I went to login and got these two messages

(1) Your home directory is listed as: '/home/iridium/ but it does not appear to exist. Do you want to login with the / (root) directoryas your
home directory ? it is unlikely anything will work unless you use a failsafe session.

NETXT MESSAGE (2)

Users$home/.dmrc file is being ignored this prevents the deflaut session
and language from being saved , file should be owned by user and have 644 permissions , users $home directory must be owned by user and not writable by others users.

SYS + REBOOT could not update ICE AUTHORITY File/.iceauthority.

Does anybody have any Idea how to fix this. I can put my username in and password in but thats it.

Yes...you log in as root, and re-create your user ID and/or home directory, or you restore your home directory from backups. It would seem that either the location for your home directory is unmounted (such as /home being on its own partition), or that it's been deleted.

If it's deleted:

• Log in as root/another user, and restore from backups
• Log in as root, create the directory manually with the mkdir command, then do a chown on it, to make it owned by your user ID.

If it's unmounted:

• Mount it manually (look at your /etc/fstab for the location, and use the mount command)
• Reboot, and it will probably mount itself.

Also, please use a more descriptive subject header than "Major problem need help"...that doesn't tell anyone, ANYTHING about the issue.

Ask your sys-admin for help. You cannot solve this by yourself.

thanks for you're answers but I have no Idea where to start. I need someone who can help me
step by step

You start by following the instructions/suggestions given to you already. You don't say anything about what version/distro of Linux, if this was ever working, or what you changed to cause this problem, so there's little we can tell you to do, besides what's already been posted, which is essentially the 'step-by-step' directions you asked for. Need further instructions? Then type in:

• man chmod
• man mkdir
• man mount

There's not much more to it, and it can't be made more simple. Either create your home directory (which is missing), restore it from backups (which you don't say if you have or not, and if you do..what you made the backups WITH), or reboot your system to remount the /home partition.
