[Just Asking For A CD <1280613@xxxxxxxxxxxxxxxxxx>]

After much tinkering I could make it work for Xubuntu 14.10. More or
less.

Optirun works for FireFox but won't for Chromium. No clue why this is.

At some point during my attempts I saw in nvidia-settings a profile choice: Intel or NVidia. (Without running optirun.) Intel worked fine. NVidia crashed the machine. Never saw that again.

Title:
  Nvidia Optimus + bumblebee configuration not optimized by default

Status in Bumblebee: NVIDIA Optimus for Linux!:
  New
Status in nvidia-graphics-drivers-331-updates package in Ubuntu:
  Confirmed

Bug description:
  Hardware configuration is a ThinkPad T540p with GeForce GT 730M. I
  understand that this graphics chip as some new fangled "Nvidia
  Optimus" technology involved.

  I began testing with Xubuntu 13.10 x64, then re-imaged the system with
  the Alpha build of Xubuntu 14.04 x64 of 20140214.

  I have had to do extensive hand editing to the configuration of
  selecting both nvidia-graphics-drivers-331-updates and the bumblebee
  packages in order to at least see the Nvidia driver "active" in the
  Nvidia Settings applet.

  I have been updating the modprobe configuration:
  /etc/modprobe.d/bumblebee.conf
  commenting out the exclusions for the 331 version driver

  I have updated the bumblebee configuration:
  /etc/bumblebee/bumblebee.conf
  according to the example found here:
  http://elementaryforum.org/forum/support-assistance/how-to_aa/3996-nvidia-optimus-drivers-and-tools-installation#post3997

  To get the NVIDIA Settings to show the board finally...

  I found this command here:
  "Nvidia Optimus on Linux" \ "How to use Bumblebee."
  http://www.linux.org/threads/nvidia-optimus-on-linux.4415/

  optirun -b none nvidia-settings -c :8

  However starting an additional instance of the NVIDIA Settings applet
  via the Xubuntu menu system shows that instance not being able to
  detect the Nvidia drivers being loaded. So it seems that one must use
  the optirun command to start individual programs that the Nvidia
  drivers are requested to service the video for?! This makes absolutely
  no sense.

  Shortly I am seeking automatic configuration of the latest Nvidia
  binary drivers to be used 100% of the time. Even the old Envy Nvidia
  binary driver installer worked far more simply than dealing with this
  "Nvidia Optimus" technology. "Needs improvement."
