已经尝试了在线找到的几个修复方法，但均不起作用。:(
设置：
- 联想 L15 笔记本 Gen3 - 1920x1080px 60Hz
- AOC Q3279VWFD8 显示器 - 2560x1440px 75Hz
- HDMI 线（没坏，可以在我的电脑上使用）
尝试在设置->显示中为 AOC 提供相同的分辨率和刷新率，但没有效果。
最奇怪的是，我试了几天，大约 20 次，只有一次真的成功了。从那以后，再也没有成功过。尝试“逆向工程”先插入笔记本电脑，先插入屏幕，关闭电缆，在睡眠模式下连接，插入时打开/关闭屏幕，但都没有成功。
我的笔记本电脑没有 Nvidia 显卡，所以网上所有这些 Nvidia 修复方法对我来说都不起作用。
这是我的 xrandr 终端结果：

答案1
最近，联想笔记本电脑经常出现这个问题。有些笔记本电脑不得不禁用 UEFI 并启动旧版系统，而有些笔记本电脑则不得不更新 BIOS。查看该型号的故障排除，它说您必须按 Fn + f7 或 Win + P 才能激活它。 https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t15p-gen-3-type-21da-21db/troubleshoot
如果您已经完成了该组合键，我建议您检查您的 BIOS 版本，并尝试在没有 UEFI 的情况下启动，看看是否有任何不同。我曾经遇到过一台旧戴尔笔记本电脑和 wifi 的问题，为此我不得不将 dell_laptop 列入黑名单，所以有时是 BIOS 的问题。希望这能有所帮助，或者其他人有建议。
