昨天，我在 MSI-GS75 笔记本电脑上安装了新的 Fedora 36，一切都很顺利，直到大约半小时前。
笔记本电脑通过笔记本电脑上的 HDMI 端口连接到 65 英尺 4k 电视。它在一天的大部分时间里都运行良好，我正在测试将一些蒸汽游戏输出到电视上。
然后，笔记本电脑突然停止在 GNOME 显示设置中检测电视，原因不明。我运行了一些命令来查看它是否可以检测到 HDMI 输出或电视，但没有成功。
我已经测试过将电视连接到另一台计算机，效果很好，因此问题不在电视或 HDMI 电缆的一端。我尝试将另一个 HDMI 显示器连接到笔记本电脑，但也未检测到。
我注意到 xrandr 查询显示 HDMI 端口已断开连接，我尝试运行xrandr --output HDMI-1-0 --auto但没有成功
我将在下面列出终端输出，有什么想法吗？
