I've done a lot of searching on this, typically this is a problem I could resolve myself but has baffled me all of a sudden. I believe I installed Gware for Slackware 12.1. I have a nice Gnome Desktop (in which if you would like to gander im posting it on Linux packages with my other desktop screenshots) but I use other window managers all the time. I have E17 installed, Ice-WM etc etc. GDM somehow when I select Enlightenment launches fluxbox instead. I've looked in /etc/X11/gdm/Xsessions and commented out the ones I don't need and added my own. I also went back to runlevel 3 and ran xwmconfig to see if anything was wrong there but everything launched fine. I guess my main question is what file is controlling my display of sessions? I thought it was /etc/X11/gdm/Xsessions but changing this does nothing. I didn't restart GDM by itself so I just rebooted the whole thing. Does anyone know where this mystery file exists?

Look around /etc/X11/xinit/ and see if there are any poorly linked files or perhaps a stray line in the xinitrc.<wm> file.

Everything seems fine xinitrc, in /etc/X11/init was symlinked to xinitrc.fluxbox but I removed that and now it just drops me to a failsafe unless I choose gnome. I still need to be able to edit my sessions list anyone up for it?

I fixed it. in /etc/X11/gdm there is custom.conf. There was a line like such

It had some other directories in it and was commented out, still doesn't solve where the choices were coming from in the first place but this will fix it.
