Bug#692579: Workaround: fix xauth in Xsession

[paul.szabo at sydney.edu.au]

My workaround is to fix xauth settings in /etc/gdm3/Xsession by adding
the lines

# PSz 31 Jan 2014  Fix up weird xauth setting that upsets "ssh -X".
xauth list 2>/dev/null | perl -ne '
  ($h,$s,$m,$c)=m/^#ffff#((?:3\d|2e)*)#:(\S+)\s+(MIT\S+)\s+([0-9a-f]{32})$/ and
    $h=~s/2e/./g and $h=~s/3(\d)/$1/g and
    system "xauth add $h:$s $m $c";
    exit'

to that script, somewhere before the
SESSIONFILES=$(run_parts $SYSSESSIONDIR)
block.

Cheers, Paul
