联想 T580 18.04 版无法休眠

我尝试搜索如何在 Ubuntu 18.04 上启用休眠模式,但是所有建议的方法都不适用于我。

我有一台联想 T580 ThinkPad,配备 SSD 磁盘,是 Windows 10 的双启动系统。

$ sudo systemctl hibernate
Failed to hibernate system via logind: Sleep verb not supported
$ sudo pm-hibernate
sudo: pm-hibernate: Command not found
$ cat /sys/power/disk
[platform] shutdown reboot suspend test_resume 
$ sudo apt-get install pm-hibernate
Reading package lists... Done
Buidling dependency tree

E: Unable to locate package pm-hibernate

我的/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).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/nvme0n1p5 during installation

/swapfile                                 none            swap    sw              0       0

$ swapon --show
NAME      TYPE SIZE USED PRIO
/swapfile file   2G   0B   -2

有什么建议么?

谨致问候,Steen

我在 X1 Carbon 7th Gen 上遇到了同样的错误。我做了以下操作来启用休眠模式(详细说明如下这里):

  1. 在 BIOS 中关闭安全启动。
  2. 在 BIOS 中关闭“现代待机”。
  3. 创建一个比我的 RAM 更大的交换文件。
  4. 更新 grub。

经过上述步骤,我可以使用sudo systemctl hibernate命令正常休眠和恢复。
