I installed Red Hat Linux 7.1 on a brand new Compaq Proliant M370 server. Had a crash and had to reinstall. Set to autostart level 5. After the reinstall, system hangs at xserver start (gray screen, x mouse cursor), before gui login. Ctl-Alt-Bcksp kills xserver, restarts xserver and finally displays the gui login. From there I can login using root. I want to use Xconfigurator to see if I can fix the problem. However, when I switch to a console, I cannot login. No matter what user account I try, I get dropped back to a login prompt, with no error messages. MD5 and shadow passwords are enabled, but why would this be a password problem, when I can login from one interface, but not the other?
