Ubuntu 17.04 冻结问题

否则，稳定的 Ubuntu 机器在安装后会出现问题，即无明显原因地严重冻结。该问题很可能是由 NVDIA 显卡引起的。

sudo blkid输出：

/dev/sda2: UUID="0E5C95E45C95C73D" TYPE="ntfs" PARTUUID="1ef0523b-02"
/dev/sda5: UUID="16EA-1372" TYPE="vfat" PARTUUID="1ef0523b-05"

/etc/fstab：

# /etc/fstab: static file system information.

# Use 'blkid' to print the universally unique identifier for a

17.04 和加密交换文件似乎存在问题......并且有一些解决方法......

像这样编辑/etc/crypttab：

gksudo gedit /etc/crypttab

更改此行：

cryptswap1 UUID=xxxx-xxxx-xxxx-xxxx /dev/urandom swap,offset=1024,cipher=aes-xts-plain64

对此：

cryptswap1 /swapfile /dev/urandom swap,offset=1024,cipher=aes-xts-plain64

还要确保您的文件/etc/fstab包含以下内容：

/swapfile               none  swap  sw  0  0
/dev/mapper/cryptswap1  none  swap  sw  0  0
