Upgrade from 10.04 to 11.04 gives error on monitor

[melmerby]

Hi all
I have just upgraded from 10.04 to 11.04 (via 10.10 on the way!) and I have lost my GRUB screen.
After the BIOS screen all my monitor does is display the error "Signal out of range"
GRUB is still there hiding and I can select Windows or Kubuntu by holding down the up or down arrow keys. Everything else seems OK.

Any ideas?

Thanks
Keith

So you are able to select (K)Ubuntu and log in?

Then you could install Startup Manager and change the properties of the start up screen to something your video card does accept..

That means the monitor is not being detected by the graphics card. There may be a Grub boot menu, but you'll never see it until you enter the needed video (or ACPI) boot option, so the monitor doesn't go to sleep immediately upon booting.

Yes, once I have used the up/down arrow keys (blind!) I can log in to either Kubuntu or Windows as required. I just can't see the GRUB screen.

The video card (nVidia) will accept pretty well anything (it is fairly modern) from VGA up to high def resolutions and the monitor is 1280x1024@75Hz, so what could Kubuntu be producing that it doesn't like?

Post the contents of your /etc/default/grub file please.

Nothing strange in your /etc/default/grub file. You can edit it as root and modify the following line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Remove the quiet splash so the line looks like:

GRUB_CMDLINE_LINUX_DEFAULT=""

Save and close the file, then at a command line type:

sudo update-grub

Reboot your PC and report back.

OK
I have done that and there is no change to the startup.

I know it's sometime since I last posted by it might be of interest to some.

I have now changed my graphics card from nVidia to AMD Radeon which of course meant installing different Windows drivers. (the nVidia drivers had been updated several times without changing the problem)
The GRUB screen has re-appeared (in colour as well) and so far everything seems OK!
