    No video display after installing debian


    Hi my computer boots up but just as its about to load debian I lose video output. Where do I start with troubleshooting this? Thank you.

    Also there was an option to install debain as "graphical installation" or just "installation". I chose just "installation", whats the difference? I dont know if that has anything to do with why i cant get output.

    It doesn't directly affect it; this choice only controls how the installer works. What matters after installation is:
    a) Whether you actually installed a graphical desktop such as gnome or lxde
    b) Whether you have any problems with your video card driver that are preventing X from working.

    I would start by logging in at the text terminal and typing startx. If you get "Command not found", then X is not installed and you will have to install it. Log in as root and type apt-get install gnome.

    If you see a partial attempt to get to a desktop, then it is just a matter of posting up the /var/log/Xorg.0.log file and someone can help you find out where and why X broke. Don't worry, this kind of glitch is usually easy to fix.

    What happens when you log in and type startx?

    Is there much point in installing all 5 DVDs? I did but is it just for extra apps?

    So try typing rm /tmp/.X0-lock and then startx.

    I wouldn't install the whole of Debian unless I had a very big hard drive. Everything essential is on the first disk, The others, as you have guessed, contain alternative apps.
    Debian runs a "popularity contest" for apps (for which you may register if you like) and puts them on the discs in order of popularity with users.

    Well, it looks more and more to me as if X is actually running, whether you can see it or not. A quick test is to type
    Code:
    ps ax|grep X
    . This uses the grep utility to extract the relevant line from a list of all running processes.

    If you do get a line for /usr/bin/X, then X is running. In which case, if you can't see anything on the screen, you have a video card problem.

    The next stage after that will be to post the contents of /var/log/Xorg.0.log so that people more expert on hardware than I am can see what X actually reports about your hardware. They'll probably want to see your Xorg configuration file (/etc/X11/xorg.conf) as well.
