I had a background such as this one:
http://linuxvillage.org/wp-content/uploads/images/sushi-i386.png
- Lightdm Webkit Greeter Themes
- Lightdm Greeter Themes Backgrounds
- Lightdm Kde Greeter Themes
- Lightdm Webkit2 Greeter Themes
showing fine in lightdm, then I wanted to use lightdm-gtk-greeter-settings to configure a custom avatar for the login. From then I could not get my background image showing anymore, the background staid desperately white.
I have removed the lightdm suite packages two or three times already, replacing the login screen by no login screen : with nodm, then reinstalling (a bit later) lightdm and it's friend's packages, and yet could not find how to narrow where the problem could be. I was looking the /etc/lightdm configuration files, and didn't find a clue. Having done a search on the 'Askubuntu' place, I found a clue about a css file, so I looked into /usr/share/themes and found a css file under the Greybird theme. Not knowing if it could affect the configuration I un-installed greybird-gtk-theme for the time being. (Vivid is a test version right? So I am testing details, among other things, while using it daily).
Hi, I reinstalled fresh the packages 'lightdm lightdm-gtk-greeter lightdm-gtk-greeter-settings', removed nodm, after reboot, the login screen is plain black as it is expected to be, and the file '/etc/lightdm/ lightdm-gtk-greeter. Conf' looks this way. Greeter-session=lightdm-slick-greeter The slick-greeter ships with a working configuration file but you can optionally run the 'Login Window'(lightdm-settings) application and customize the greeter in many ways. Install the greeter and the configuration tool: pamac install lightdm-gtk-greeter lightdm-gtk-greeter-settings. Lxdm-themes AUR provides 6 extra themes: Archlinux, ArchlinuxFull, ArchlinuxTop, Arch-Dark, Arch-Stripes, and IndustrialArch. The ArchStripes and ArchDark themes are also packaged with lxdm-git AUR (with different names to avoid file conflicts). Choice of theme is configurable in /etc/lxdm/lxdm.conf: ## the theme of greeter theme=themename.
I had reinstalled nodm last night, and once the session on, I removed it and re-installed lightdm and lightdm-gtk-greeter and the others once more: this time after logout/login, the lightdm login screen was black as originally! But when I again tried to configure my background, using lightdm-gtk-greeter-settings : it was turned to white again! (I wanted to be sure-sure-sure of the result!)
Here are the last removes done:
***
$ history | grep 'apt-get remove'
1426 sudo apt-get remove --purge lightdm-gtk-greeter-settings
1539 sudo apt-get remove --purge lightdm lightdm-gtk-greeter
1721 sudo apt-get remove --purge nodm
1757 sudo apt-get remove nodm
1934 sudo apt-get remove --purge lightdm-gtk-greeter lightdm-gtk-greeter-settings
1969 sudo apt-get remove nodm && sudo apt-get install lightdm lightdm-gtk-greeter
1987 sudo apt-get remove --purge greybird-gtk3-theme
1988 sudo apt-get remove --purge greybird-theme
1990 sudo apt-get remove --purge greybird-gtk-theme
1991 sudo apt-get remove lightdm lightdm-gtk-greeter lightdm-gtk-greeter-settings && sudo apt-get install nodm
2013 sudo apt-get remove --purge lightdm-gtk-greeter
2039 sudo apt-get remove --purge razorqt-data
2050 history | grep 'apt-get remove'
***
and also I did a research with find in all system directories where any lightdm configuration file could eventually be hiding. With the above removals, there seem to be none left:
***
$ dpkg -S lightdm
language-pack-fr-base: /usr/share/locale-langpack/fr/LC_MESSAGES/lightdm.mo
***
What would be nice, if I knew what files lightdm-gtk-greeter-settings affect, because it seemed to change some parts of the lightdm-gtk-greeter-ubuntu.conf under /etc/lightdm each time, but isn't there other files which are modified when using it?
Can I have any pointers to how find what is wrong to help solve this?
Best regards,
Mélodie
Ubuntu uses Lightdm as the display manager. Ubuntu also uses it’s default lightdm-greeter (The UI that is displayed as User Login Page) which is named unity-greeter.
Last month, I installed several DE (Desktop Environment) namely Lubuntu, LXDE, KDE, GNOME-SHELL, razor-qt and some others. As I installed those, I noticed, the default unity-greeter can’t show all the available option for choosing DE. That was really frustrating. But, Anyhow, I managed to change the default lightdm theme in KDE system settings (That was an awesome option). But for a full understanding I played with it yesterday and am writing about how to change it’s themes to suit your tasted

Lightdm Greeter Themes Backgrounds
##Changing the greeter themesGo to /usr/share/xgreeters/ directory and check what greeter themes are available there with .desktop extension. Note the name of the greeter file. Now open /etc/lightdm/lightdm.conf with root permission and under SeatDefaults section (Yes, it is not setDefaults) change or add a line greeter-session=lightdm-gtk-greeter (assuming you wanted to use gtk-greeter).
Lightdm Kde Greeter Themes
##Changing further in lightdm-gtk-greeterLightdm gtk greeter has several alternative variants. If you use gtk-greeter, you can configure theme by using this command in a terminal
