    Ctrl+Alt+F1 = Problems Ubuntu 12.04 LTS

    Hey all! I've been using Ubuntu 12.04 LTS for almost a month now and I love it! I wanted to start playing some old Steam games on it, but I have out of date drivers, so I get an error message at Steam's launch. I am using a GeForce 6200. To update my drivers, I went to the nVidia website and got the latest drivers for my system. The only way I could get them was as a .run file. I executed them in terminal as described on the Ubuntu website and got error messages about the X environment and such. I learned that I had to use Ctrl + Alt + F1 to go to a command line and exit the GUI. When I pressed those keys, the screen flickered and had lines all over it. I couldn't do anything except Ctrl + Alt + F7. That took me back to the desktop GUI, but the background had the same lines from the "command line" screen. It stayed like that until I did a reboot. I tried updating everything, no help. I had no programs running. I also tried the terminal command "sudo service lightdm stop" didn't help, same lines on the screen.

    So, any ides on how to fix it? Thanks!

    Hi Purple Narwhal. Welcome to the forums

    I'd recommend uninstalling that driver, and following these instructions to install the proper Nvidia driver (310-experimental).

    Regards.

    Thanks for replying. Unfortunately, my system says it it not using any proprietary drivers when I go to additional drivers.

    What can I do to fix this? Thanks!

    Let's do it manually then.

    Make sure you removed the one you installed from the site:
    Code:
    sudo NVIDIA-Linux-xxx-xxx.xx.run --uninstall
    Replace "NVIDIA-Linux-xxx-xxx.xx.run" with the actual name of the script you downloaded.

    Clean the house:
    Code:
    sudo apt-get purge nvidia-*
    
    sudo rm -rf /etc/X11/xorg.conf
    Then restart your machine.

    Once you get into the desktop again, install the Steam driver:
    Code:
    sudo apt-get install nvidia-experimental-310
    Create the X config file:
    Code:
    sudo nvidia-xconfig
    Restart. Now you should be using the proper Nvidia driver for Steam.

    Let us know how it goes.
    Regards.

    When I did exactly what you said and rebooted after installing the experimental drivers, Ubuntu couldn't startup. I get a black screen. I can go into the recovery console by holding shift if there is a way to fix this problem.

    Thanks!

    Sorry to hear that.

    Let's try the current stable version then:

    Boot until you get the black screen, wait a minute or so, and go to text-mode console by pressing Ctrl+Alt+F1

    Login and uninstall the previous driver:
    Code:
    sudo apt-get purge nvidia-*
    
    sudo rm -rf /etc/X11/xorg.conf
    Then restart your machine.

    Once you get into the desktop again, install the normal driver:
    Code:
    sudo apt-get install nvidia-current
    Create the X config file:
    Code:
    sudo nvidia-xconfig
    Restart:
    Code:
    sudo reboot
    Let us know how it goes.
    Regards.

    Thanks for helping, but I cannot get to the command line using Ctrl + Alt + F1. It has no response on the black screen. What should I try now?

    Boot into recovery mode. You can't install anything, but at least you can remove packages:
    Code:
    sudo apt-get purge nvidia-*
    
    sudo rm -rf /etc/X11/xorg.conf
    
    sudo reboot
    Let us know if that helps.
    Regards.

    Well, uninstalling the old drivers in recovery mode and then re installing the current normal drivers through terminal worked! I can run steam and it shows up in additional drivers! I still can't use Ctrl Alt F1. This is what it looks like (See attachment)

    Glad you got Steam working

    At this moment, I don't know why it does not go to text mode. I can suggest trying Ctrl+Alt-F2 through Ctrl+Alt-F6.

    If that doesn't get you there, you may want to try the boot option called 'nomodeset':
    Code:
    gksudo gedit /etc/defualt/grub
    Look for a like that looks like this:
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    Add nomodeset to it so it looks like this:
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
    Save the file, and reboot.

    Let us know if that fixes the text mode problem.
    Regards.
