Title:
  HP ZBook 15 Try Ubuntu via Live DVD freezes system after a while

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  machine:  HP ZBook 15 
  (Intel Core i7 4700MQ Haswell, NVIDIA Quadro K1100M 2GB, 1920 x 1080 display)

  system: ubuntu 13.10 desktop, 64-bit, live DVD  (md5 sum OK)

  I boot from the live DVD. The boot goes fine.
  Then I decide to try the ubuntu (not to install).
  I go to the search in the left upper corner, type "terminal".
  I open the terminal.

  After a while the desktop environment almost completely freezes. I can only move the touchpad pointer.
  I can also switch to the console (Alt Ctrl F1) and then back (Alt F7). The desktop responds after this switch but its reactions and colours are strange and it is unusable.

  I guess a problem with a video driver. I am not sure which one because
  there are two graphics processors inside (one is an embedded Intel HD
  Graphics 4600, the other is the NVidia, see above).

  However, I have similar problems when I insert the DVD into an old
  computer: 1st generation Intel i7, without an embedded graphics, with
  two dual cards GeForce GTX295 (4 GPUs together). The machine runs fine
  older Ubuntu and Mint releases.
