There are a few ways. If you have access to the physical system and can log in, then, from a terminal session/console, you can type "init 3". To boot, Grub will present you with a couple of options, on of which is an option to edit boot/kernel options (I think it's "a"). At the end of the kernel/boot line, type "1" or "single" to boot into single user mode, or "3" to boot to runlevel 3. I would submit, though, that most of what runs in runlevel 5 will usually also be started in runlevel 3, so you might be better off bringing the system up in runlevel 1 (single user mode), first, then, after you've fixed what you need to, issue "init 5" to bring the system up into runlevel 5. -- Mike Burger http://www.bubbanfriends.org Visit the Dog Pound II BBS telnet://dogpound2.citadel.org or http://dogpound2.citadel.org To be notified of updates to the web site, visit: https://www.bubbanfriends.org/mailman/listinfo/site-update or send a blank email message to: site-update-subscribe@xxxxxxxxxxxxxxxxx -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
