N卡: rtx 3050
桌面环境:gome
问题描述: 外接显示器没有信号 我觉得外接显示器接口走的可能是N卡的输出 然后我就安装了nvidia, nvidia-utils, lib32-nvidia-utils。 并使用optimus-manager 进行管理,不管是切换到nvidia模式,还是核显模式外接显示器都没有输出。
--------------------------------------------------------------
以下是nvidia模式下的一些输出:

这个问题我折腾两年了,愣是没搞好,显示器能识别到,就是不出桌面

我也遇到了这个问题,但我的问题出现在wayland下,x11可以正常输出,你可以确认一下自己是否在使用wayland会话
