Input out of range error when trying to install

swim4food · #1 19th January 2013, 02:09 AM

I am trying to install Fedora 18 on my server which is a dual core opteron system with a gig of ram and on board video. When I boot. I see "starting grub" then monitor reports that the signal is out of range. If I try to boot from a live disk, it goes out of range. What do I do? I've googled around and seen lots of people saying to change different config files but how? Also what is the right thing to do in what config file? The on board graphics is only VGA as an FYI and the monitor in a LG Flatron L1710S.

Thanks so much!

Perhaps try another distro's Live CD and see if you get the same issue?

I tried Ubuntu and had the same issue.

Any ideas on how to solve this? Do I need a new graphics card or what?

You probably hit the glitch where grub2 tries to set a video mode not supported by your hardware. VESA modea above 1280x1024 are not in the standards, and is supported differently on different hardware. Grub2 (in my opinion) should never try to set a mode greater than what is in the standards.

What you can try.

Just let your machine boot. When it loads your video drivers, it your display should come back up and you can see things.

When it boots, then go to a terminal screen and sign in as root user.

Edit your /etc/default/grub file and add the following lines (or change if the lines already exist)

Code:

GRUB_GFXMODE = 1280x1024x32
GRUB_GFXPAYLOAD = keep
GRUB+GFXPAYLOAD_LINUX = 1280x1024x32

save your changes, then run

Code:

grub2-mkconfig -o /boot/grub2/grub.cfg

That should have things set where you will see your display when grub2 comes up

Edit:
To sign into a terminal as root user, open a terminal window and do this:

Code:

su -
(root password)

It never comes back so I can't see anything. In addition, it is in essence a clean hard drive so how would I change a config file when I have no install?

OOooopsie!

I missed seeing where you are trying to install. I was thinking you hit the bug that happens after you install. Dang it.. I need to start wearing my glasses more often

It's kinda hard to edit the kernel line since you can't see anything, so changing the video mode there isn't going to help much, either

Ok so is there any way to solve this that you can think of?

I had similar problems with a via pico itx system. Try to install fedora from usb and unable as mode not supported.

I tried to install fedora 18 by appending text to the grub boot menu and that didn't seem to work either,
as the system wouldn't boot. It never gave an option to set the root password or setup another user.

If someone could advise the correct way to install via text option I would appreciate it (fedora 18)

As a workaround I simply installed fedora on another intel system then swapped the drive back to the via system.
