Using dualboot Ubuntu/Windows desktop.

A black screen which appear after loading up the "Ubuntu" symbol. Then the screen prompted "No Input, entering sleeping mode". I wait for several minutes and no response. I reboot and got the same result.

Pressing the down arrow key show a flashing cursor on black screen.

The screen go black after this splash screen.

The screen goes black after this splash screen.

=========================================================

What I did today to the system:

  • Install a zsnes via apt-get
  • Tried to install fceux with this tutorial, but it didn't work
  • Boot up Windows and played with it for a while.

What I tried after Ubuntu failed to load:

  • Went to recovery mode, select the "DPKG package recovery" option, yes all the way. It did removed some packages. After reboot, the problem returned.
  • Tried to boot up windows and no problem. So most likely this is not hardware problem.

Any easy way to fix this?

  • Welcome to askubuntu! I'm having difficulty understanding much more than black screen at boot. Please try to add clarity to your question. Did you try searching for an answer prior to posting this question?

It seems the problem is the lightdm interface.

I followed this article and installed gdm then booted into Ubuntu successfully : http://www.webupd8.org/2013/01/ubuntu-lightdm-black-screen-when-using.html

sudo apt-get install gdm

Then I switched the default interface to gdm instead of lightdm when it asked. After that the problem was avoided.

Then I tried to reinstall lightdm:

sudo apt-get install --reinstall lightdm
sudo dpkg-configure lightdm

Then I reboot the PC and it works fine and I can log in successfully with lightdm

The splash kernel option might cause LCD monitors to enter sleep mode during the boot process when using DVI input.

In the grub menu, select the entry for Ubuntu and press e to edit it, then remove the splash option from the kernel line and boot.

If this solves your problem, you can make the change permanent by editing /etc/defaults/grub and removing the splash option from GRUB_CMDLINE_LINUX_DEFAULT.

On boot, press E (this puts you in edit mode) use arrow keys to move cursor to the line that says quiet splash. Backspace the "quiet splash" type in no mode set (then press F10 key) the screen will be blank when you hear the drive go quiet press Space bar.
