After a power failure, on re-starting UBUNTU linix, get message: "gdm server auth dir (daemon/ServAuthDir) is set to /var/lib/gdm but it dosen't exist". the directory IS there, but it doesn't start volume manager properly, complains HALD is not running and stops at a single command line. I have been trying to find out how to fix this for many months. can long-in as single user and startx , but no volumes apart from hard disks are found. Familiar with UNIX but not as good on LINIX. any help would be appreciated.

After months of not knowing how to fix this I looked at the web-page:

which gave a lot of advice, and I had already set chmod 755 for the directory /var/lib/gdm... and associated files.

(use: ls -lsa to list all the files starting .(dot) ).

I looked through the notes to try various things, but starting the gnome ONCE from a bash as root.

sudo gdm start 

seems to mean it is now always started at each boot.

So that seems to have fixed it. (There are quite a few other websites requesting a solution, this seems to make the files needed) and it creates file .gdminfo which I think it was looking for.
