我拥有的
- 两张视频卡。英伟达 1050 和 英伟达 1050 Ti
- 四个显示器。一种是 4k，一种是全高清，两种是 1920x1200。最后两个是纵向模式。
我的显示器是这样放置的：

现在如何运作
所有显示器均连接至 1050 Ti。作品。配置是这样的：

--output "HDMI-0" --mode 1920x1200 --rate 60 --right-of "DP-0" --rotate left \
启动时，X 接收有关卡和监视器的信息。此外，当窗口管理器启动时，将执行 xrandr 初始化脚本，并将监视器部署并对齐到我需要的位置。
我想要的是
- 将 4k 显示器连接到 1050 Ti
- 将其他显示器连接到 1050
也就是说，我想在两个显卡之间分配负载
我尝试过什么
将三个显示器切换到第二个显卡。
兰德尔
更改初始化脚本不会给出结果。 xrandr 不想轮换显示器。错误是这样的：xrandr: output HDMI-1-0 cannot use rotation "right" reflection "none"此外，如果我删除旋转选项，监视器将不会启动。仅活动的 4k 显示器连接到主显卡。

nvidia 设置
我还尝试使用 nvidia-settings 配置 xorg.conf。显示器初始化正确，侧面显示器旋转正确。但是当我启动 opengl 应用程序时（例如，猫咪），界面开始变慢。桌面/窗口之间的切换开始变慢很多（切换需要几秒钟）。同时nvidia-smi dmon显示1050已加载100%：
