Desktop install

Coming after a long time from ArchLinux, i like the crux principles (source, systemd-free). But actually, can't install xfce_4. 16 nor mate desktops : after a while of compilation, i'm already faced to "fatal" compilation errors. I would also install lightdm or gdm (or any other login manager), but do not find how do it. I do not like leaving this good distro.
