I have some changes that are more-or-less ready. It’s mostly just cleaning up, but it makes it so that GNOME does not have to be in the system profile for GDM to work. (Note that the GDM service references GNOME Shell, which requires most of GNOME, but it doesn’t end up in the profile.) I spent some time trying to get “libgdm” split out from GDM, but GNOME Shell kept getting killed with SIGTRAP. This happens during the execution of JavaScript code, and the recommended way to get a backtrace did not work, so I’m stuck there. I will try and send patches in the next day or two. > The one thing I didn’t get to work is ~/.xsession support. Any ideas? Digging around in the source code, there’s a comment that says that the distributed “Xsession” script should run “~/.xsession” if passed the special keyword “custom”. However, looking at the actual script suggests that this comment is mistaken. (If it did work, you might be able to make a “custom.desktop” file with “Exec=custom” that would trigger the right behaviour. I did not test this.) Debian provides a custom “Xsession” script and a custom “default.desktop” file, which runs the script with the special argument “default”. With this argument, the “Xsession” does a bunch of stuff by running all of the scripts in an “Xsession.d” directory, including one that tries running “~/.xsession”. In short, it looks like we have to either fix or customize the “Xsession” script. Making the script work like the comment suggests and using “custom.desktop” is probably the simplest thing to do. > I’d real like to get that fixed and then we can finally replace SLiM > with GDM as the default. > > BTW, at the Guix Days, there were discussions about defaulting to > LightDM instead of GDM.

Of course, it is good to have a nice alternative to SLiM that is simpler than GDM. GDM is needed for the proper GNOME experience, but it is too much for most non-GNOME setups. Ultimately, Guix is nice and configurable, so I’m everyone can find a way to be happy. :) -- Tim
