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): enter image description here

What to do?

  • Have you tried tty1 and startx? – Novine Nov 6 '13 at 20:12
  • It gave me a bunch of errors that I kind of understood! :D There was a parse error in /etc/X11/xorg.conf. And modified that file not too long ago, trying to configure touchégg correctly. I will look into this and will return when I've got things sorted out. – lindhe Nov 6 '13 at 20:26
  • Yup. I deleted everything (which was the touchégg configs) from the xorg.conf file, and now everything is working great. Thank you! :) – lindhe Nov 6 '13 at 20:34
  • I'm so glad I could help. If you have more problems you can come to me :) – Novine Nov 8 '13 at 20:02

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.

Novine's comment on my question indirectly gave me the answer. When I booted into recovery mode, went on by "resume normal boot" and then logged in via tty1 I ran startx. This gave me an error saying there was a parse error in /etc/X11/xorg.conf. I then opened up that file and emptied that file from some unnecessary lines I had put in there a short while ago (I saved it all empty).

That made the trick, and everything is now working great! Big thanks to Novine! :)
