I have a problem with my newly installed ATI driver so my Fedora 12 boots to a frozen graphic mode display.

I need to force it to boot to text mode interface to start adjusting my X configuration. What to do?

This is a new Fedora 12 installation without any change to GRUB etc.

Thanks!

When you first start your computer, the GRUB screen (where you choose your Operating System) appears. Select the Fedora that you want to boot into, but press the a key instead of pressing Enter.

You will see a line somewhat like the following:

kernel /vmlinuz-2.6.9-1.667 ro root=LABEL=/ acpi=on rhgb quiet

Add the number of your runlevel to the end of that line, and then press Enter. For example, to boot into text-only mode, the line would look like:

kernel /vmlinuz-2.6.9-1.667 ro root=LABEL=/ acpi=on rhgb quiet 3

You will then boot into the new runlevel this time only.

Hold down Ctrl when booting to show the GRUB menu. Then select the kernel you care about, hit A, remove rhgb if it shows on the line, then go to the end and type Space3Enter.

I would accept your answer too but I can accept only one answer. Also I can't give you +1 because I am too poor. Thanks very much Mr rich :) –  mmonem Jul 13 '10 at 15:25

On newer versions, pressing A won't work any more - hit now "E" to enter edit mode. A multi-line configuration will appear, but there you will find again those same entries "rhgb" and "quiet", just remove them and put a 3 instead.

Then pressing F10 will take you to the (now usefully verbose) boot process, landing in a (text) login prompt. Done.

(Tested with Fedora 20).

The question, however, is about Fedora 12, as it says three times over. Fedora didn't switch to GRUB2, with the different keyboard commands, until Fedora 16. –  JdeBP Feb 14 at 4:25
