Maybe the subject is too trivial to make a post out of it but actually I could not find much information on how to fully customize the login screen.
There is a lot of literature about customizing the login icons but nothing much about the rest.
So hopefully the next few lines will be helpful to some of you...

The following picture shows a login window with a custom background and colors.
It also shows the nixieclock program started on the bottom right.



At first:
I just discovered Erco's nixieclock today. If you want to try, you can download it from there:
http://seriss.com/people/erco/unixtools/nixieclock/

1. How to customize background and programs started at login screen:
The following is a compilation of various pages I found in https://wiki.preterhuman.net to make it work

a. Install neko_xli

b. Create files Xsetup and Xsetup-remote in folder /usr/lib/X11/xdm/
chmod 777 both files

c. Edit Xsetup file:
Add the following lines:

Code:

#custom background image
/usr/nekoware/bin/xli -onroot /path/to/wallpaper/login_pix.jpg
#nixieclock
/path/to/nixieclock/nixieclock
#don t forget that one
exit 0

Note: if you are adventurous enough, you can try to include other programs (Quake3??)

d. Edit Xsetup-remote file and add the same lines

e. Edit /var/X11/Xdm/xdm-config
- Set DisplayManager*grabServer to False
- Add the following 9 lines:


2. Change the login window colors:
If you are using a custom color scheme, you can change login window colors by editing the base color scheme located here:
/usr/lib/X11/schemes/Base/BaseColorPalette
Note: I wasn't able to change the login window background color...

You are done!

Not at all I like posts like this

Just FYI the login window BG color is controlled through the Theme color CP.
As I recall that address also controls some in-session colors so approach with caution.
