XRDP sur Ubuntu Mate 16.04 - Erreur lors de la connexion

Installation fraîche et mise à jour de Ubuntu Mate 16.04 sur un OptiPlex 780 Dell.

Connexion d'un client Windows 10.

Installé XRDP directement après et essayé de se connecter de Windows.

Entré dans la session RDP et entré les informations d'identification. Puis...

A cette erreur.

Connecting to sesman IP 127.0.0.1 port 3350

A couru cette commande

:~$ Sudo netstat -peant | grep "127.0.0.1"

Et a eu:

tcp        0      0 127.0.0.1:3350          0.0.0.0:*              LISTEN      0          39396       8082/xrdp-sesman

Essayé la même chose avec Grepping "5910" Andit n'a rien retourné.

Essayé de supprimer XRDP, puis installez d'abord SittVncServer, créant ainsi une connexion VNC Desktop, puis installez XRDP car c'est comme ça que je l'avais configuré avant d'autres ordinateurs;

J'utilisais VNC sur d'autres ordinateurs puis découvert XRDP, puis installé XDRP, tué les ordinateurs de bureau: 1 et a pu utiliser XRDP sans le moindre attelage.

Sur ce bureau, le service XRDP était bien en cours d'exécution à la suite du résultat du chèque SystemCTL.

Essayé Connectez ensuite affiché mon/var/journal/syslog et c'était le résultat:

Obtenu des idées de ce fil,

Erreur/problème de connexion (Windows 10 RDP dans XRDP)

Qui fait référence à celui-ci ...

https://ubuntuforums.org/showthread.php?t=1314336

Mais, pas de dés.

Devrais-je faire quelque chose différemment dans le mate?

Devrais-je poster cela dans l'autre fil?

Aidez-moi, Ubuntu Mates!

METTRE À JOUR!

N'a rien changé mais redémarré. Vous avez la même erreur la première fois, mais ensuite ...

Maintenant, je peux me connecter à partir de l'invite de connexion XRDP entièrement sans les erreurs précédentes, mais obtenez cet écran pixelisé gregné.

wowowers! beaucoup plus facile que je pensais. Je viens d'utiliser cette simple directive XSTARTUP et cette utilisation de la CPU faible et une excellente connexion.

#!/bin/bash
xrdb $HOME/.Xresources
startmate &

Je pensais évidemment cela et je ne suis pas allé correctement sur la configuration.

Maintenant je sais:

  1. installer serrevnc
  2. démarrage: 1 Desktop Tuer alors pour créer le répertoire ~/.vnc et les configs
  3. assurez-vous que la directive XSTARTUP est la superbe double doublure ci-dessus et écrase si nécessaire.
  4. installer XRDP
  5. démarrez le: 1 bureau de bureau à nouveau
  6. connectez-vous à l'aide de mon client RDP préféré, Remmina!
  7. essayez de nouvelles choses, faites des erreurs, demandez-vous Guyziz à ce sujet, dépannez-vous et obtenez-vous d'une manière ou d'une autre pour en savoir plus sur votre fonctionnement!

Merci, Ubuntu Mates!
