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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1249067 Title: nvidia prime causes freeze at start up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1249067/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
