“signal out of range” when starting grub after Natty server installation

  • 772

I get “signal out of range” displayed on screen after boot up from fresh Ubuntu installation, if flashes grup in corner for half a sec then it goes to “No Input Signal”, anyone got a clue how to get the grub to load in diffrent resolution with out have access to the file system?

if not i guess my only option is to boot from the cd and edit som files to get grub to load in diffrent resolution?

as it is now i cant get access to grub menu, and i cant get access to login screen, all will give me “No Input Signal”, anyone worked around this?

ubuntu grub

  1. You could let the system come up and then access one of the text VTY's to make configuration changes. Wait until the system has finished booting and use CTRL-ALT-F1 to access the text console.

    If that still leaves your monitor showing No Input or similar, your only real option will be to boot from a LiveCD, mount the filesystem(s) on your machine and make the necessary configuration changes.
