我安装了全新的 Ubuntu 17.10，关机需要很长时间。大约 10 分钟。
我的电脑：
- 宏碁 Aspire E 15 E5-575G-55F8
- 中央处理器：Intel Core i5-7200U
- 显卡：Nvidia GeForce 940MX
- 内存：8GB
- 硬盘：128 GB SSD
有什么建议么？

在我将图形驱动程序更改为 Nvidia 之后，我能够从关机中获得更多输出： 网络和 WPA 请求者关闭耗时 5 分钟

编辑 gparted：
答案1
我的猜测是它与 WiFi 有关。尝试在关机前关闭 WiFi，看看效果如何。
答案2
由于某种原因，您的加密/swapfile设置不正确，因此您根本没有使用交换。
主要问题似乎出在您的/etc/crypttab文件中。
使用以下方式编辑此文件...
sudo -H gedit /etc/crypttab
改变这个：
cryptswap1 /target/swapfile /dev/urandom swap,offset=1024,cipher=aes-xts-plain64
更改为：
cryptswap1 /swapfile /dev/urandom swap,offset=1024,cipher=aes-xts-plain64
然后...
sudo swapon -a # enable swap
free -h # review memory and swap usage
swapon -s # review swap summary
注意：gparted无法为您启动，因为您可能在 wayland 上运行 17.10 gnome。最好注销，然后在登录屏幕上单击齿轮并选择gnome on xorg，现在gparted（和其他应用程序）将正常运行。
答案3
我在 Dell Latitude E6540 上遇到了同样的问题。安装软件以读取 ex-fat 格式的 SD 卡后，我偶然解决了这个问题。
我运行了此命令：
sudo apt install exfat-fuse exfat-utils
关机时间很长的问题也消失了。
我不知道为什么，但它起作用了。
答案4
禁用 cryptswap。在大多数情况下，这是过度的，你应该从一开始就不要使用交换。
完成后，请报告，以便我们可以查找其他错误，因为现在大多数错误都与此有关。
其他罪魁祸首通常是等待关闭/超时的网络连接。
