I have Ubuntu 12.10 x64 running in a VM in VirtualBox. I was writing some code, and then I minimized the VM window for a few seconds. I tried to open it back up, and it crashed (or had crashed sometime when it was minimized). When I restarted, X was no longer starting, but I was able to log in to terminal and access my file system.

I did just change my screen configuration today (from Gnome's "Displays" configuration window) to 2 screens instead of 1. It was working just fine for hours and then this happened.

Anyway, this is what I see with dmesg:

[   32.168521] Console: switching to colour frame buffer device 80x30
[   32.168532] fb0: VESA VGA frame buffer device
[   35.114612] init: lightdm main process (1014) terminated with status 1
[   50.270170] init: failsafe-x main process (1347) terminated with status 1

startx gives me this:

[   487.758] (==) No Layout section.  Using the first Screen section.
[   487.758] (==) No screen section available. Using defaults.
[   487.758] (**) |-->Screen "Default Screen Section" (0)
[   487.758] (**) |   |-->Monitor "<default monitor>"
[   487.758] (==) No monitor specified for screen "Default Screen Section".
        Using a default monitor configuration.
[   487.778] (EE) Screen(s) found, but none have a usable configuration.
[   487.778] 
Fatal server error:
[   487.778] no screens found
[   487.778] (EE)

sudo Xorg -configure gives me this:

(++) Using config file: "/home/xxx/xorg.conf.new"
(==) Using system config directory "/usr/share/X11/xorg.conf.d"
Number of created screens does not match number of detected devices.
  Configuration failed.

After checking the xorg.conf.new file, it shows 3 screens and 3 devices. I only have 2 monitors, though. I tried changing my VM configuration between 1 and 2 screens -- neither configuration worked. Not sure what else to try.

SOLVED. I uninstalled Guest Additions. Was able to start X after that. This is the command I used: sudo /opt/VBoxGuestAdditions-4.2.0/uninstall.sh –  ComtriS Sep 13 '13 at 3:44
This was exactly the issue I was facing: virtualbox.org/ticket/11709 –  ComtriS Sep 13 '13 at 5:02
If it's solved, please add an answer and accept that. This way, it will be easier to know that it was actually solved. –  Jo-Erlend Schinstad Sep 13 '13 at 7:16
I have to wait 8 hours to do that apparently -- very irritating. –  ComtriS Sep 13 '13 at 11:22
