Subject: Re: Bug#291100: xscreensaver won't start with XDMCP setup

I suspect this is a bug in the xrandr extension.

I can work around it by trapping errors around that call if this is, in
fact, a common bug (as opposed to something specific to your setup, or
your version of the server.)  But I'd like to hear what the X folks have
to say about it first, though.  Is it valid for 

  XRRSelectInput (dpy, root, RRScreenChangeNotifyMask);

to return BadValue if the server has already claimed to support the
RANDR extension?  That doesn't sound reasonable to me, but that seems to
be what's happening.

Just to make sure this is what's going on, please grab the xscreensaver
source and do this:

    ./configure
    cd driver
    make test-randr
    ./test-randr

and see if you get the same error.  You should see something like:

    test-randr: 19:12:34: XRRQueryExtension(dpy, ...) ==> 117, 0
    test-randr: 19:12:34: XRRQueryVersion(dpy, ...) ==> 1, 1

[Message part 1 (text/plain, inline)]

Based on the previous mail to this bug, including a patch to the
*server-side* implementation of xrandr, this bug should be reassigned to
the X server, package xserver-xfree86.
