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. ** Attachment added: "apport-cli -f -p nvidia-prime --save bug.apport" https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1249067/+attachment/3969441/+files/bug.apport -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-prime in Ubuntu. https://bugs.launchpad.net/bugs/1249067 Title: nvidia prime causes freeze at start up Status in “nvidia-prime” package in Ubuntu: Fix Released Bug description: I believe nvidia-prime modified my xorg.conf to use intel during boot. I had to remove xorg.conf to enable my system to boot to unity again. I've attached the file that caused the problem. My system has onboard intel graphics on the motherboard, and a beefcake nvidia card to which my monitors are connected.
