我正在尝试在我的笔记本电脑上启用第三个屏幕，该笔记本电脑配有英特尔 + NVIDIA 混合显卡，但没有成功。我使用 Bumblebee 来管理这两张卡。
在图形监视器配置中，系统可以看到 3 个监视器，如果我选择镜像监视器选项，我可以使其工作，但如果尝试将它们选择为 3 个独立桌面，则会出现此错误：
无法应用配置：%s
如果我尝试这个 xrandr 命令：
xrandr --output VGA1 --auto --right-of LVDS1
错误是：
xrandr：无法找到输出 VGA1 的 crtc
xrandr --current 的输出：

如你所见，虽然 VGA1 没有工作，但 3 个显示器已连接
