I got a hold of Blackbox because I felt like GNOME was eating up too much RAM.

The problem is, if I reboot, login with GNOME's login screen, and select Blackbox as the window manager, I don't have internet. The routing table is empty and I can't get an IPv4 address with DHCP.

I can then log out ( from the session with Blackbox ), select GNOME, log in, and my internet is all set up. Everything works.

I can then log out of the GNOME session, select Blackbox, log in, and my internet works.

So... I have to log in with GNOME just to get internet for some reason, but I don't know where to look. How could I get internet with Blackbox without logging with GNOME first?

  • Do you really mean "can't get an IP address", or do you actually mean "won't get an IP address"? In other words, are you manually starting a DHCP client from Blackbox, or are you expecting that to happen all by itself?

  • Well, I tried to get an IP address with dhclient( ie. manually ), but there's no offers. So, I was wondering how GNOME did it automatically, so I can put something together that runs when I start with Blackbox.

  • Are you talking about WiFi or Ethernet here?

  • Ethernet, dhclient eth0, when run with Blackbox, doesn't get offers.... That doesn't mean to imply Blackbox is stopping it, but somehow, GNOME can get internet, but Blackbox can't.

  • What do you use for the network in GNOME, then? NetworkManager?

Make sure NetworkManager.service is active/running. My guess is that it's not "enabled" for automatic startup, but GNOME still launches it via DBus (but Blackbox of course doesn't).

nm-applet is optional, but still recommended, since it handles interactive prompts (e.g. Wi-Fi password prompts).

  • It seems, with Blackbox and my computer, service network-manager start results in [ ok ] Starting network connection manager: NetworkManager already started. but still no internet :( might work for someone else though :D
