13.10gnomexorg

I made a regular update using update center yesterday on My Samsung NP730U3E with Ubuntu gnome 13.10 and today it won't start. Or rather: it just gives me a black screen. On start up I get to enter my encryption password and everything seems fine. But after the encryption password is accepted it just blanks out.

When I boot into recovery mode and try to boot failsafeX it returns "Fatal server error: (EE) no screens found (EE)"

After booting into recovery mode and "Resume normal boot" I get to the tty1 prompt. If I head over to "tty7", where the graphical things usually are going on I just see this (and it's frozen):

What to do?

• I had same problem today on Lenovo P50. The issue was that I switching to nvidia driver from stock open source driver. The display would go black when I boot and login gets stuck in loop when I go to recovery mode. When doing Ctrl+Alt+F1 and trying to startx I saw errors such as screen not found. The solution was simply to roll back to stock drives using this command line:

sudo apt-get remove --purge nvidia-*


Voila! I'm back in but then xorg reported some error. So I did,

sudo apt-get install --reinstall ubuntu-desktop


Now there are no issues.
