I just updated my arch linux to gnome 3.22 and it broke many things. Most annoying is that gnome-terminal won't start. I checked journalctl and found that :
oct. 18 15:11:05 jarvis dbus-daemon[727]: Successfully activated service 'org.gnome.Terminal'

Going on and on on different libc.so.6 calls.
I can't find how to fix this. Does any one have an idea of what happened ? and of what I should do ?
Try switch login screen to use Xorg,
edit file: /etc/gdm/custom.conf and uncomment WaylandEnable=false:
[daemon]
# Uncoment the line below to force the login screen to use Xorg
# WaylandEnable=false
