    Hi.

    Regarding my X-windows configuration problem, I was told

    > This information is readily available on the web:
    >
    > http://support.ap.dell.com/docs/monitors/p793/En/specs.htm
    >
    > Resolution

    > Vertical scan range 50 Hz to 160 Hz (automatic)
    > Optimal preset resolution 1024 x 768 at 85 Hz
    > Highest preset resolution 1600 x 1200 at 75 Hz

    AFAICT, all this information is currently present in the xorg.conf
    file, except for the 85Hz. Currently, the xorg.conf file has

    Section "Monitor"
            Identifier "Monitor0"
            VendorName "DEL"
            ModelName "DELL P793"
            HorizSync 30.0 - 96.0
            VertRefresh 50 - 160
            Option "DPMS"
    EndSection

    Following the instructions in the xorg.conf manpage (as I understand
    them), I changed this to read

    Section "Monitor"
            Identifier "Monitor0"
            VendorName "DEL"
            ModelName "DELL P793"
            HorizSync 30.0 - 96.0
            VertRefresh 50 - 160
            Mode "1024x768"
               DotClock 85Hz
            EndMode
            Option "DPMS"
    EndSection

    When I ran Xorg, I got an error msg telling me that there was a parse
    error ("Unexpected token in verbose Mode entry) in this section.

    Just for fun, I tried changing the line to
               DotClock 85
    (figuring that perhaps the "Hz" was the unexpected token). I got a
    different error msg, saying that the horizontal timings are missing.

    Obviously, I'm misinterpreting the manpage's instructions. Exactly
    how should I be specifying the 85Hz clock speed?

    HOWEVER ... I'm wondering if this is a red herring. After all, we're
    able to launch X windows successfully. The problem only happens when
    terminating an X windows session, in which case we're getting the
    abberant behavior:

    (1) The screen shows a floating box with a complaint.
    (2) When the X server shuts down, it wedges, and can only be restored
        by switiching runlevels (init 3; init 5).
