I recently got an Nvidia card, after long debating I convinced myself that I earned a little gaming - tho I only used the machine for webdev. so far I have no experience with gcards and ubuntu.

I installed the driver, or at least I tried. I got some problem with the nouveau kernel - so whatever stumbled upon this thread

How to disable Nouveau kernel driver

Did whats posted on the accepted answer and now the pc won´t start.

I got 2 Kernels in the Advanced Menu (4.10.0-35 and 4.10.0-37) but in the root bash I also do not get any eth device to work, so no way of sudo apt-get update / upgrade.

Tomorrow I can get an USB Stick with 17.04 Live on it, any quick way to fix that with the Live Image? Recovery? Will it keep my files - I got an Backup, but not from my databases. So it would be nice to fix it.

Is there a log where I can figure out where the problem is?

  • You said that your PC won't boot. What do you mean? Are you having a login-loop (putting your password and instead of loading the desktop it's asking for password entry again)? – George Mathioudakis Oct 23 '17 at 21:05
  • Sorry, I shoul´ve been more specific. It stops when loading "Starting user manager with UID ..." on the boot process – Isengo Oct 23 '17 at 21:11
  • Please, if you can be more specific (as you said), edit your post and add more info. Do you have access to a root shell? Can you use apt-get update/upgrade/dist-upgrade? Do you have internet access? Can you boot on recovery mode kernel through "Advanced options"? – George Mathioudakis Oct 23 '17 at 21:24
  • I answered 2/3 already in my initial post. No internet / I can access the root shell and I can use the Advanced options. – Isengo Oct 23 '17 at 21:30
  • If you're on Wi-Fi, make a connection between your Computer and Router/Modem device via ethernet. Then, follow this guide in order to gain internet access via recovery-mode. Many users have solved the "Stuck on 'Starting user manager with UID'" problem by using apt-get update/upgrade/dist-upgrade. You can give it a try. – George Mathioudakis Oct 23 '17 at 21:45

Had the same issue.

There is a way to boot with Ubuntu "live CD" or "Live USB stick", then select "Try Ubuntu".

When in, you can mount your "broken" system in terminal with:

sudo mount /dev/sda2 /mnt

sudo mount --bind /dev /mnt/dev

sudo mount --bind /proc /mnt/proc

sudo mount --bind /sys /mnt/sys

sudo chroot /mnt

now you can delete all the nvidia stuff and revert the blacklisting....
