Can someone of lubuntu users compare content of /etc/lightdm/ in 15.04 and 15.10?

Lyn Perrine (walterorlin) wrote :

lightdm-gtk-greeter.conf from wily which seems to have all settings for the greeter commented out and not applied.

Lyn Perrine (walterorlin) wrote :

This is the lightdm conf from vivid of lightdm-gtk-greeter.conf which is a simlink to the -ubuntu version with a users version.

users.conf on both greeters appears to be the same.

So, something has changed in the way lightdm-gtk-greeter is packaged and works. The work around is to do the following:

sudo cp /etc/lightdm/lightdm-gtk-greeter-ubuntu-mate.conf /etc/lightdm/lightdm-gtk-greeter-ubuntu-mate.conf.d/50_ubuntu-mate.conf

summary: - lightdm boots to black background at greeter for latest lubuntu
+ lightdm has black greeter background for Lubuntu and Ubuntu MATE 15.10

Fix released for Ubuntu MATE 15.10 Alpha 1.

summary: - lightdm has black greeter background for Lubuntu and Ubuntu MATE 15.10
+ lightdm has black greeter background for Lubuntu

I can confirm this fixed in Lubuntu i386 Alpha 1.

I would seem to think it would be fair to render the bug against lightdm-gtk-greeter Invalid since the change in its packaging doesn't necessarily seem to be a bug. If someone feels otherwise, I suggest opening a new bug.
