Idea #17390: Login screen color meshes badly with non-brown wallpaper

Written by firexq the 17 Jan 09 at 06:51. Related project: Gnome. Status: New
Rationale
When users change their wallpaper to a non-brown one, the screen color while it loads during login remains tan; this can look really, really bad. One logs in; a tan color displays; then a violent blue picture replaces it.

The availing solution is manually changing the default login-background (not the normal background) at /etc/gdm/PreSession/Default. If the user does not know where this is or how to edit it, the visual flaw remains.

Solution #1: Automatically assess wallpaper, change default
Written by firexq the 17 Jan 09 at 06:51.
When the user imports a new wallpaper to Appearance Preferences, Ubuntu should quickly analyse it average color. When the user chooses the wallpaper and later logs in, that color should display while the wallpaper is loading.

Solution #2: Fade into the desktop gradually

Make a smooth transaction from login page directly to background, without any intermediate same-colour background.

Solution #3: Preserve GDM wallpaper until Nautilus sets its own
Written by nightjarrr the 17 Jan 09 at 22:51.
I've found this wonderful solution in Launchpad. A small fix makes the GDM theme wallpaper remain visible until Nautilus takes over the desktop and displays its wallpaper. No intermediate color changes! Just one-moment change from one wallpaper to the other.

Kudos go to the author, Kristoffer Grönlund (https://launchpad.net/~kegie)

The fix proposal:
https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/278017

The fix is really simple. Two notes on it:
1. The gdm script is /etc/gdm/PreSession/Default on my system
2. GDM themes are located in /usr/share/gdm/themes.

Solution #5: Background changes to selected (blurred) user's background...
Written by Tom Mann the 19 Jan 09 at 16:19.
As a sexiness thing, I think when you enter your username and get to the password bit, the background should become a blurred version of the user's wallpaper (like looking through frosted glass). When the password is entered and log in occurs it should 'unfrost'. That would be tasty.

Solution #7: load the user's wallpaper (optionally)
Written by yzarc the 7 Feb 09 at 23:21.
after the user login was typed or select by face selector, fade-in the wallpaper of this user onto the background of the GDM while he type his password. make it as optionally for each user due privacy issues.

GNU/Linux is a multiuser operating system.

Maybe the colour should reflect the gdm/kdm theme colours rather than the individual users colours?

Mine isn't multi-user and i'm keeping it that way. Sometimes i let people watch the screen or show it off but they can get their own Ubuntu ;)

Your Ubuntu has at least 2 users: you and root :)

@glotz GNU/Linux is just what Ubuntu uses to run GNOME.
