Add me to the users for whom lightdm worked. gdm runs, appears and on shutdown (service gdm stop) appears to be doing some sort of a loop of the NVIDIA Persistence Daemon... the daemon leaves a screen message that is hidden until the stop breaks in on it.

Reinstalling NVIDA, GDM, Installing intel micro-code and repeated restarts/resets did not get past this last step on the screen Sep 3 08:13:42 occam systemd[1]: Starting User Manager for UID 118... Sep 3 08:13:42 occam systemd[1]: Started Session c1 of user gdm. This is by observation the last step prior to presenting the gdm user menus. I am including the kernel log for the machine. This doesn't clearly identify the problem but it does show several logs that cannot be created. I have the lightdm working and am loath to break it all again to collect those logs but I am going to create them and make them writable. The gdm issue seems not to be An older NVIDIA card had no problem but hadn't had the NVIDIA drivers installed. The new card is a 1060. The GDM process IS running there. ** Attachment added: "kernel-log-redshift-2016-09-03 contains fails with gdm and successes with lightdm .
