No network in Gnome

I think I 'successfully' completed a Gentoo installation from the minimal_CD followed by the installation of the Gnome environment. But I have serveral problems. One of them is the network.

The computer is connected to network via cable over enp2s0 (eth0). In Gnome environment I have no network even NetworkManger reports the network is connected and shows a correct IP address, ...

If I boot in "recovery mode" , I have no network as well, but with the following command I can manage to establish a working connection:

ifconfig -a
dhcpcd enp2s0

How can I get a working connection in Gnome?

Please note one of the other problem I have, it is that Terminal app in Gnome is not working at all. The only way I have to access the terminal is via the recovery_mode.

Dhcpcd does not work well with NM.
Plz disable and stop dhcpcd and run

First of all the easy question: the Terminal in Gnome. I simply double click on the icon and then nothing happen. I even re-emerged gnome-terminal, but no improvement.

Concernig the network, Shall I have to stop or disable dhcpcd? So systemctl stop dhcpcd or systemctl disable dhcpcd?

I will have a try but I'm not expecting any better, since at the first reboot after minimal installation (before installing gnome, just blackscreen and command line) I was without any network and I had to start and enable dhcpcd.

The only way to access a command line is via the recovery mode. I stop dhcpcd with systemctl stop dhcpcd and then systemctl disable dhcpcd.

Then I typed the command nmcli con show, but I have the error message "Impossible to create the object NMClient"

Typing the command systemctl list-unit-files | grep enabled I have:

NetworkManager-dispatcher.service enabled disabled
NetworkManager-wait-online.services enabled disabled
NetworkManager.service enabled disabled

Network problem

successfully enter command systemctl start NerworkManager

nmcli con show return an ethernet connection on enp2s0

nmcli con del <all-connections> return a 'syntax error near unexpected token 'newline' '

nmcli con add type ethernet autoconnect yes con-name eth0 ifname enp2s0 returns 'Connection 'eth0' ... successfully made'

nmcli con up eth0 return error 'Connection activation failed: No suitable device found for this connection (device enp2s0 not available becuase profile is not compatible with device (mismatching interface name)).'

No Terminal in Gnome

Changed /etc/locale.gen. Just: en_US ISO -8859-1 and en_US.UTF-8 UTF 8 are without #
regenerated the locales with locale-gen
made sure the selection is correct with eselect locale list and eselect locale set. Locale is set to en_US

No improvement from Gnome Terminal. it try to open but it fail to open the windows.

At the end network is working. The system is configured with systemd, so I stopped/disabled the network services of systemd.

systemctl stop systemd-networkd.service
systemctl disable systemd-networkd.service
systemctl stop systemd-networkd-wait-online.service
systemctl disable systemd-networkd-wait-online.service

Then I start and enabled NetworkManager.

This way it works. Probably there was a conflict among all the services.

Sorting out the issue I created a new one. now NetworkManager can create a connection in Gnome, but I do not have anymore connection in recovery mode, which is the only way I have to access the terminal.
