Title:
  Kubuntu 14.04 freezes after LightDM login

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I have re-setup my notebook with Kubuntu 14.04. I have an nVidia
  Optimus platform and hence wanting to try out kerne 3.12 with native
  switching support. Also the whole system is encrypted with LUKS/dm-
  crypt.

  At bootup I get nicely prompted for the LUKS key, I enter it and
  afterwords I end up at LightDM. I provide the password there and then
  the KDE screen appears on which different icons would appear within
  seconds. However the computer freezes at that point - or rather the
  display freezes.

  I tried to ctrl-alt-f2 but that didn't open a terminal.

  Upon suggestion, I then tried to ssh into the computer. That worked
  fine.

  So it seems there are graphic problems or something. In order to use
  that installation I currently use the Saucy kernel.

  While SSHing I made a backup of the whole /var/log folder. I don't
  know which of them are relevenat but I can provide them when asked.

  According the lshw I have:

  product:	GF119M [GeForce GT 520M]
  vendor:	NVIDIA Corporation

  and

  product:	2nd Generation Core Processor Family Integrated Graphics Controller
  vendor:	Intel Corporation
