           Summary: add query for LIBXCB_ALLOW_SLOPPY_LOCK (or alternative
                    fix)
           Product: Codex
           Version: test grimoire
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: xorg-modular
        AssignedTo: sm-grimoire-bugs at lists.ibiblio.org
        ReportedBy: jblosser-smgl at firinn.org


[Marking enhancement against test since this is asking a base grimoire package
to make a concession for a z-package (Sun java), but given the use of java this
is pretty fundamental.]


I'm logging this second hand so I may get some details wrong but the gist is
this:

- Sun java has some bad multihead/xinerama linking that breaks it under current
X, specifically with a lock file argument with libxcb.

- libxcb has an environment variable that can be set to make java happy, but
reportedly this slows things down.

- Some also report patching one of the binary java libraries makes things work
via brute force.

- Sun needs to actually fix the problem.


More details are here: http://bugs.archlinux.org/task/8521
Sun's version of the bug is here:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6532373


I would suggest we add a query to the libxcb spell asking if they want
LIBXCB_ALLOW_SLOPPY_LOCK set, since this appears to be what upstream xorg has
decided to do about it for now.
