All back to normal running nVidia drivers. For 14.04 ignore advice about /etc/X11/xorg.conf. Irrelevant. Instead, boot into recovery mode in the grub menu.
Go into a shell (root shell) from the grub recovery menu. # make read-write mount -o remount,rw / # remove nvidia packages. apt-get purge 'nvidia*' exit The apt-get command needs the quotes around nvidia*. You will get a warnng that the first reboot might not be enough. I had to boot twice. Now in the Settings->Addtional Drivers select the nvidia driver you want. Then sudo apt-get install nvidia-modprobe Now reboot and all will, I hope, be good for you too.

First encountered when booting 3.13.0-63-generic #103-Ubuntu on restart after upgrade from 3.13.0-62. that crashes the same way during boot. I tried using grub and booted into 3.13.0-62 but that behaved the same. The data that should be here System remounts disk readonly and boots. I can ssh in to the system (but being read only cannot change anything). Ran memory test overnight (about 1.5 complete cycles of the test) and no errors. (on the --63) uname -a Linux Dseti3.home 3.13.0-63-generic #103-Ubuntu SMP Fri Aug 14 21:42:59 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Two nVidia GTX 760 GPUs. Using nVidia drivers because using OpenCL for boinc Seti@home and Einstein@home. I removed one GPU (as a test) and reboot encountered the same problem. Suggestions as to how to figure out what is wrong would be most welcome.
