我有一个连接到 KVM 切换器的双显示器设置(链接:https://es.aliexpress.com/item/1005005992520783.html?spm=a2g0o.order_list.order_list_main.147.21ef194de9qFxg&gatewayAdapt=glo2esp),其中一个显示器通过 HDMI 连接,另一个通过 DPI 连接。我运行的是 Kubuntu 23.10,采用默认屏幕显示设置。笔记本电脑屏幕(Thinkpad)在配置过程中被禁用。
我遇到的问题是,一个或两个屏幕会随机变黑。有时是一个屏幕,有时是另一个屏幕,有时是两个屏幕。重新启动系统通常可以暂时解决问题。
我尝试使用 arandr 等替代方案来配置显示设置,但问题仍然存在。我不确定如何排除故障或解决它。
运行lspci ; xrandr
将返回以下内容,并在几秒钟内使辅助屏幕变黑:
