Comment 8 for bug 1019314

Updated the workaround: added lightdm check, so this script does not mess with any other DM.

/etc/X11/Xsession.d/39-lightdm-dmrc-fix:
--------------
#!/bin/bash

# workaround for session language selection in lightdm greeter
# use .dmrc or accountsservice data (if accounts-daemon is running)

# we need this only if lightdm is being used
if pidof lightdm
then
 # if accountsservice is used, get info from there.
 if pidof accounts-daemon
 then
  LANGFILE="/var/lib/AccountsService/users/$USER"
 # if not, use .dmrc
 else
  LANGFILE="$HOME/.dmrc"
 fi

 # extract, fix and export $LANG
 TEMPLANG=$(cat "$LANGFILE" | grep ^Language= | cut -d '=' -f 2 | sed 's/utf8/UTF8/')
 [ ! -z "$TEMPLANG" ] && export LANG=$TEMPLANG
 # convert $LANG to $LANGUAGE and export
 TEMPLANGUAGE="$(echo $LANG | cut -d '@' -f 1 | cut -d '.' -f 1):$(echo $LANG | cut -d '@' -f 1 | cut -d '.' -f 1 | cut -d '_' -f 1)"
 [ ! -z "$TEMPLANGUAGE" ] && export LANGUAGE=$TEMPLANGUAGE
