Cannot run nvidia driver on ubuntu 18.04, geforce mx250

Hello, I have a problem installing nvidia drivers on a Dell Inspiron 7000 with GeForce MX250 - blank screen.

I have tried every step here: Black screen after install of nvidia driver ubuntu

With intel drivers (prime-select intel) ubuntu loads ok with GUI - native resolution, and can’t connect external displays.

Nvidia drivers 450 are in use. When I do prime-select nvidia and reboot, after a while the ‘drums’ sound from lightdm can be heard, but there is a blank screen, text mode, with a cursor.
Ctrl-alt-Fxx still lets me go to a terminals and do modifications.

Here is some more context, and output of various files and commands I saw requested in other reports appear below:

  • using nvidia driver 450 (tried 435 too)
  • There are no xorg.conf files anywhere (except one in /usr/share/doc). Contents of /usr/share/X11/xorg.conf.d/* are attached below.
  • Secure boot is disabled at BIOS
  • Using lightdm, but tried gdm3 and it would crash
  • nvidia driver IS loaded (see lsmod below)
  • I DO have a blacklist modprobe option (old, nouveau), which I think is irrelevant (see commands below)

Not sure what other info helps debugging this. I am attaching the output of many commands and the nvidia bug report too in a next message.
