По ситуации с удаленным рабочим столом - я не вижу, работает ли у вас rdesktop, а по xfreerdp кажется неправильно собран, ему явно не хватает библиотеки внутренней.

karasev@pc-8u:~/rdesktop-1.7.1$ sudo xfreerdp --no-nla --ignore-certificate -z -f -d mfc --gdi sw --plugin rdpdr --data scard:scard -- 192.168.1.223
