Ubuntu 10.04 插上SD卡无法待机

                                          Ubuntu 10.04 插上SD卡无法待机

                                                    周银辉 

不习惯关机，而习惯合上笔记本盖子 让其休眠，但今天下午发现休眠不了，指示灯一直闪，貌似在告诉我它一直在“正在准备休眠中 ...”  后来，发现是我插入点SD卡在作怪，拔掉卡就可以正常休眠，不知道深层次点原因是什么，但我们可以通过在在休眠前unmount 掉SD卡来解决这个问题

找到/usr/sbin/pm-suspend这个符号链接，用文本编辑器打开它，加入如下代码：

umount /media/yourSdCardName

其中yourSdCardName是你SD卡被mount上时的名称

下面是我的pm-suspend文件，仅供参考，我仅仅添加了umount /media/EOS_DIGITAL这句代码以及其注释，其他是系统自带的
