[ALTSP] Проблемы с ldm и курсором

Добрый день!

1. Я поправил утилитку ltsp-update-sshkeys (что бы она работала в альте) 
- кому и куда мне выслать исправленную версию?

2. Задача была такая - поднять терминальный сервер с компрессией 
траффика. Соответственно, для этого я использовал пакет ldm из 
стабильной ветки, lts.conf следующего вида:
[default]
    NETWORK_COMPRESSION=Y
    SSH_SESSION=Y
    SERVER=192.168.1.154
    USE_XFS=Y
    XFS_SERVER=192.168.1.154
    XKBLAYOUT="us,ru"
    XKBVARIANT=",winkeys"
    XKBOPTIONS="grp:ctrl_shift_toggle"
    X_COLOR_DEPTH=16
    NBD_SWAP=Y
    SOUND=N
    SOUND_DAEMON=pulseaudio
    SOUND_VOL=80
    LOCALDEV=Y
    INFO=Y
    POWER_BUTTON=Y

После старта ldm курсор имеет вид тёмного, мигающего при перемещении 
(движение мышью) небольшого квадратика. Такой же курсор наблюдался при 
использовании стандартной XDMCP сессии с менеджером дисплеев gdm 
(присоединялись к терминальному серверу на SLES). При присоединении к 
тому же серверу из Thinstation - всё отлично. Т.е. косяк где до внутри 
(A)LTSP. Никто не сталкивался?

При вводе логина и пароля в ldm - выдаётся чёрный экран и снова окно ldm 
после некоторого ожидания.

В /var/log/ldm.log пишется следующее:

Что делать? Куда копать, что читать?
