如何获得Ubuntu 12.04识别加密的交换分区以便休眠？

我刚刚安装了Ubuntu 12.04，并使用gparted擦除和扩大了我的交换分区。重新启动后，gparted表示交换的文件分区是未知的。Gparted不允许我将文件分区更改为“ linux-swap”。它的确使我将其更改为NTFS，但是当我重新启动时，它又回到了“未知”状态。在此先感谢您的帮助。

Disk /dev/mapper/cryptswap1 doesn't contain a valid partition table

由于“ cryptswap1”，您似乎正在使用加密交换。挂起时会生成一个随机访问密钥，以便在恢复时访问加密的交换。有时，该随机密钥在系统中丢失。我建议您创建一个密码，您需要在恢复时手动输入该密码。这将逐步向您展示如何创建加密的交换分区并设置其密码。
