
increase the default width of the greeter box by increasing the value below:
public static const int BOX_WIDTH = 8;
This is not a great solution because the login box is aesthetically
unpleasant when it is that wide at all times. Furthermore, the
PAM text displayed by unity-greeter is not line-wrapped, making
the choice of a suitable value for BOX_WIDTH impractical.
unity-greeter clearly has support for dynamically adjusting the height
of the greeter box. Would it be possible, therefore, to add support
for dynamically adjusting the width and to format displayed PAM text
so that it is at most, say, seventy-five characters long?
