一次不能使用 2 台以上显示器

一次不能使用 2 台以上显示器

我最近购买了一台新显示器和适配器线,以便将 3 台显示器连接到我的桌面

但是,第三个监视器上不会显示任何内容

我尝试调换电源线,发现显示器和适配器都可以工作,但由于某种原因,我的系统一次不会显示超过 2 个显示器,因为我只需断开一个显示器即可让新显示器正常工作我的另外两个显示器,但重新连接它们将使它们不再显示

我启动了 Windows 和 Ubuntu,两者都可以在所有 3 个显示器上显示,所以我知道这不是硬件问题,也不是一般 Linux 的问题,而是与我的安装有关的问题

这是一些信息

我的主要两台显示器是 DVI 和 HDMI(通过 HDMI 转 DVI 适配器),而新的第三台是 Mini-DisplayPort 转 DVI 适配器

这是“xrandr --verbose”的输出

如果我尝试使用“xrandr --output DisplayPort-0 --mode 1366x768”手动设置显示器模式,我会收到错误“xrandr:配置 crtc 1 失败”

尝试使用 arandr 进行相同的操作会产生相同的错误
