Title:
  Cannot login with Nvidia Optimus hardware installed(Ubuntu 15.04)

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  I have Nvidia Optimus GT415M hardware on my laptop.

  I've upgraded my Ubuntu 14.10 where everything was working fine with
  Nvidia Optimus  to Ubuntu 15.04 and now I cannot login. After I type
  the password login screen comes back again.

  I did complete reinstall of NVidia packages and installed new
  nvidia-346 package from Ubuntu repo.

  Looking at Xorg.0.log I see this message:
  [   120.353] (EE) intel(G1): [drm] failed to set drm interface version: Permission denied [13].
  [   120.353] (II) intel(G1): [drm] Contents of '/sys/kernel/debug/dri/0/clients':
  [   120.353] (II) intel(G1): [drm] a dev	pid    uid	magic
  [   120.354] (II) intel(G1): [drm] 
  [   120.354] (II) intel(G1): [drm] y   0  2996     0          0
  [   120.354] (II) intel(G1): [drm] y   0  2996     0          0
  [   120.354] (EE) intel(G1): Failed to claim DRM device.

  And I have found thread regarding this problem on
  https://devtalk.nvidia.com/default/topic/816599/prime-switching-to-
  nvidia-creates-black-screen/. So looks like hardware similar to mine
  need a new version of xserver-xorg-video-intel.

  Could you please help with this.
