X Won't Start

Good afternoon.

I have an Ubuntu 18.04 installation that lately has gone a little haywire.

The system boots up seemingly fine, and X just never starts. (That is, all the startup text goes flying by, finishing with all of the daemon processes with the green [ OK ]s next to them, and then nothing else happens.)

/var/log/Xorg.0.log isn't much help either, as nothing new is getting written to it after restarting.

More info:

# lspci -k | grep -A5 VGA
73:00.0 VGA compatible controller: NVIDIA Corporation GP104GL (rev a1)
Subsystem: Dell GP104GL [Quadro P4000]
Kernel driver in use: nvidia
Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia
73:00.1 Audio device: NVIDIA Corporation GP104 High Definition Audio Controller (rev a1)
Subsystem: Dell GP104 High Definition Audio Controller

I tried updating Nvidia drivers, to no avail.

Thanks in advance for any suggestions!

Hi:
Not sure if your nvidia card uses the 304 driver or not but......
I found out the other day that the Nvidia 304 driver isn't supported in Ubuntu 18.04.

The cut off was 16.04:-

The only thing I can think of that you can try is run:

startx

HTH

nvidiafb, nouveau, nvidia_drm, nvidia

You need to blacklist nouveau when you have a nvidia card. The two can not co-exist.

Like this?

That should work.

Once nouveau is blacklisted X should start:-

Nothing new means nothing for us. You need to look for EE in that file, or post it. But if it was not written at all you need to check /var/log for any related messages, and/or you need to start X from command line and check that console.
But hopefully blacklisting will solve this issue.
