My computer boots to a black screen, what options do I have to fix it?

I installed Lucid Lynx over PXE onto this dell server seemingly successfully, but booting from the HD results in a black, unpowered screen. There appears to be no network connectivity to the box either. It may have landed at a textual busybox type prompt, but I can't see it. Ctrl-Alt-Delete seems to reboot.

On my last attempt I held shift and the grub menu came up, but recovery mode produced the same results.

Should I drop into the grub prompt and give the kernel a magical boot option? Should I boot from a rescue cd and munge some bits on the HD? Give up and install windows?

  • Have you removed the quiet option from grubs kernel commandline? If not, try to boot without quiet and splash. You'll see some output.

    Could you change your subject to something like 'Lucid Lynx ..'. When I read lynx I'm thinking of the application lynx and not Ubuntu 10.04.

Here are a couple of "magical boot options" to try:

  • nomodeset
  • i915.modeset=0 xforcevesa

I'd remove quiet splash when trying these and only one at a time, not together as they'll likely conflict.


Edit: for an explanation of how to use these:

  • When booting, hold left-Shift
  • Highlight the first option and press e
  • Go down to the line that looks like:

    /boot/vmlinuz-3.0.blah-generic root=UUID=blah ro quiet splash
    
  • Replace quite splash with your boot option of choice.

If that works out well, you can make the changes to /etc/default/grub by editing the GRUB_CMDLINE_LINUX_DEFAULT value. After saving, run sudo update-grub.

  • thank you for your options. before I saw your answer I used the ubuntu pxe rescue to install nvidia-latest, which eventually resolved my issue. Dell Precision T3500
