    Re: Ubuntu 12.04 Fresh install problems

    OK sorry I just read your original post again and it doesn't sound like your issue is anything to do with graphics mode setting / drivers - just that you can't update or repair the desktop because of lack of network connectivity?

    Is there an option to go into safe mode with networking?

    Iampanda;
    Chipset and driver are identified and the only driver with full support is loaded.
    I agree with steeldriver, need to get ya up on the 'net and get ya updated.
    Then see bout getting the desktop back.
    This is a fresh (re)install and not updated, correct ?
    back'n up and regroup'n

    Re: Ubuntu 12.04 Fresh install problems

    Correct. However, when I try to update (sudo apt-get update) it fails to fetch the updates. It finds a bunch and says that it will need this much space, do I want to continue, I say yes and it goes through and fails to fetch them all. Could that be a network problem? It didn't have a problem connecting last time I had it installed when I updated it the first time and everything went wrong.

    Re: Ubuntu 12.04 Fresh install problems

    Well other than a network problem it could be that your selected repositories are unavailable

    Have you done basic network tests e.g.

    1. is the interface up and does it have sensible looking IPv4 parameters e.g.

    Code:
    ifconfig -a
    2. can you ping your gateway IP address?

    Code:
    ping -c4 192.168.1.1
    [adjust the 192.168.1.1 numbers based on the subnet parameters reported in (1)]

    3. can you ping an external host by IP? e.g. a google server such as

    Code:
     ping -c4 74.125.226.41
    4. can you ping an external host by name (i.e. is DNS name resolution working)?

    Code:
    ping -c4 google.com
    5. is there a sensible default route / metric?

    Code:
    ip route list

    Ok. When I plug in the internet cable now, it will pop up Wired Connection 1 Disconnected. Don't know why it's not working now.
    ifcongif -a came up with

    Re: Ubuntu 12.04 Fresh install problems

    I am not quite sure how to fix the connectivity problem now. At the login screen, it has the little network icon and when I click on it, three options are white: Wired Connection 1, disconnect, and VPN Connections. Everything else is grayed out (Wired Network, Enable Networking although it has a white check mark next to it, and Connection Information).

    Doh! I just typed out a big reply assuming you were still stuck in the recovery console

    If 'Wired connection 1' thinks it's connected, but 'ifconfig eth0' shows no valid IPv4 address, then it sounds like there is a problem with your network card / driver or possibly with your DHCP service - can you open a terminal and do

    Code:
    sudo lshw -C network
    and

    Code:
    dmesg | grep eth0
    and report back

    Re: Ubuntu 12.04 Fresh install problems

    For future use (As I'm almost positive I will need to do much more terminal codes and relay them to you), is there a shortcut to print the screen and auto-save I tot a flash drive so I can easily just attach them here? Or do you prefer to have it typed out?
