Lonnie, I have this same laptop.  When booting the 3.14 or higher
kernels, you don't get a screen freeze at boot unless running
"nomodeset" or the proprietary Nvidia drivers?  I boot with the kernel
mode nomodeset, but then I don't have any way to control brightness.

Title:
  Toshiba Qosmio X75-A7298 - Can't Adjust Brightness

Status in The Linux Kernel:
  Unknown
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  The Toshiba Qosmio X75-A7298 is running Ubuntu 14.04 blazingly fast.

  The only issue I've noticed, is that the OS doesn't seem to have a
  proper mapping to this laptop's function keys.

  Specifically, I'm unable to adjust the screen's brightness. Looking a
  the keyboard layout, I should be able to dim the screen by holding
  down the FN key and then press F2. Alternatively, to make the screen
  brighter you'd key  FN-F3.

  This is a fantasic laptop, I'd like to help (if I can) to get it fully
  functional for Ubuntu 14.04.
