I just installed Slackware 9.0 on a new copmuter, everything was going great until I installed Dropline. After I rebooted I can't login as anyone,
I have no access to this computer at all , I can't login in as any user that I have created or as Root. Can anyone help.

Plop in your Slack CD, get to the prompt where you'd normally type "setup" and instead mount up your partitions in the /mnt directory. Then edit /etc/passwd to remove the "x" near root's login:
root:x:0:0::/root:/bin/bash

Delete that out, reboot, and root should have NO password, simply login as root, hit enter, and set a new password with:
passwd

Dropline really jacked me up as well, I ended up doing what nobody every should and reinstalled because of all the problems it caused me... course it was a while ago, I'm still bitter...

Cool

thanks I'll give that a try tonight.
