如何讓 xrandr 檢測兩個 nvidia 卡：2 x GTX480，三頭？
- 我正在執行 Linux Mint 16 (Petra)
- 我正在執行發行版附帶的預設驅動程序 nvidia-319
- 我有 2x GTX480 卡
- 我有 3 台顯示器
- 使用 Nvidia 驅動程序，所有顯示器和 GPU 都由專有實用程序拾取。
但是，與https://devtalk.nvidia.com/default/topic/719768/linux/304-121-ubuntu-14-04-xrandr-1-4-multi-gpu-not-being-detected上的報告類似/當我執行 xrandr –listproviders 時，我只看到一個提供者——第一張卡。我有 xrandr 1.4，所以應該都能看到。如果我設置一個單獨的 X 螢幕，然後執行 xrandr –listproviders –screen 1，我可以看到第二張卡。但是，我不想要多個 X 螢幕；我希望能夠在監視器之間無縫流動。
我不想執行 xinerama，因為設置起來很麻煩，應該被 xrandr 取代。
使用 nouveau 驅動程序，我可以完全按照我的意願使用所有三個螢幕，但性能並不好。
所以，我有幾個問題：
1.) 這種行為是設計使然還是錯誤？我在http://uk.download.nvidia.com/XFree86/Linux-x86/319.12/README/randr14.html注意到該驅動程序僅支持源輸出功能；這會阻止我在 xrandr 中看到兩個不同的卡提供商嗎？
2.）如果前者是真的，有沒有辦法解決這個問題？
3.）我玩過各種basemosaic選項，但無濟於事
我嘗試的最後一個配置是：

馬丁-我的設置非常相似，除了一對英偉達 GT9800 ——大約在 2008 年！還有一個板載 Intel HD4000（在 BIOS 中禁用）。xrandr 僅顯示 1 個 gpu，儘管所有其他 sys 相關工具都正確報告了兩者。ubuntu 14.04 lts beta 2，nvidia 331.28 專有
昨晚我的聖杯修復是：基礎馬賽克！清空 xorg.conf，nvidia x server settings-> Enable Base Mosaic，然後啟用每個檢測到的顯示。這一切都行得通！快速無縫多 GPU、多頭多顯示器設置，帶 1 個 xscreen！我的 3 個顯示器是不同的解析度，一個是旋轉的縱向。甚至 ubuntu 設置 - 顯示正確顯示所有 3 台顯示器。
我建議升級到 nvidia 331.28 專有驅動程序，炸掉你的 xorg.conf，然後再次嘗試 base Mosaic。
