i get out of X and it says i need to be in X what do i do?

thanx in advance

I'm assuming it compiled correctly as you didn't mention errors. did you try to log out of your window session and log back in. See if it shows up in the session menu when trying to log back in.

Do you boot to runlevel 3 or 5? If you boot to 3 then you simply edit or create the .xinitrc file in your home directory. The contents of the .xinitrc file should be:

exec /path/to/fluxbox

Then when you log out and startx again you will be thrown into fluxbox.

I don't have a xinitrc anywhere i use redhat 9 and gnome as of now.
