![21.10 双屏停止工作](https://linux22.com/image/943560/21.10%20%E5%8F%8C%E5%B1%8F%E5%81%9C%E6%AD%A2%E5%B7%A5%E4%BD%9C.png)
我在华硕主板上运行 Xubuntu 21.10,带有原装内核(5.13.0-20)。内置英特尔 DVI 输出,以及带 HDMI 的 GeForce GT 430 卡。
我已经设置了很长时间,我的控制台上的 Intel DVI 显示 :0.0,连接到电视的 GT430 HDMI 显示 :0.1。一切都运行正常,直到最近,重启后没有 HDMI 输出,实际上根本没有显示 :0.1。
我搜索了网络,找到了很多不同的答案,包括使用 NVIDIA 驱动程序,但都不起作用。请帮忙:我的伴侣想念她的电视!

答案1
原来是电视机的间歇性故障,有时无法提供 EDID,导致默认显示分辨率错误,最终无法识别输出。我通过在启动命令行上提供“预设”EDID 来解决这个问题。
