我有像这样的三台显示器设置。
这样一切都正常。但每当我将内置屏幕设置为较低的分辨率时，内置屏幕就会变黑。其他两个屏幕继续正常工作。当我将其重新设置为 1920x1080 时，它又恢复正常。屏幕空间似乎被渲染了，因为我可以将鼠标移到其中，并在其中放置窗口。我还可以截取它的屏幕截图。
但笔记本电脑屏幕上什么都没显示。背光亮着，仍然可以调节。系统设置就像一切正常一样。
我进行了一些搜索，也尝试了 ChatGPT，但是问题太具体了，我真的不知道要寻找什么。
我上线了Ubuntu 23.10. 笔记本电脑是HP Elitebook 845 G8， 与搭载 Radeon Graphics 的 AMD Ryzen 7 PRO 5850U。

我之前安装的 ubuntu Kubuntu 22.04 没有遇到任何问题。
有人能给我一些想法吗？我不知道该往哪个方向看。
答案1
2024 年 2 月 8 日更新
正如所见https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2046504Ubuntu 23.10 (Mantic) 已发布错误修复。因此，以下解决方案是不再适用于 Ubuntu 23.10 (Mantic)。正如@FabianStreitel 指出的那样，问题仍然存在于 Ubuntu 22.04 (Jammy) 上。
我还没有时间弄清楚如何切换回标准 Ubuntu 内核。
我设法通过安装较新版本的内核来使一切正常运行。（感谢@JanMolnár 的评论）
我用的是ubuntu-mainline-kernel.sh脚本来下载并安装不同的内核版本。
由于我启用了安全启动，因此我必须能够对不同的内核版本进行签名。我使用以下代码创建并注册了一个内核签名证书：ubuntu-sb-内核签名。
我在 ubuntu-mainline-kernel.sh 中打开了内核签名。
由于 Ubuntu 的版本是 6.5.0，所以我从 v6.5.1 开始，但从 v6.5.1 到 v6.5.8 的所有版本都出现了错误消息
Downloading index from kernel.ubuntu.com
Abort, the amd64 build has not succeeded
所以我最终使用了 v6.5.9。
同时，v6.5.1、v6.5.2 和 v6.5.3 中的 amd64 构建错误似乎已得到解决，其他错误可能也会得到解决。
我现在正在使用 v6.5.9，屏幕又可以完美运行了。
我希望有人能找到我的解决方案。如果有更好的解决方法，请告诉我 :)
正如 @JanMolnár 指出的那样，错误报告已在以下位置打开：https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2042867
