ubuntu 9.10改换登录界面的办法[Linux安全]

　　众所周知,在ubuntu 9.10中还了新版本的gdm,所以不再像之前那样简单的改换登录界面

　　在网上搜到几种办法,不知道是我的机械情形特别还是说他们转来转去根本就不靠谱,反正我是没改成,后果还弄的不人不鬼

　　终究,只是在这里:http://ubuntuforums.org/showpost.php?p=7576112&postcount=365 找到了改换办法,但仍有些东西不能见效,但总比之前找到那些靠谱

　　具体办法参考上面衔接,这里copy过来作为备忘录,免得今后衔接 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
