I am running Redhat 8.0 on my machine. I recently installed sawfish from the rpm but how do I configure it so that it shows up as one of the possible sessions in the login screen?

A GUI is made up of three layers of software. Sawfish is a middle layer, between X Window and Gnome. So sawfish cannot appear on the login screen. Instead, you activate sawfish by configuring gnome to use sawfish.

Ooooh. That makes sense. How would I go about configuring gnome to use sawfish?

I went looking through my gnome configuration menus for how to install sawfish. I found the panel to configure sawfish under Gnome menu-> Applications->Desktop pPreferences->Advanced->sawfish but I could not find any way to specify sawfish as the window manager versus, say enlightenment.

Then I checked my install notes from last December. When I upgraded from gnome 1 to gnome 2 the SuSE packages installed sawfish as the default window manager for gnome and I never changed it.

So I have to change my answer to: I don't know how to change the window manager in an already installed gnome.

Sorry about that.

It is possible that your Red Hat sawfish package set up sawfish as the default gnome window manager.
