我使用的是 4 显示器系统,几天前一切都运行良好。在其中一台计算机重新启动后,DVI-D-0 输出上的显示器停止显示图像,显示“无信号”。我从实时系统启动,在这种情况下,所有 4 个显示器都显示图像。在主系统上,所有显示器都在设置中定义,在 inxi 和 nvidia-settings 中。这不是 xorg 或其他什么问题,因为即使我在没有 sddm.service 的情况下仅在 tty 中启动时它也无法工作。
配置:
Arch linux x86_64,内核 6.9.7-arch1-1,KDE Plasma 6.1.1,CPU:i5-13600kf,GPU:GTX 1080ti,32Gb DDR4
编辑:
我尝试重新安装 linux-base,但它甚至在紧急模式下都无法工作。接下来,我将 kde-plasma 更改为 i3wm。

我尝试了另一个问题中关于同一主题的其他建议,但没有用。建议如下:
xranrd --xrandr --output DVI-D-0 --off
xrandr --output DVI-D-0 --mode 1600x900 --pos 1600x0
