Соединиться с Ubuntu 18.04 через RDP?

Такое чувство, что RDPing в мою машину Ubuntu зависит от погоды, звезд или луны. Иногда это работает, иногда это не делает. Я попробовал различные меры, включая которые я нашел в руководствах онлайн:

• Используя RDP от ppa:martinx/xrdp-hwe-18.04
• Выполнение эха "сессия гнома - session=ubuntu-2d"> .xsession
• Соединение с сессией X11 RDP и затем нормальной сессией RDP
• Добавление RDP группе ssl-сертификата

Я произвел чистку RDP, переустановленного, очищенного снова - без удачи.

Нет никакого реального сообщения об ошибке - просто, что что-то пошло не так, как надо, и это находится там.

Это - сообщение об ошибке, что я вхожу в клиент Windows RDP:

Вот является вывод журнала xrdp.log:
