what does the command source /etc/profile do?
I'm getting through my problems with configuring xorg. right now I have to run this command before I can test X with "X" or "startx" I know this problem is just me not really understanding what is going on. Can anyone enlighten me?
Thanks~

As the Handbook says, it sources (pulls in) the global profile.
Why ?
Well, many emerges change the profile, and normally it is only pulled in once, when you log in.
So yes, you could also log out and then log back in.
If you think it's more convenient.

| profile is a shell script. Shell scripts run in their own private environment eg variables only exist for the script. Source applies changes to the current shell/environment eg variables will be inherited by the current shell. |

logging out and rebooting haven't changed anything. What am I doing wrong? I can only run X if I run source first. I'm still working through tweaking xorg.conf, so it isn't really a problem right now, but I know I'm just not doing this right.

| Sorry to paraphrase but what you mean is you can only run xorg if you run /etc/profile first and keep the settings after the script ends. If you change your .profile to include whatever xorg needs in /etc/profile then you shouldn't need to run /etc/profile again after you've logged in (same environment). However, I didn't have to alter with my login script to do any of this so maybe this is just symptomatic of something else wrong. What variables do you think xorg needs - export something DISPLAY:0? |

You could always add "source /etc/profile" as the last line of your ~/.bashrc, which forces /etc/profile to be sourced whenever you start a bash session.

With X ? Hmm.. could be any of about a gazillion things 
Really.
But first things first - getting it to run at all.
What is in your PATH after you have logged in?
If /usr/X11R6/bin (or /usr/bin/X11) is not in there, you can't "run" it as a system command.
This is normally put in the profile by the X install, which is why you have to do the source bit in the first place: any changes to the profile will only take effect after you source it or after you re-login.

Then compare the PATHs before and after you source the profile - that will at least tell you if that's the problem.
