Armbian : 22.11.4 Jammy

Kernel : 5.15.0-rockchip64 aarch64

Connecting through LAN (No wifi)

 

Hi,

 

I followed this simple ,great guide here to get remote desktop access from Windows working.

 

 

sudo apt install xrdp xorgxrdp

sudo systemctl enable xrdp

sudo reboot

 

When I use the root account to log in to an Armbian session it works seemlessly, however if I use a normal (non su) then I get the log in password screen pop up, but the desktop doesnt appear ir blinks and crashes.

 

Tailing the live system log, with dmesg -W and I get these errors

 

root@rockpro64:~# dmesg -W
[ 1057.390095] hdmi-audio-codec hdmi-audio-codec.5.auto: Only one simultaneous stream supported!
[ 1057.390855] hdmi-audio-codec hdmi-audio-codec.5.auto: ASoC: error at snd_soc_dai_startup on i2s-hifi: -22
[ 1057.391983]  ff8a0000.i2s-i2s-hifi: soc_pcm_open() failed (-22)

 

Anyone know how I can login as non root ?

Maybe the user account needs to be added to xrdp or similar usergroup for permission?

[Prax]

Im having the same problem. I only can login with root using xrdp.

 

AlwaysGroupCheck in sesman.ini already is on false. Group shouldnt matter.

 

 

[audioz]

yes i have the same problem 

please help 

i dont want login on root 

 

[Prax]

Which GUI are you using? I deinstalled xrdp and Im using gnome remote desktop without problems now.

[GianniDPC]

I have the same problem. Does anyone have a solution? I'm using Armbian 23.02 btw. This is really annoying.. If there isn't any fix does anyone know a version where I could downgrade to were this issue wasn't present?

[unspecified]

I also have encountered this problem and have some additional information to share. I have found that I can only log in to Armbian (from Windows) using RDP from an account that has never logged in to the Armbian console before, for example, the root account. However, once I log in to such an account at the Armbian console, I am no longer able to log in to Armbian via that account using RDP. Interestingly, this limitation persists even if I delete and re-add the account without logging in via the console.   As a workaround I could create a local and a remote account and never log in to the remote account from the console.  I've added some system information from the inxi command output.

I also use it with Jammy / Gnome, image with preinstalled desktop, and it works.

tells nothing. Logs or at least telling a lot more then "i am using Armbian". Besides different HW properties that could cause troubles, there are different package releases and different DEs.

Log from armbian monitor:

I'm using this image:https://redirect.armbian.com/orangepipc/Jammy_current_xfce.

 

FYI: I have deleted the user that was created the first time just to test, and recreated that user myself. Only difference is it doesn't close my Remote Desktop application like before but instead i get a blueish screen with the message "connection problem, giving up" after some time. I tried different things to get it working but I'm at a loss here..

I solve this problem. You need to disable user autologin in ligthtDM. Configure /etc/lightdm/lightdm.conf file, or create him if they not exist. Content of lightdm.conf:

[Seat:*]

autologin-guest=false

autologin-user=

autologin-user-timeout=0

[unspecified]

I have it working now. I tested it on a fresh installation.

 

The issue was resolved by installing the 'xauth' command:

 

sudo apt-get update

sudo apt install xauth

 

After installing 'xauth', RDP connections from Windows worked as expected.

 

I'm not entirely sure why this fixed the problem, but my hypothesis is that 'xauth' is required to add the authorization information used to connect to the X server and stored in the '.Xauthority' file.

retracted workaround, added solution

[Bel101]

I had same issue. Fixed by disabling autologin in `/etc/gdm3/custom.conf`
