Comment 6 for bug 1249067

This morning (20140205 @ ~8am AEDST) accepted an update on my system (nvidia-prime amongst others). However, I was unable to login afterwards. After prowling my /var/log folder, I came across /var/log/nvidia-prime-upstart.log (attached) which suggested that nvidia-prime was the issue. I was then able to login to my desktop (degraded graphics mode - max res 1024x768) and do a Google search which brougt me here.

Having never manually submitted (I believe my laptop automatically collects info about my laptop before it submits a bug when something crashes) a bug report on Launchpad, please bear with me:

Laptop details:
Manufacturer: Dell Precision M6700
CPU: Intel(R) Core(TM) i7-3840QM CPU @ 2.80GHz
Onboard Video: 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
Discrete Video: 01:00.0 VGA compatible controller: NVIDIA Corporation GK104GLM [Quadro K3000M] (rev ff)
OS: Ubuntu 12.04.3 LTS
Kernel: 3.9.0-030900-generic (from Saucy Salamanda to fix issues with slow Wifi performance on Ultimate-N 6300 built-in card)

Work-around:
I had to modify /etc/init/nvidia-prime.conf (add 'exit' statement near the top) and cat /dev/null to /etc/X11/xorg.conf in order to get back to full desktop mode.

Please see attachment from out put of apport-cli -f -p nvidia-prime --save bug.apport

Cheers,
ak.
