Bounty: 50

I have Ubuntu 16.04 on a Gigabyte Aero 14 laptop having Geforce GTX 1060 VGA. Using different nvidia drivers results in different behavior. For example, “nvidia-384” and “nvidia-387” don’t detect the second monitor.

Currently, I have installed nvidia-390 (tried both .run file from nvidia website, and the package from ppa:graphics-drivers/ppa). It works when the external monitor is attached, but when I disconnect the monitor and reboot, ubuntu crashes after login.

Some notes:

  • I have already tried Ubuntu 16.04 + Nvidia Driver = Blank screen
  • Reinstalled drivers
  • Tried both UEFI disabled and enabled
  • Tried Unity and Gnome
  • Nouveau driver, nvidia-367, nvidia-384, and nvidia-387 don’t detect my second monitor
  • Tried both mini-display to VGA port, and HDMI to HDMI
