Mar*_*Eve 10 drivers xorg x11 nvidia multi-monitor
但是，类似于https://devtalk.nvidia.com/default/topic/719768/linux/304-121-ubuntu-14-04-xrandr-1-4-multi-gpu-not-being-detected上的报告/当我运行 xrandr --listproviders 时，我只看到一个提供者——第一张卡。我有 xrandr 1.4，所以应该能够看到两者。如果我设置一个单独的 X 屏幕，然后执行 xrandr --listproviders --screen 1，我可以看到第二张卡片。但是，我不想要多个 X 屏幕；我希望能够在显示器之间无缝流动。
我不想运行 xinerama，因为设置起来很麻烦，应该被 xrandr 取代。
使用 nouveau 驱动程序，我可以完全按照自己的意愿使用所有三个屏幕，但性能不佳。
所以，我有几个问题：
1.) 这种行为是设计还是错误？我在http://uk.download.nvidia.com/XFree86/Linux-x86/319.12/README/randr14.html注意到该驱动程序仅支持源输出功能；这会阻止我在 xrandr 中看到两个不同的卡提供商吗？
2.) 如果前者是真的，有没有办法解决这个问题？
3.) 我试过各种 basemosaic 选项，但无济于事
我尝试的最后一个配置是：

Martin-\n我这边的设置非常相似，除了一对 nvidia GT9800 - 大约 2008 年！还有一个板载 Intel HD4000（在 BIOS 中禁用）。xrandr 仅显示 1 个 GPU，但所有其他 sys 相关工具都正确报告了这两个 GPU。ubuntu 14.04 lts beta 2、nvidia 331.28 专有
\n\n昨晚我的圣杯修复是：基础马赛克！清空 xorg.conf，nvidia x 服务器设置 -> 启用 Base Mosaic，然后启用每个检测到的显示器。一切正常！快速无缝多 GPU、多头多显示器设置，带 1 个 xscreen！我的 3 台显示器分辨率不同，其中一台是纵向旋转的。甚至 ubuntu 设置 - 显示也能正确显示所有 3 个显示器。
\n\n我建议升级到 nvidia 331.28 专有驱动程序，删除 xorg.conf，然后再次尝试基本 Mosaic。
