我在这里尝试了很多方法来解决这个问题，但都不起作用。我使用的是 HP-Pavillion，配有 Intel 620 显卡，1TB 固态硬盘和 12GB 内存。
我已经使用 Windows 10 双启动系统，并且系统确实可以通过 Windows 10 唤醒。
在我重新安装 Ubuntu 之前，系统也曾经唤醒过。
我注意到显示屏完全是黑色的，但键盘确实亮了。
Ctrl-Alt F3或者F7根本不起作用。
我的交换空间如下：
$sudo swapon --show
NAME TYPE SIZE USED PRIO
/home/swapfile file 8.5G 0B -2
我尝试过设置noveau.modeset=0，也尝试过从切换到lightdm，gdm3但都无济于事。
我检查了系统日志journalctl | grep systemd-sleep并得到了这个结果。

所以它确实会在睡眠后恢复。有谁知道哪里出了问题吗？任何帮助都将不胜感激。谢谢。
