I was trying to follow this link to edit the xsession file to start fluxbox, however I could not find xsession file:

please tell me where to find the xsession file. thanksI'm assuming it's in Debian's ARM repos, if it's not you might need to compile it.
After that, edit the ".xsession" file in your home folder (/root if you're logged in as root (which isn't a good idea usually) or /home/<username> otherwise). You might need to create it if it dosen't exist. Make a copy of it if it does exist, so you can switch back to LXDE easily. If the text "lxde-session" appears in the file, replace it with "fluxbox". Otherwise, add "fluxbox" to the end of the file.
After that, just start up X as usual, it should start up in Fluxbox.
