Mi GPU es la GTX870M. Hice una instalación nueva de Ubuntu 18.04. Todo lo que hice fue:
sudo apt-get update
sudo apt-get upgrade
sudo ubuntu-drivers autoinstall
nvidia-xconfig
reboot
Instaló el controlador nvidia-390. Ahora, cada vez que intento iniciar el servidor X, startxfalla. Todavía puedo usar Wayland. Esto es lo que probé (en modo de recuperación):
startx

¿Parece que mi dispositivo de visualización no se detecta correctamente y/o que el servidor X está intentando utilizar demasiada memoria?

Parece que su controlador no puede encontrar la resolución del monitor. Es posible que tengas que configurarlo manualmente. ¿Has probado esto?

Mi sistema es un Skylake 6700HQ con nVidia GTX 970M, por lo que es bastante parecido al tuyo. He estado usando el controlador 384.130con gran éxito desde el primer día y nunca lo cambié. Solo tuve una peculiaridad: Windows enciende el sonido en la tarjeta nVidia, pero Linux no. Entonces tuve que aplicar un parche llamado nvhdapara poder obtener sonido HDMI en mi televisor.
