Dear Guix,
I am using herbstluftwm as my window manager on my old Guix laptop. It shows up as an option in a bottom right corner of GDM. On my new laptop, this menu doesn't show up. In both cases I have included herbstluftwm as a required package in my config.scm file. My old laptop's config.scm makes no mention of herbstluftwm in the configuration anywhere else than in bringing in the package. However, I further know that this package does create an xsession output to a herbstluftwm.desktop file under /gnu/store. Does anyone have any ideas what the missing incantation is to make herbstluftwm (or any other relatively niche window manager with a .desktop file) show up on the GDM menu? Thanks, Kyle
