I'm trying to use gdm on a very basic system using components compiled separately, "linux from scratch" style 
using the 3.10.x version of the various gnome components.

Although gdm starts, it does not start properly - there's no top panel, side panel, etc.

Is there any documentation available that explains how to use gdm on a basic system:

What is required in .xsession?
What is required in terms of linux-pam/polkit rules?

Although I have debug enabled, all I get at the moment is:

gdm[15620]: Enabling debugging
gdm[15620]: Changing user:group to tc:staff
gdm[15620]: Failed to create ran once marker dir /var/run/gdm: Operation not permitted
gdm[15620]: GLib: GError set over the top of a previous GError or uninitialized memory.
This indicates a bug in someone's code. You must ensure an error is NULL before it's set.
The overwriting error message was: Operation not permitted
gdm[15620]: Failed to create LogDir /var/log/gdm: Operation not permitted
gdm[15620]: Only the root user can run GDM
i'm sure it means what it says. directory permissions. and it depends what user you are when starting gdm
gdm binary error that root is req. also gdm has changed it's policy on what user starts gdm and what user gdm is while running. if you don't know what that mean you have a lot of learning curve to catch up on. 

i suggest looking at www.tldp.org for help.
your not using a "linux distro". gdm expects something like directory existence and permission was taken care of.

i'm not suggesting you use it instead of gdm. i mention it because it creates directories and sets permissions when installing (it's more like kdm but maybe more advanced). it has a table of startup sequence (when each script is called during X startup)
** my point in all this. is you don't necessarily have that setup with gdm or ANY program if you take them off www.gnu.org or wherever: you have to do it. you are in effect "creating a pkg" for a new distro were you to save your work as isntall scripts. ** 

that is what "from scratch" means i'm sure.

Hi, try to set up the gdm dir to be owned by the user gdm is run as.
Usually you have a gdm user.



gdm[15620]: GLib: GError set over the top of a previous GError or
uninitialized memory.

Same here, seems a permissions problem.



gdm[15620]: Only the root user can run GDM



For the rest i have no idea.

Hi, try to set up the gdm dir to be owned by the user gdm is run as. Usually you have a gdm user.


This system has only three combinations of user/group:
tc:staff, root:staff and root:root
gdm was compiled with switches to set the user:group to tc:staff

In fact this error occurs even when gdm is started as root, which perhaps indicates something is needed in 
terms of linux-pam/polkit rules for gdm, but if so, what?

You can try to see if something on our project can help you. We do build
gdm for slackware and there is also a pam file for it.
See here:
