I installed a fresh Antergos Xfce a few days ago because I was tired of GNOME and wanted something lighter. But after installing I’ve noticed there were several GNOME packages already preinstalled. After I removed a few of them(wich ended up removing all of GNOME packages because of dependencies), everything broke, the Whisker Menu, the Plank, I couldn’t end the session, I had to reboot, after reboot display manager broke either and I couldn’t login.
So… if one wishes just to use just Xfce you are forced to use GNOME packages. I’m not using Antergos anymore because of these critical issues, I’m using another distro… Also I think I’ve had enough with Arch based distros for now… I wiped the whole thing and I’m using Debian Xfce now.
