我在我的 lenovo w520 上全新安裝了 ubuntu gnome 16.04(沒有格式化主分割區;在我安裝 ubuntu gnome 15.10 之前)。我的筆記型電腦(遺憾的是 - 因為我總是遇到麻煩)安裝了 nvidia Quadro 2000M(支援 optimus)。 15.10 以下一切正常。現在,當我安裝 nvidia 專有驅動程式 (nvidia-361) 時,無法偵測到筆記型電腦螢幕。如果我插入外接顯示器,則工作正常,但筆記型電腦螢幕永遠無法工作。有人有主意嗎?我已經嘗試重新配置 xorg,我刪除了 ~/.config/monitors.xml 檔案。還能是什麼?是否可能在主目錄中保留了舊安裝的某些配置?

看來是361驅動的問題。安裝舊版並不能解決問題,但透過 ppa 安裝 364 可以解決問題。
