    Ubuntu 12.04.4 runs for a few minutes then becomes unresponsive

    I have been running Ubuntu 12.04 LTS on my Dell Optiplex 755 desktop and ACer laptop for a year or so with few issues. Both run very well now. I am installing Ubuntu 12.04.4 onto my brother's desktop, wiping out Windows XP, and reconfiguring the partitions all from a bootable USB drive. The install went well. I set up his username and password, installed Gnome shell to replace Unity. The system will boot, let me log in and then it may be (1.) unresponsive to the mouse -or- (2.) Be unresponsive to mouse clicks when I move the mouse to try to do anything (3.) After a few minutes it seems to have some type of GPU issue and reboots to the Password screen. After that it only shows the Unity Background. No task bars at top or bottom of screen. Do I have a GPU conflict with a 9400GT? The on board GPU does not work at all. Any guidance would be appreciated.

    Thanks

    South_Canadian_Denizen; Hi !

    What processor is the machine running ? How much ram is installed ?
    Now-a-days it takes some horsepower to run the flagship edition ubuntu !
    Ya might consider (if the specs are low) to install Lubuntu.

    I personally am impressed as to how well Lubuntu performs on older hardware.

    just my thought

    Thanks for your reply Bashing-om,

    I don't think the hardware itself is dated. It's a couple of years old.
    Biostar MCP6P M2+ motherboard
    AMD Athlon 64x2 Dual Core
    A bunch of RAM, don't recll how much.

    I believe I have trace the problem to a conflict with Gnome. I uninstalle Gnome and the system ran for several hours with no problems whereas Gnome would throw a System Program Problem Detected almost immediately after login.

    Since it ran so well with Ubuntu (which I understand is aka Unity) I tried re-installing Gnome. This time instead of the Gnome Shell I installed Gnome Desktop Environment. The problem manifested itself during install and subesquent re-boots.

    I just have to puzzle this out now, why Unity seems ok yet Gnome is not.

    Thanks again for your input.

    South_Canadian_Denizen; Hey,

    That hardware is well good 'nuff to run ubuntu for sure !

    unity and Gnome-shell are reported to co-exist well. Is this the command you used to install gnome-shell ?
    Code:
    sudo apt-get install gnome-shell
    to install the version from the software repository.

    We may also want to see your graphics card and info:
    Code:
    sudo lshw -C display
    lspci -nnk | grep -iA3 vga
    Maybe think about changing the graphics driver ?

    gotta be a cause
    that we can affect

    Bashing-om, Thank you

    Your suggestions fixed my problem perfectly.

    As soon I saw your suggestion of updating the drivers I did just that with;
    sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
    sudo apt-get update
    sudo apt-get install nvidia-current

    I also took your advice and downloaded Gnome from;
    sudo apt-get install gnome-shell

    instead of the Ubuntu Software Center

    I am up and running.
    Thanks for your help
