我有一个这样的三显示器设置。
一切都像这样工作正常。但每当我将内置屏幕设置为较低的分辨率时，内置屏幕就会变成空白。另外两个屏幕保持正常工作。当我将其设置回 1920x1080 时，它又恢复了。屏幕空间似乎已渲染，因为我可以将鼠标移入其中，并将窗口放入其中。我还可以截图。
但笔记本电脑屏幕上什么也没有显示。背光已打开且仍可调节。系统设置就像一切都很好。
我做了一些搜索，也尝试了 ChatGPT，但问题非常具体，我真的不知道要寻找什么。
我在Kubuntu 23.10上。该笔记本电脑是HP Elitebook 845 G8，配备AMD Ryzen 7 PRO 5850U 和 Radeon Graphics。

我在之前的 ubuntu 安装（Kubuntu 22.04）中没有遇到任何问题。
有人可以给我一些想法吗？我不知道该往哪个方向看。
我设法通过安装更新版本的内核来使事情正常工作。（感谢@jan-molnar 的评论）
我使用ubuntu-mainline-kernel.sh脚本下载并安装不同的内核版本。
由于我启用了安全启动，因此我必须能够签署不同的内核版本。我使用ubuntu-sb-kernel-signing创建并注册了内核签名证书。
我在 ubuntu-mainline-kernel.sh 中打开了内核签名。
由于 Ubuntu 是 6.5.0 版本，所以我从 v6.5.1 开始，但从 v6.5.1 到 v6.5.8 的所有版本都给出了错误消息
所以我最终使用了 v6.5.9。
amd64 构建的错误似乎同时在 v6.5.1、v6.5.2 和 v6.5.3 上得到解决，其他版本也可能得到解决。
我现在使用的是 v6.5.9，屏幕再次完美运行。
我希望有人会使用我的解决方案。如果最好以不同的方式解决这个问题，请告诉我:)
正如 @jan-molnar 指出的，错误报告已在以下位置开放：https ://bugs.launchpad.net/ubuntu/+source/linux/+bug/2042867
