Ubuntu 20.04 中的三显示器设置

Ubuntu 20.04 中的三显示器设置

我有一台运行 Ubuntu 20 的联想 Thinkpad E531。我想使用笔记本电脑上的 VGA 和 HDMI 接口连接两个外接显示器。

我遇到的问题是 xrandr 不会显示多个外接显示器。更多信息如下:

xrandr:配置 crtc 2 失败

我尝试使用 ubuntu 显示设置。尝试使用 xrandr 和 arandr。我尝试设置一个接一个的显示器。我尝试使用 xrandr 进行不同的设置。

我得到的最好的东西是两个外接显示器镜像和扩展笔记本电脑屏幕。有人能告诉我解决方案的方向吗?

输出操作系统xrandr --listproviders是:

Providers: number : 1
Provider 0: id: 0x48 cap: 0x9, Source Output, Sink Offload crtcs: 3 outputs: 6 associated providers: 0 name:modesetting

xrandr:

这是一个跨站点的问题。总结一下:

使用基座(扩展坞),然后安装最新的适用于 Ubuntu 的 DisplayLink USB 图形软件适用于你的 Ubuntu 版本20.04
