so here is the howto direct from fluxbox
How do I add fluxbox to my sessions menu in Fedora.
The fedora distribution uses a different setup again. Instead of the dm-specific locations, it requires session files to be in /etc/X11/dm/Sessions.
So, to get Fluxbox into its session menu, create the file: /etc/X11/dm/Sessions/fluxbox with contents:
[Desktop Entry]
Encoding=UTF-8
Name=Fluxbox
Type=Application
Icon=
Exec=fluxbox
You may need to put the full path to fluxbox in the Exec line if it is in a non-standard location.
This is a barebones entry. Hopefully one day we will be able to make a version with translations available in the main source distribution.
