You're right, after deleting the xorg.conf I could start my system two 
times (with poor resolution), but after these two times, I couldn't 
bring up the system the last 10 tries anymore.
Before the todays update I could start it with "init 2" from recovery 
mode. Now I can't start my system anymore.

I deleted most logfiles including XOrg, GDM3-directory, ... and after 
the reboot I had only some empty log files:

But I've found an error message in the syslog.1
I think this is not an gdm3-bug its an kernel bug.

Nov 29 18:04:09 venus kernel: [   23.356256] BUG: unable to handle 
kernel NULL pointer dereference at (null)

I've attached the syslog. Can you confirm this?
Can you move the bug to the correct module? Or should I create a new 
one? Which is the correct module?
I'm new in this process ... Tell me, if you need more information.
