I am using LightDM on my work laptop (under Ubuntu 18, to log in to Cinnamon). We use LDAP (well, Active Directory) for authentication; when i am in the office, my password is checked against the server, and the result is somehow cached, so that when i am not in the office, i can still log in.
When i log in using these cached credentials, the greeter presents a message telling me that this has happened, and how long i have until the credentials expire.
However, the greeter is not actually big enough to display this message:
And so i have no idea how long i have left.
Is there a way to make the greeter box considerably wider?
EDIT here is my LightDM greeter configuration:
$ lightdm --show-config 2>&1 | grep greeter C greeter-wrapper=/usr/lib/lightdm/lightdm-greeter-session F greeter-session=unity-greeter C /usr/share/lightdm/lightdm.conf.d/50-greeter-wrapper.conf F /usr/share/lightdm/lightdm.conf.d/50-unity-greeter.conf
