    8G内存，设置了12G的SWAPfile，怎么不够呢？

    按ctrl + alt + esc打开系统监视器看看交换分区用上了没？

    控制中心里电源管理貌似有点小问题，不久前我设关闭显示器、电脑进入待机模式和自动锁屏都是30分钟，结果5分钟就息屏了，不知道现在怎么样了。

    P.S. 测试可以休眠，但是再开机只能进桌面看到之前的窗口进程，系统实际卡死，过了一会儿自动重启了。感觉没啥用，缓解没有休眠按钮的强迫症 XD

    joy 我这里遇到一样的问题，之前手贱换了 btrfs 文件系统，设置了 swapfile 之后还是没有休眠按钮。

    今天查了下谷歌找到原因了：grub 启动参数缺少 resume 和 resume_offset，休眠的时候找不到 swap header
    https://bbs.archlinux.org/viewtopic.php?id=211144

    1. 执行 systemctl hibernate，和你结果一样 Failed to hibernate system via logind: Not enough swap space for hibernation

    2. 以 root 身份执行 echo disk > /sys/power/state 看看能不能休眠，我这里休眠后自动唤醒了。执行 sudo tail -100f /var/log/kern.log 查看内核日志，发现错误 PM: Swap header not found!

    3. 根据 ArchLinux 论坛的帖子，以 root 身份执行 filefrag -v /swapfile绝对路径 | awk '{if($1=="0:"){print $4}}' 获取到 swapfile 的偏移量；执行 blkid 获取根目录分区的 UUID

    4. 修改 /etc/default/grub，在 $GRUB_CMDLINE_LINUX_DEFAULT 中添加以下内容：

      resume=UUID=上面获取的根目录分区UUID resume_offset=上面获取的swapfile偏移量

    5. 执行 sudo update-grub 更新 grub 启动菜单，重启之后我这里就能显示休眠按钮了
