After upgrading from 17.10 to 18.04.1 everything was fine (means my X-session came up in mode 3840x2160_30) when I had installed the Nvidia 390 driver.
After a second reboot the GDM3 login screen was still fine but when logging in into my userid (501) screen went black and did not recover. This is reproducible.
Reverting to Nouveau driver seemed to solve the problem, but after a couple of reboots (3-5) Nouveau comes up with mode 1024x768 without any choice.
Now I updated to Nvidia 396.54 downloaded from PPA, it works up to GDM3 login screen but after the login it goes black again.
Following is the Xorg.1.log
Any help or advice much apprechiated.
