在Fedora15的使用过程中，偶尔会不小心点击“挂起”选项。结果便是黑屏，重启也无法恢复。只有断电一段时间之后才能恢复。所以，禁用挂起功能是有必要的。（节选自https://bbs.archlinux.org/viewtopic.php?pid=944867#p944867）
（将*替换为登录用户名即可）
将绿色文字内容复制保存，名为50-admin.pkla，放到/etc/polkit-1/localauthority/50-local.d目录下。
I got this from somewhere else on the internet, but I'm not sure where anymore. In any case, it works.
To disable suspend and hibernation, add a file named 50-admin.pkla to:
/etc/polkit-1/localauthority/50-local.d
full path as reference:/etc/polkit-1/localauthority/50-local.d/50-admin.pkla
Add the following text to the file and save it. Log out and back in. This will remove suspend and hibernate from the shut down menus
[color=Lime][disable suspend]
Identity=unix-user:*
Action=org.freedesktop.upower.suspend
ResultAny=no
ResultInactive=no
ResultActive=no
[disable hibernate]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultAny=no
ResultInactive=no
ResultActive=no
[/color]
注销之后重新登录，如图：
