我在 Lenovo Ideapad 上使用 Ubuntu 20.04 版本
每当我锁定我的笔记本电脑（或者它被锁定在不活动状态）并尝试解锁时，我的显示屏就会崩溃。我看到如下屏幕
我有另一个外部显示器连接到这台笔记本电脑，并且该显示器看起来不错。
这种情况是在几天后才开始发生的。我还尝试查看是否有任何最近的更新导致了此问题。但我看不到任何相关内容。这是日志。

我有双启动。因此在 Windows 上尝试了同样的操作，即使在锁定屏幕后也能正常工作。我不知道 Ubuntu 中是否有任何视频驱动程序受到干扰。请任何帮助！
答案1
我有一台联想笔记本电脑（AMD 架构）也有同样的问题。问题出在最新更新的内核 5.13 中。
通过输入此命令检查您的内核版本
uname -r
如果您使用的是 5.13 或更高版本，则可以通过降级到较低版本（例如 5.11）来解决该问题。
这不是最终的解决方案，但在新补丁发布之前它可以为您提供帮助。
有一些教程可能有用：
答案2
正如建议的杜岱在他的回答，我检查了内核版本，确实是5.13。
然后，我检查了在安装 5.13 之前还有哪些其他版本，方法是：
dpkg --list | grep linux-image
选择旧版本 5.11.0-44 并再次安装
sudo apt install linux-image-5.11.0-44-generic
并启动到这个 5.11 内核。它解决了显示问题，但很多事情都不起作用。比如网络、外接显示器等...
尝试通过执行 a 来比较其他已安装内核的所有安装dpkg --list | grep linux-，发现 5.11 缺少 module-extra 软件包
引导回新内核（可以工作但有显示问题的内核）并安装缺少的软件包
sudo apt install linux-modules-extra-5.11.0-44-generic
启动进入 5.11，一切正常
