    Hi All,

    I am facing some problems regarding the Xserver while running Cadence
    in my intelx86 machine. It has XFree86 installed for XServer. While I
    am trying to run Cadence (icfb) it is prompting the following error
    and warning message and I have no clue to solve it. Please help.
    Inspite of this error message the normal display is coming properly.
    The error msg is as follows:

    *ERROR* Failed to find either 24-bit TrueColor or 8-bit PseudoColor
    Visual.
    *WARNING* Failed to find either 24-bit TrueColor or 8-pbit PseudoColor
    Visual.

    If I have to modify any XServer configuration file please provide an
    example of the config file.
    The OS details are as follows:

    Linux debjit 2.6.9-22.EL #1 Mon Sep 19 18:20:28 EDT 2005 i686 i686
    i386 GNU/Linux

    Thanks in advance for your kind help.

    Note that I don't know your exact setup, but you have to modify the X config
    file. Also, I haven't done this with more recent versions of XFree86, so my
    information may be old, but in the versions I've used, the file was
    /etc/X11/XF86config.

    There was also a program, xf86config (in /usr/X11R6/bin) for doing that
    interactively.

    You probably only need to change the DefaultDepth in section Screen and Depth
    in subsection Display to 24.

    See http://tldp.org/HOWTO/XFree86-Video-Timings-HOWTO/obsolete.html for an
    example of a defined Screen section.

    The program xdpyinfo will tell you how your display is currently configured.

    IC 5.1.41 and earlier versions of DFII will only run with an 8-bit PseudoColor
    Visual (a display configuration that uses 8-bit pixels that index into a
    colormap to get the color) or a 24-bit TrueColor Visual (a display
    configuration that uses 24-bit pixels that directly encode the color).

    IC 6.1.X and later versions of DFII will only run with a 15-bit, 16-bit or
    24-bit TrueColor Visual (PseudoColor is no longer supported in IC 6.1.X).

    If you have an IT department, they should know how to reconfigure your Linux
    machine.

    Hi Debjit,

    Are you running through VNC ?
    if so, then please run your vncserver command with the option "-depth
    24". Just append this option at the end of your command.

    Otherwise, you might need to tell us you mode of connection, local,
    remote .. etc.

    Cheers,
    Riad.
