谁能给个/etc/sudoers文件呀，贴出来也行亚   

(已解决)

估计楼主是希望在执行一些管理命令时不需要 su 切换吧？
我自己的改了一下，普通用户可以使用 sudo 命令且不需要密码提示：
另外，需要编辑 /etc/group 文件，把你的普通用户添加到 wheel 组里面，比如 wheel:x:10:lovefruit
----------------
# Uncomment to allow people in group wheel to run all commands
%wheel        ALL=(ALL) ALL

# Same thing without a password
%wheel        ALL=(ALL) NOPASSWD: ALL

我用普通帐号sudo 出现这个Gtk-WARNING **: cannot open display:


艾，到网上找两个下，结果没备份sudo崩了
