[CentOS] Error running startx as non-root user

I've been looking online for resources that may help me, but I haven't found anything that worked. I'm trying to run x as a non-root user. Any suggestions?

I get the messages:

Fatal server error:

PAM authentication failed, cannot start X server.

Perhaps you do not have console ownership?

Please consult the The X.Org Foundation support

for help.

Here is what I've tried:

1) chmod 777 /dev/console

2) /etc/pam.d/xserver looks like:

auth sufficient pam_rootok.so

auth required pam_console.so

account required pam_permit.so

auth required /lib/security/pam_console.so

auth required /lib/security/pam_permit.so

account required /lib/security/pam_permit.so
