X11 startup problems

    I frequently have to use X11. For various reasons I'd rather forget, I'm having to run a Macbook (2012) from an external clone (CCCloner) running OS X 10.6.8.

    Mainly in order to keep a few X11 things running.

    Now recently, it's started misbehaving:
    First, xterm started up without any buttons/borders: Just a plain square, upper left hand corner.
    Second, it ceased to start up at all.

    After much painful fiddling with CCCloner backups, filing disks, and whatnot, O found the following fixed things:

    cp -r '/_CCC Archives/2012-05-29 (May 29) 02-00-11/usr/X11' /usr/X11

    that is, restoring the X11 directory alone was enough.

    Today: It stops working again, for no reason I can see.
    After more fiddling, and trying "xstart", I think I found "~/.Xauthority" and "~/.Xauthority-n" were missing.

    So I replaced them from the same backup as above (or rather one three days later) with

    sudo cp "/Volumes/Citronnier/_CCC Archives/2012-06-03 (June 03) 23-14-07/Users/jpconn/.Xauthority" ~/
    sudo cp "/Volumes/Citronnier/_CCC Archives/2012-06-03 (June 03) 21-10-10/Users/jpconn/.Xauthority-n" ~/

    ... and now X11 is working again, and XFig, gnu backgammon, and NoMachine are back (NXClient and XFig the most essential things there).

    Finally, though it's working, I don't know what I'm doing.

    Can anyone help fix this broken X11 ? Or explain what's going on ?

    Cheers, James

    in case it's any help to anyone, this X11 issue was solved after some hours experimentation by:

    - Removing all trace of XQuartz which I'd had a look at:
    sudo rm -rf /opt/X11* /Library/Launch*/org.macosforge.xquartz.* /Applications/Utilities/XQuartz.app /etc/*paths.d/*XQuartz
    sudo pkgutil --forget org.macosforge.xquartz.pkg

    - Replacing /usr/X11 from a backup

    - Removing ACLs from a number of files with chmod -N or chmod -RN where appropriate:

    Starting X11 with startx fromt he terminal was revealing: error messages showed what was problematic, in particular fontconfig.

    My guess is the only essential steps are removing ACLs, but I'm sure a knowledgable geek somewhere can explain this.
