ubuntu 14.04

之前是可以的。不知升级时改了什么，现在每次 suspend 之后，不用几秒钟就会自己又亮起来，风扇也转起来。

这个怎么弄？

1.

再打开一个终端，
如出现故障，把前一个终端新产生的输出贴上来。另把 /var/log/pm-suspend.log 的内容也贴上来。

2.
此种故障，很多情况下是由USB引起的。
方法一是在 /etc/pm/config.d/ 下 配置 SUSPEND_MODULES，但只对 pm-suspend 生效，对关机重启菜单里的待机无效。
方法二是配置 /proc/acpi/wakeup。
具体操作方法因硬件而异，谷歌 ‘ubuntu suspend immediately wake up’ 有很多相关信息。

3. 网卡 / 显示驱动也可能造成此问题。具体要看第一步的信息

这是 kern.log 的输出：
