xrdp - OpenSuse 13.2

Mám instalované OpenSuse 13.2 ve virtuálu (qemu, libvirt). K němu přistupuji na nějaké lokální IP adrese routované strojem, na kterém virtuál běží atd... potud ok.

K virtuálu se připojím SSH, X (mám povolené naslouchání ... takže funguje X :1 -query 192.168.10.101), VNC skrz xinetd, nejenom tím VNC, co poskytuje virtualizér.

Rád bych se připojoval RDP protokolem, protože XRDP pro každé připojení vytvoří samostatnou persistentní session.

Jednou - při prvním pokusu - se mi to povedlo, pak jsem OpenSuse aktualizoval (normální update Yastem), párkrát rebootoval a od té doby to nefunguje. Vrtám se v tom už tak dlouho, že není šance poznat, jaký byl stav v okamžiku funkčnosti.

Firewall je aktuálně zcela vypnutý, nic není blokováno, vše je schované v lokální síti.

Verze balíčků

xrdp 0.9.0git.1420692256
xorg-x11-Xvnc 1.4.1
x11vnc 0.9.13

Dost mne u toho irituje journalctl ... ale nějak jsem se prokousal k tomu, že xrdp s vnc alespoň něco posílají do logu, takže to aktuálně při pokusu o přihlášení (které skončí hláškou viz screenshot) hlásí toto (pomocí journalctl -f):

Certifikát tam je, hláška je zřejmě jen varování, že cesta k němu není uvedená explicitně v xrdp.ini, což není (a ani při prvním funkčním pokusu nebyla).

Domnívám se, že skutečná chyba nastává před "VNC Error after security negotiation", ale problém je, že se mi k tomu nedaří najít vůbec nic. Resp. různými pokusy najdu desítku diskuzí, znichž část je trochu o něčem jiném a zbylé nekončí řešením, příp. řešení není použitelné, některé spoustu let staré.

Zajímavé taky je, že po nepovedeném pokusu o přihlášení skončí vnc jako zombie, dokud neprovedu restart xrdp.

Otázka je, co s tím?

Dá se nějak vnc přinutit, aby bylo ukecanější? Dá se nějak zjistit, proč vlastně vnc selhalo? Vlastní log nemá, v systémovém logu nic nevidím. Přehlíd jsem něco?
