Ubuntu20.04无法挂起。在尝试暂停后，X应用程序将关闭。

Question

我有一台Ubuntu 20.04的电脑。安装Ubuntu20.04后，挂起工作正常，但不久前它停止工作。

我按下菜单中的暂停按钮，在屏幕变黑几秒钟后，球迷继续旋转。在那个屏幕打开后，我看到一个登录屏幕。当我输入密码时，我看到所有的X应用程序都被销毁了。

我尝试了不同的内核，但结果是一样的。

cat /proc/acpi/wakeup命令给出了下一个结果：

journalctl -b | grep suspend命令显示了下一个错误：

I tried to install Unity desktop instead of Gnome but result is the same except it doesn't kill X applications.

In my ```/var/log/syslog``` I see the next troubles connected with suspend:

```Feb  8 21:39:04 user-pc ModemManager[1208]: <warn>  [sleep-monitor] inhibit failed: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying

2月8日21:39:04用户-pc系统1：systemd-logind.service: Failed和结果'exit-code‘。

下午-暂停正常，但有时不醒。

你能帮我一下吗？

我的个人电脑有AMD 6450 gpu和Nvidia Tesla K20m gpu。在我完全重新安装两个gpu驱动程序到专有驱动程序之后，问题就消失了。
