I just performed a suggested update by the Update Manager on Ubuntu 14.04, and now I get no video when I reboot.

I get the splash screen, then it goes black.

Can I somehow switch back to default X drivers from terminal?


Had the same problem today, here's what helped me:

  1. Boot into recovery mode and get into root shell (screenshots).
  2. Make root partition writable: mount -o remount rw /
  3. Remove all nvidia packages: apt-get remove --purge nvidia*
  4. Reboot into normal mode: reboot

Now you are using open source Nouveau driver. If you wish, you can reenable Nvidia binary driver.

  • This is exactly what I did, by putting a few other posts from various locations together. I do appreciate the response! Well done!

Reboot and enter into recovery mode By Pressing SHIFT Key

After reaching the menu choose drop to shell

Then execute the command

sudo mount -o remount rw /

Edit the file

# sudo gedit /etc/default/grub

And modify the line :


It to obtain this line :

GRUB_CMDLINE_LINUX_DEFAULT="acpi=noirq acpi=force apm=power_off quiet splash"

Then, save, close, and back in the terminal, execute :

# sudo update-grub

Now, when you will Shutdown, it should Work great.
