Lubuntu 17.04 LightDM Greeter panel font hard to read

[Scott Cowles Jacobs]

The Host-Name and the clock in the Lubuntu 17.04 LightDM Greeter panel are either the same color as the background, or are almost so - it is impossible to read them, but it is - barely - possible to tell that they ARE there.

I have looked in the Properties->Installed Files for the package, and discovered the file:
/etc/lightdm/lightdm-gtk-greeter.conf (and then found the apparently (originally) identical /etc/lightdm/lightdm-gtk-greeter.conf.d/30_lubuntu.conf file in my File Manager - Nemo.

The only Panel options (changeable with "sudo lightdm-gtk-greeter-settings") are "panel-position", "clock-format", and "indicators", so I assume that the font-related aspects are derived from Appearance: theme-name.

This defaults to "Lubuntu-default".

The only other option is "Lubuntu-dark-panel". This sounds promising, and I have now set it to that, but have not yet logged out or in to see if that solves the problem.

I will report back to say if it is now fixed or not.

As defaulted, it is impossible to read.

I note that the Panel Font is Ubuntu Regular - 0. I assume the 0 means "get actual font height from somewhere else"

Appearance: theme-name --- > "Lubuntu-dark-panel"
solved the issue.

For users that have not yet installed this DM (latecomers to 17.04 or
for the next version), I would suggest either changing Lubuntu-default to
be more readable, or default the theme to "-dark-panel"

I had the same problem when I installed Lubuntu Next 17.10.

I also had to install the "lightdm-gtk-greeter-settings" package, as it was not included.
(I don't know if this is true of both LXDE and LXQt versions of 17.10, or just LXQt..).

Status changed to 'Confirmed' because the bug affects multiple users.

beta 18.04 the same. White clock font on light panel

Thank you for reporting this bug to Ubuntu.

Ubuntu 17.04 (zesty) reached end-of-life on January 13, 2018.

See this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We appreciate that this bug may be old and you might not be interested in discussing it any more. But if you are then please upgrade to the latest Ubuntu version and re-test. If you then find the bug is still present in the newer Ubuntu version, please add a comment here telling us which new version it is in.

(FYI: Lubuntu hasn't used lightdm in our last six releases, so there is a great chance it no longer applies)
