Linux Emergency: entering Single User Mode in fedora

So I installed ati driver on Fedora, BAD IDEA. Because, once you finish booting, you cannot even call virtual console like alt-f2.

Solution is to access Single User Mode. Then run the uninstall script.

Actually single usermode is not limited to this, it is meant to be used for some of the worst case emergency.

To go to single user mode
Once rebooted,
1) Go to grub menu
2) Select the option to boot into linux
3) Press a
4) it should shows something like this

kernel /vmlinuz-2.6.29.4-167 ro root=LABEL=/ acpi=on rhgb quiet

Just add "1" behind it

kernel /vmlinuz-2.6.29.4-167 ro root=LABEL=/ acpi=on rhgb quiet 1

5) Press enter

You should be able to access the shell as root without login. Now you can do anything to fix your problem.

This is dangerous,because you can access everything, yes everything. Enjoy!!!
