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?

Boot from the live cd and open a terminal. Assuming your root is on /dev/sda1, then do this:

sudo -s

mount -t ext4 /dev/sda1 /mnt

gedit /mnt/etc/default/grub

for f in sys proc dev ; do mount --bind /$f /mnt/$f ; done

chroot /mnt

update-grub

When the editor comes up, uncomment ( remove the '#' ) this line and save and exit:

#GRUB_TERMINAL=console

After the update-grub, reboot and you should be good.
