And I just remembered that I have some logs from the newer failure that might help. I will post short excerpts here as otherwise there is nothing to distinguish them from the logs of the older failure.

It is just a record of the fact that I changed the settings around some as I tried to get something to work. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1482711 Title: X displays nothing instead of login screen Status in linux package in Ubuntu: Confirmed Bug description: The kernel version in the auto-generated information is wrong, because when using the kernel with the problem, I can't do anything, including send bug reports. This happened with the newest kernel update to 3.13.0-61. I am using -59, which still works, to send the report. Since this is at least possibly graphics related bug I should also state that the update automatically changed the nvidia driver from 331-updates to 340-updates, however Nvidia's page for the 340 driver does not include my graphics card (GeForce 610M).
