Ubuntu 18.04 hangs at boot after running `nvidia-xconfig`

  • 772

Ubuntu 18.04.4 stuck at the loading screen after running the following command and rebooting:

sudo nvidia-xconfig

I forcefully shut it down a couple of times and when I started it again it still hangs there.

enter image description here

I'm standing here looking at the screen and I can't believe that NVIDIA is a 230 bln $ company.

What solutions are there? Is there any way I could access the terminal from here in order to delete the xorg.conf file?

If I press ctrl+alt+F4, it takes me to a screen which says:

xHCI host controller not responding, assume dead
A start job is running for Hold until boot process finishers up
boot nvidia

  1. This worked for me:

    At startup, press Esc. Right after the logo disappears press once, don't press it too many times to get to grub.

    In the next window I had 3 options:

    Ubuntu
Advanced options for Ubuntu
System setup

    Choose Advanced options for Ubuntu. Next, select:

    1. Ubuntu with Linux *version* (recovery mode)
    2. root
    3. OK.

    Press Enter once and type:

    rm /etc/X11/xorg.conf
reboot

    Worked fine. But now I have another question: I was not required to enter my root password, anyone could have altered my system. What can I do to protect root access?
