ubuntu系統一個流行的linux操作系統，眾所周知，在ubuntu 9.10中換了新版本的gdm，所以不再像之前那樣簡單的更換登錄界面。下文就教大家讓ubuntu 9.10系統更換登錄界面的方法

最終，只是在這里：http://ubuntuforums.org/showpost.php?p=7576112&postcount=365 找到了更換方法，但仍有些東西不能生效，但總比之前找到那些靠譜

具體方法參考上面連接，這里copy過來作為備忘錄，免得以后連接 404 ……

1. Change the gdm background picture

The current settings

sudo -u gdm gconftool-2 –get /desktop/gnome/background/picture_filename

Set a new background picture

sudo -u gdm gconftool-2 –set –type string –set /desktop/gnome/background/picture_filename /data/pictures/Grassy.jpg

2. The gdm gtk theme

The current settings

sudo -u gdm gconftool-2 –get  /desktop/gnome/interface/gtk_theme

Set a new gtk theme (you can find them in /usr/share/themes)

sudo -u gdm gconftool-2 –set –type string –set /desktop/gnome/interface/gtk_theme Redmond

3. The gdm icon theme (changes the look of the computer icon … icon above the hostname)

The current settings

sudo -u gdm gconftool-2 –get /desktop/gnome/interface/icon_theme

Set a new icon theme (You can find them in /usr/share/icons)

sudo -u gdm gconftool-2 –set –type string –set /desktop/gnome/interface/icon_theme Tangerine

and you can edit the file

/usr/share/gconf/schemas/gdm-simple-greeter.schemas

if you don’t like the computer icon. Change the icon (<default>coputer</default>) in the section

<schema> 
 
<key>/schemas/apps/gdm/simple-greeter/logo_icon_name</key> 
 
<applyto>/apps/gdm/simple-greeter/logo_icon_name</applyto> 
 
<owner>gdm-simple-greeter</owner> 
 
<type>string</type> 
 
<default>computer</default> 
 
<gettext_domain>gdm</gettext_domain> 
 
<locale name=”C”> 
 
<short>Icon name to use for greeter logo</short> 
 
<long>Set to the themed icon name to use for the greeter logo.</long> 
 
</locale> 
 
</schema> 

4. The gdm user icon

This does not work

sudo -u gdm gconftool-2 –get /schemas/apps/gdm/simple-greeter/logo_icon_name

I haven’t found it yet … but at least we could overwrite

/usr/share/icons/gnome/scalable/stock/generic/stock_person.svg

but this icon may be important for other applications … so don’t do it.

solved: you can set the user icon for your user with

/usr/bin/gnome-about-me
