    Default Newbie Monitor Issue

    RedHat 9, ATI Radeon 7000 PCI, Shamrock 19" VESA monitor.
    Installation went very smooth.
    However, monitor goes black when loading firstboot.

    In Win2K, this monitor works at the following settings:

    1024x768 48.5khz x 60hz
    1024x768 56.6khz x 70hz
    1024x768 60.1khz x 75hz
    1024x768 60.7khz x 85hz

    1280x1024 64.1khz x 60hz

    The first time I ran setup, I selected 1280x1024 60hz. Black screen on
    firstboot; The second time, I left it on the default Unknown Monitor
    settings, still black screen on firstboot.

    Suggestions? (Is it the Radeon?)

    Thanks, I'll try this, but unfortunately I suspect it is not the
    solution. I did some additional research on this issue this morning and
    apparantly there are lots of users having loss of monitor signal issues
    when trying to set up RedHat 9.

    It *could* have been that I was failing to select the right horizontal
    and vertical frequencies. It could also be that setup was failing to
    save my selected settings before rebooting.

    What's puzzling to me is that I can run the install in graphic mode.
    It's only after I finish install and reboot that the monitor loses
    signal just at the point where it is about to start firstboot.

    I'll try your suggestion; that would be really cool if it were that
    simple. But if it doesn't work, I'll try running install again and
    making sure that I select the exactly correct horizontal and vertical
    frequencies. If that doesn't work I'll try installing in text mode and
    see what it does.

    I'll report back on my progress.

    'Xf86config' utility is called 'XFree86' in RH9, try 'XFree86 -help' in
    the command line or you can try the GUI tool, 'redhat-config-xfree86'.

    Consult your monitor manual.
