Xorg crash on first boot after apt upgrade

[Christian Kirbach]

I installed a daily snapshot of 18.10 in a VM.
After removing some unneccessary application, I ran

apt update
apt upgrade

and rebooted. I noticed X crashing after the reboot, taking me back to the login manager. I have the option selected to automatically login without password.
X did not crash when coming up the second time, tough.
