系统规格 #

• 笔记本型号：Clevo NP50PNH
• Ubuntu版本：22.04
• 内核版本：6.2.0-26-generic
• 显示服务器：Wayland
• 显卡：NVIDIA GeForce RTX-3060（6GB DDR6显存，DirectX 12.1，115W TDP）+ 英特尔Iris Xe核显

问题描述 #

大概一天前，我的工作笔记本上的NVIDIA RTX 3060突然失效了——HDMI接口直接用不了，只有USB-C雷电接口还能外接显示器。我发现系统自动切回了英特尔Iris Xe核显，更奇怪的是，现在打开“附加驱动”界面时，显示没有可用的额外驱动，之前明明有一堆选项可以选。

之前因为NVIDIA专有驱动闹过不少问题，我用了一个多月的nouveau开源驱动。作为编程用的工作本，我不需要花里胡哨的显卡功能，只要能正常用HDMI就行。目前我的apt已经更到最新状态，笔记本BIOS选项少得可怜，所以暂时没碰BIOS相关的操作。

另外还有个小问题：现在关机或重启经常卡住，等好几分钟都没反应，必须长按电源键5秒才能强制关机，不确定这和显卡失效有没有关系。

已尝试的操作 #

• 执行apt update && apt upgrade更新系统
• 检查“附加驱动”界面，无可用驱动
• 尝试用prime-select nvidia切换到NVIDIA显卡，重启后没效果
• 多次重启系统
