I am getting my LFS/BLFS system setup and I am planning on installing fvwm as my window manager. However I would like to have graphical login since this is going to be my desktop system. What are my options out there for use with this? I saw KDM, GDM, XDM, SLiM and Entrance but I'm not sure which one would be better or which one would best suit me. I would like one that I could customize the look of to match my fvwm set. What other ideas do you have?

GDM is the GNOME display manager and requires some GNOME libraries. KDM is the KDE display manager, but I don't use KDE so I'm going on memory that KDM is provided by kdeBase. kdeBase requires kdeLibs, so you basically have to install a base KDE to use KDM. Entrance is the Enlightenment DE display manager and requires some Enlightenment libraries.

SLiM is desktop environment independent and XDM is the default X Windows display manager. You don't need to install XDM if you use one of the modular Xorg releases. If I were going to use fvwm (and I used a display manager), I would use SLiM because of the integration of the other DM's with a particular DE. SLiM is more customizable through themes than XDM which meets your customization requirement.

I can't think of any other display managers; popular ones at least. The only other idea I would have is to just boot to run level 3 and start your X Windows from the CLI. Of course I only recommend that because that's what I do .

I think SLiM would be the best choice. It isn't the easiest to make themes for, but if you can make them for FVWM, then it shouldn't be hard to learn.

Well thank you. Now to actually get it working...
