我在使第三個螢幕正常工作時遇到一些問題。
我的三個螢幕在 12.04 上運作良好，使用 2 個 nvidia 卡。全新安裝了 14.04，但在運行時遇到了無窮無盡的問題。
它要么被禁用，要么螢幕變黑，遊標呈 X。 Ubuntu 本機顯示設定甚至不會顯示第三個畫面。
我嘗試從舊安裝複製 xorg.conf，重新啟動 X 後，它在登入畫面上運行良好，但在我登入後它就坐在那裡，沒有執行任何操作（滑鼠仍在工作）。
我正在使用 gnome-session-fallback 而不是 unity，如果這有什麼區別的話。如果我嘗試統一，仍然會遇到這些問題。
如何讓我的第三個畫面運作並顯示桌面？
這是我目前的 xorg.conf

答案1
我有相同的配置，有 3 個顯示器。一台機器有2個顯示卡和3個顯示器。另外 1 個圖形和 3 個顯示器。
在兩台機器上，我必須將每個監視器配置為擁有自己的 xserver。
要配置它，我啟動 NVidia X 伺服器設定 (nvidia-settings) 轉到 X 伺服器顯示配置。在「設定：」下拉方塊中為每個監視器新增一個 xserver。也要啟用 Xinerama 複選框。根據需要組織顯示器。
按一下儲存至 X 配置並儲存在檔案 /etc/X11/xorg.conf 中。
現在您必須重新啟動或重新啟動顯示管理員。
有時（不是經常）我確實在重置配置時遇到問題，但隨後再次執行上述操作。
透過此配置，一些標準顯示配置工具（例如選擇螢幕保護程式等）將可用。
希望這可以幫助...
