1. 命令行如下：

xsj1987@ubuntu:~$ ls -l /etc/gdm/gdm.schemas -rw-r--r-- 1 root root 3157 2010-04-14 16:50 /etc/gdm/gdm.schemasxsj1987@ubuntu:~$ sudo gedit /etc/gdm/gdm.schemas [sudo] password for xsj1987: xsj1987@ubuntu:~$

2. 查找文件内容如下：

    <schema>      <key>greeter/Include</key>      <signature>s</signature>      <default></default>    </schema>    <schema>      <key>greeter/Exclude</key>      <signature>s</signature>      <default>bin,root,daemon,adm,lp,sync,shutdown,halt,mail,news,uucp,operator,nobody,nobody4,noaccess,postgres,pvm,rpm,nfsnobody,pcap</default>    </schema>

3. 删除后面的root，添加到前面的default标签中

    <schema>      <key>greeter/Include</key>      <signature>s</signature>      <default>root</default>    </schema>    <schema>      <key>greeter/Exclude</key>      <signature>s</signature>      <default>bin,daemon,adm,lp,sync,shutdown,halt,mail,news,uucp,operator,nobody,nobody4,noaccess,postgres,pvm,rpm,nfsnobody,pcap</default>    </schema>
