我有雙 Geforce GT1030，帶有 4 個顯示器。我正在嘗試啟用所有 4 個選項，以便我可以在擴展監視器顯示中使用它們中的每一個。
我運行了 sudo add-apt-repository ppa:graphics-drivers/ppa，並選擇了 nvidia-384.111、390.25 和 387.34，無論哪種情況，我都會更改：選項“Xinerama”“0”從 0 到 1重新啟動，螢幕啟動，出現紫色螢幕，然後變黑。像顯示器一樣的黑色就是生命（我可以看到遊標），但沒有 ubuntu 會話或登入畫面。
在 384.111 上，我在 gdm3 配置下完全禁用了 Wayland，看看這是否是一個問題，但它似乎沒有改變任何東西（nvidia 驅動程式似乎默認情況下可能會這樣做？）。
下面是我的 xorg.conf 供參考：

答案1
最終，當啟用Xinerama 時，Unity/Gnome3 在雙GT1030 上遇到了困難，詳細的原因我不確定，但當我切換到我的問候語和顯示管理器時，我似乎更進一步，所以我的解決方案是切換到完全交給 Xubuntu，它不僅解決了我的問題，而且看起來很有效，而且工作得很好。
