@fernandomaroto said in How to change desktop from Gnome to Xfce:
i’m not sure how many packages Antergos uses but belongs to gnome, so removing gnome could remove some Antergos packages.
@joekamprad said in How to change desktop from Gnome to Xfce:
True that may uninstalling gnome will uninstall also some packages xfce will need…
But you can simple reinstall via the same command to instal xfce in the first… but better before reboot ;-)
@joekamprad said in How to change desktop from Gnome to Xfce:
the package group “gnome” is from origin ArhLinux, while Antergos installs a different packagelist for the gnome-Desktop.
You should do a:
sudo pacman -Runs gnome-extra
or you do it with the help of pamac go to “groups” and check “gnome” “gnome-extra” “gnome-shell-extensions” from left menue it will listen all packages from this group… uninstall all packages from this groups…
Thanks @joekamprad for getting back to me with your suggestion above.
Because both @fernandomaroto and yourself warned me that “removing gnome could remove some Antergos packages” I decided to check the three groups you mentioned “gnome” “gnome-extra” “gnome-shell-extensions”
I compared the packages listed in each group with my other laptop on which I installed standard “antergos-17.1 Xfce”
and have listed which ones that are used by the Xfce install so I won’t uninstall those, here is the list in case someone else want to do the same…
Group used
gnome Xfce?
adwaita-icon-theme YES
evince YES
gnome-keyring YES
gnome-session NO
gnome-settings-daemon NO
gnome-shell NO
gnome-shell-extensions NO
gnome-themes-standard NO
grilo-plugins NO
gtk3-print-backends NO
gvfs YES
mutter NO
nautilus NO
tracker NO
gnome-extra Xfce?
brasero NO
file-roller YES
gedit NO
gnome-calendar NO
gnome-documents NO
gnome-logs NO
gnome-maps NO
gnome-music NO
gnome-photos NO
gnome-sound-recorder NO
gnome-tweak-tool NO
gnome-weather NO
nautilus-sendto NO
orca NO
seahorse NO
gnome-shell-extensions Xfce?
gnome-shell-extension-dash-to-dock NO
So I will uninstall the packages that are only used exclusively by Gnome.
Thanks to you both for helping me on this, much appreciated. I did learn a bit more about packages and package groups along the way 
EDIT: I opened package manager to remove the packages, and first chose the gnome group and selected 10 packages as listed above, but when I clicked Apply, I got a Transaction Summary with a list of packages which included xfce4-settings even though I hadn’t selected that package. So I canceled the transaction, as this package is used on my other laptop which already has Antergos Xfce.

I’m not sure how to proceed so wondered if you can advise. Still have a lot to learn about packages and package groups
I’m afraid.
Thanks again.
