Cubietruck Armbian Bionic xrdp remote desktop doesnt work

October 26, 20187 yr

Hello. I've installed the newest Armbian Bionic Ubuntu with the Desktop on my Cubietruck. In the past i had Debian Wheezy running on it with working remote desktop connection over Windows 10 (sesman-xvnc).

Now with the new Ubuntu i cant connect anymore to my Cubietruck. If i open the Remote Desktop Tool on Windows 10 i get a connection to my Cubietruck and i can see the login Screen. But there is no more an option (sesman-xvnc). I can only see (xvnc). If i connect through this option i can login to my cubietruck. If login is successful i see only an empty desktop without elements and without a background-image.

How can i solve this issue? I have installed "tightvncserver" and "xrdp" used this tutorial: http://www.microdev.it/wp/en/2016/08/11/remote-desktop-setup-for-armbian-on-orange-pi-pc/

You can connect with root user while it doesn't work as a normal one.

Fixing 3rd party user applications bugs is not a part of support and since unrelated to Cubietruck - moving to Peer to peer section.

I logged in as root user. But desktop is empty. No taskbar, nothing.

I just happen to install Debian Stretch on Cubietruck http://ix.io/1q4l and I can login as a root, while user login gives this in the logs:

I experience the same problem in x86 Ubuntu and already wasted time on this ... and since it's impossible to fix all upstream problems, I won't proceed. Try VNC server or look deeper into the problem ...

But don't have any experiences. I use CLI most of the time.

Hi,

I’ve found a fix for xrdp. The permissions required fixing!

For a non-root user, Xorg is not starting because it is not able to write the Xorg.10.log file to the location /home/{user}/.local/share/xorg

This xorg directory needs to be created with user ownership not root!

i.e.

sudo mkdir /home/user/.local/share/xorg
sudo chown user:user /home/user/.local/share/xorg

FWIW, I found out this by connecting to the xrdp and sesman services, having them running in the foreground to see the diagnostic output.

window 1.

    sudo systemctl stop xrdp.service
    sudo mkdir -p /var/run/xrdp/sockdir
    sudo xrdp -ns

window 2.

    sudo /usr/sbin/xrdp-sesman -ns

When connecting from the client (in my case xfreerdp) window 2 showed

-[20190224-19:06:54] [INFO ] Xorg :10 -auth .Xauthority -config xrdp/xorg.conf -noreset -nolisten tcp  
(EE)
Fatal server error:
(EE) Cannot open log file "/home/adrian/.local/share/xorg/Xorg.10.log"
(EE)
(EE)
Please consult the The X.Org Foundation support
    at http://wiki.x.org
for help.
(EE)

BTW, on my desktop build I’ve installed xorgxrdp and done “dpkg-reconfigure xserver-xorg-legacy” to configure xorg access for anybody rather than console.

You shouldn’t need to install VNC services (tightvncserver etc…) for your xrdp experience!

Hope this helps.
