I want to know what I can do to make gnome use less memory. After a new install it uses around 1100 Mb.
Less memory usage Gnome?
You need to provide more info about the packages that you are using.
ps_memhere, if you don’t have it, open a Terminal and install it with
sudo pacman -S ps_mem, type your password, type
sudo ps_memput your password, select the list and copy with Ctrl+Shift+C and paste here Ctrl+V.
It’s a list of packages and how much RAM each one is using.
GNOME probably uses something like 500-700 MiB RAM in most cases, after boot. If you want something lighter I recommend Antergos Xfce, it usually uses 350-400 MiB if you don’t add anything else, if you want something even lighter, Antergos Openbox uses 250-300 MiB the last time I checked, but I think you can use even less with it, but is not recommended for begginers.
All this confusion about RAM usage… what for is your RAM? to be used or not?
Only total: 5.70G RAM
On usual system usage i get: active used RAM: 2.93G
1,9G are used by Browser and email-client ;) (autostarted)
So keep in mind that real free RAM is not usefull
