因此，在近一年的完美表现之后，Ubuntu 开始表现得很奇怪。当我“挂起”时，屏幕会黑一秒钟，然后立即醒来但已注销。就像完全注销一样。它带我进入登录屏幕，然后我再次登录我的用户进入一个全新的会话。
现在，这是我的系统信息：
笔记本电脑：配备 RTX 3080 的 Alienware M17 R4
系统：Ubuntu 20.04，具有双启动和原始 OEM Windows 10
UEFI 安全启动已启用，我不想禁用它，因为它会扰乱 Windows。
我有外接键盘、鼠标和显示器，我尝试断开所有这些连接，但问题仍然存在。
我能想到的在这种行为之前最近发生的变化是：
我删除了 Wine 和 PlayOnLinux 并尝试将驱动程序恢复到 460，但这并没有解决问题。
我还尝试添加nouveau.noaccel=1到 grub 条目。
的输出systemd-inhibit --list --mode=block

如果我断开第二个显示器，它就会变成：

dmesg | grep suspend

我注意到了这里的注释，nomodeset但是一年前我第一次在这台笔记本电脑上安装 Ubuntu 时我使用了它来让它工作。一年来我对此没有任何问题。

该问题是由 Nvidia 驱动程序升级未能删除这些目录中新废弃的链接引起的：
/etc/systemd/system/systemd-suspend.service.requires/
/etc/systemd/system/systemd-hibernate.service.requires/
要删除的条目应如下所示：
nvidia-hibernate.service -> /lib/systemd/system/nvidia-hibernate.service
nvidia-resume.service -> /lib/systemd/system/nvidia-resume.service
按着这些次序：
这个问题仅影响我的 Ubuntu 笔记本电脑系统。我的 Ubuntu 桌面没有安装这些符号链接。
当系统从休眠或挂起状态恢复时，损坏的符号链接会导致 X11 sddm 崩溃。
