[Bug 1464530] [NEW] Black screen after Kernel update Dell XPS15, NVidia GeForce GT 750M

 

Public bug reported:

$ lsb_release -rd
Description:	Ubuntu 15.04
Release:	15.04

After upgrading to the kernel version 3.19.0-20-generic I only see a black screen when the login screen should appea.
I can hear the "drum roll" of the login screen, so I guess it's  a problem with the graphics driver / display manager.

I'm currently using the NVIDIA binary driver - version 346.59 from nvidia-346-updates (proprietary).
I've already tried every other NVIDIA driver offered in the "Additional Drivers Tab" for "Software and Updates".

Booting with the previous kernel 3.19.0-18-generic works fine.

The machine is a DELL XPS 15 model from 2015.

Title:
  Black screen after Kernel  update Dell XPS15, NVidia GeForce GT 750M

Status in lightdm package in Ubuntu:
  New

Bug description:
  $ lsb_release -rd
  Description:	Ubuntu 15.04
  Release:	15.04

  After upgrading to the kernel version 3.19.0-20-generic I only see a black screen when the login screen should appea.
  I can hear the "drum roll" of the login screen, so I guess it's  a problem with the graphics driver / display manager.

  I'm currently using the NVIDIA binary driver - version 346.59 from nvidia-346-updates (proprietary).
  I've already tried every other NVIDIA driver offered in the "Additional Drivers Tab" for "Software and Updates".

  Booting with the previous kernel 3.19.0-18-generic works fine.

  The machine is a DELL XPS 15 model from 2015.
