If you want to get good old 80×25 console in text mode of Fedora, you need to pass “nomodeset” option to the kernel.

Open the file /etc/grub.conf or /boot/grub/grub.conf file and “nomodeset” option to the “kernel” line of the active boot entry.

kernel /vmlinuz-2.6.28.24 ro root=/dev/sda2 rhgb quiet nomodeset
