Ubuntu 16.01 如何双显示屏？

Question

使用 xrandr 并没有用，装了 nviDIA 驱动导致 ubuntu 导致桌面 dock 显示不了，求双显示屏方案。

Answer 1

It should be that you installed xrandr but it doesn’t work. I don’t use the unity desktop, but I always use xrandr for multi-screen display.

The dock cannot be displayed and it has nothing to do with multi-screen display.

See Multihead and xrandr for solutions
