Вокруг этого всего есть какая-то магия непонятная. Слишком много питона :)

Имеем сервер на p9 и клиент на Сизифе

На сервере запущена сессия

$ xpra list
/usr/bin/Xorg is suid and not readable, Xdummy support unavailable
Found the following xpra sessions:

При попытке соединиться

$ xpra attach ssh://server:2022/111

То есть нифига не работает. Однако! Если запустить xpra_launcher, то он 
вполне успешно устанавлиает соединение и все работает весьма достойно 
(за одно из лончера можно сохранить настроенное соединение в *.xpra 
файл, и запускать его как обычную иконку программы).


На сервере в /etc/xpra корфиг иксов "по умолчанию" для p9, там что-то 
про XDummy, и оно вроде бы работает как раз через него.
