Ubuntu 17.04冻结问题

否则稳定的Ubuntu机器有一个问题,因为安装是严重冻结没有明显的原因。 该问题很可能是由NVDIA显卡引起的。

  • 崩溃时syslog的例子

sudo blkid输出:

 /dev/sda2: UUID="0E5C95E45C95C73D" TYPE="ntfs" PARTUUID="1ef0523b-02" /dev/sda5: UUID="16EA-1372" TYPE="vfat" PARTUUID="1ef0523b-05" /dev/sda6: UUID="fe90c52c-c1b7-4845-971e-e7ed5cb45ac4" TYPE="ext4" PARTUUID="1ef0523b-06" 

/etc/fstab

 # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # #       # / was on /dev/sda6 during installation UUID=fe90c52c-c1b7-4845-971e-e7ed5cb45ac4 / ext4 errors=remount-ro 0 1 /swapfile none swap sw 0 0 /dev/mapper/cryptswap1 none swap sw 0 0 

/etc/crypttab

 cryptswap1 UUID=f09a516a-22c0-475c-b749-31ffed5c7bda /dev/urandom swap,offset=1024,cipher=aes-xts-plain64 

ls -alh /swapfile

 -rw------- 1 root root 2.0G May 3 13:31 /swapfile 

17.04和加密交换文件似乎存在问题…并且有一些解决方法……

像这样编辑你的/etc/crypttab

 gksudo gedit /etc/crypttab 

改变这一行:

 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/etc/fstab包含以下内容:

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