  • X Server problem?

    From home" @21:1/5 to All on Tue Aug 8 10:11:30 2023
    hello,

    I have one of these rare IntelliStation 185s, GXT4500P, AIX 6.1.
    When I ssh to a Linux box and run Firefox 102.13.0esr, I get X errors:
    ...
    'BadValue (integer parameter out of range for operation)'.
    (Details: serial 138 error_code 2 request_code 129 (SHAPE) minor_code 2)
    ...

    Same on a 285, GXT6500P, AIX 7.1.
    Funnily, on an oldish 44P, GXT3000P, AIX 5.3, it works.
    Older versions of Firefox ran, just as other X clients.

    What's wrong with these "modern" X servers on AIX 6.1/7.1
    in contrast to the older ones?

    I would first try 'firefox -no-remote' on Linux.
    Maybe this could help by trying other options.

    https://wiki.mozilla.org/Firefox/CommandLineOptions#Linux

    If that fails, if possible, try compiling a newer OpenSSH
    on AIX replacing what is there. Could be the ssh on AIX
    is rather old.

    Try some other switches.

    Personally I would blame Linux and freedesktop.org
    with them "fixing X".

    Good Luck

    tried
    firefox --sync --new-instance --safe-mode
    to no avail.

    I don't think it's an ssh problem, rather an X one.

    me too, but just blaming doesn't solve the problem.
    Moreover, the same Ff works with the AIX 5.3 X server which is from 2009.
    So I'm inclined to blame IBM for having built in some showstopper in their later X servers (from 2021 on AIX 7.1).

    Makes sense. I wonder if a setting changed in sshd_config
    or ssh_config. Can you compare those against the 2009
    versions ?

    I use to have AIX access, but recentially retired so that
    access is lost. And now that I think of it, the ssh that
    came with AIX is OpenSSH (at least for us), so getting a
    newer version of ssh probably will not work as you said.

    Request code 2 is ShapeMask, which generates a Value error should the
    client produce an invalid destKind. Recent versions of Firefox exploit
    the ``input region'', which is most likely absent from the AIX X server.

    Given ``Linux desktop'' developers' penchant for neglecting backwards compatibility or interoperability concerns, I'd chalk the problem up to
    Firefox unconditionally modifying the input region without first
    verifying that the Shape extension is new enough to support it.

    Is there something extra to configure on 6.1 and 7.1?

    No idea, since I don't use AIX. One possibility is the old AIX X server neglects performing strict verification on the parameters to Shape
    requests, which the new server does. Running Firefox under a tool such
    as `xscope' should enable you to ascertain the constituent parameters of
    the request X cannot grok.
