After updating to Ubuntu 15.04, the screen goes blank when I boot Ubuntu with grub2. I have tried most of the posted solutions (adding nomodeset, changing quiet splash to no splash) but to no avail. What can I do? (I can't access ubuntu's terminal, but I do have access to Windows10)

When the GRUB boot menu appears : Highlight the Ubuntu menu entry and press the E key.
Add the nouveau.modeset=0 parameter to the end of the linux line ... Then press F10 to boot.

When the login screen appears press Ctrl+Alt+F1.

Enter your user name and password.

Identify your NVIDIA graphics hardware by executing:

lspci -k | grep -EA2 'VGA|3D'  

Uninstall every NVIDIA related software by executing:

sudo apt-get purge nvidia*  
sudo reboot

When the GRUB boot menu appears : Highlight the Ubuntu menu entry and press the E key.
Add the nouveau.modeset=0 parameter to the end of the linux line ... Then press F10 to boot.

When the login screen appears press Ctrl+Alt+F1.

Enter your user name and password.

Install the NVIDIA drivers by executing:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-*
sudo reboot  

Note 1:

As you did not provide any information about your NVIDIA graphics card check drivers versions.
Replace * with the latest stable main version number (e.g. 355) that supports your NVIDIA GPU.

Note 2:

When you have switchable graphics cards install nvidia-prime (NVIDIA Optimus support) as well.

Note 3:

If you ever have had bumblebee installed before to switch between graphics - also remove this.

  • Thank you for your help. I tried adding nouveau.modeset=0 and the screen remain blank after booting. I can't seem to access the login screen. – ke.li Nov 13 '15 at 14:43
  • @KevinLiang : Maybe something serious went completely wrong while performing the upgrade process ... Make a clean install of Ubuntu 15.10 and after having finished, follow the instructions ... Ubuntu 15.04 will be unsupported soon anyway ! :) – cl-netbox Nov 13 '15 at 14:46
  • should it look like this? linux /boot/vmlinuz-3.16.0-15-generic.efi.signed root=UUID=df64fe7e-52dd-4529-a9cb-c9df63503f96 ro quiet splash $vt_handoff nouveau.modeset=0 – ke.li Nov 13 '15 at 14:51
  • @KevinLiang : yes - but I wonder about this kernel you use ... Ubuntu 15.04 has kernel 3.19 ... :) – cl-netbox Nov 13 '15 at 14:53
  • How do I figure this out? does this affect the code? – ke.li Nov 13 '15 at 16:06
