[  4882.147] (EE) Unable to locate/open config file: "xrdp/xorg.conf"

Looks like xorgxrdp isn't installed.

[USeebi]

I did miss xorgxrdp but I still face the problem of root login only.

Anyhow many thanks!

[matt335672]

For the root login only, check you've got a path specified for Xorg in sesman.ini. Instructions are in the file.

Thanks for the follow up, The path to Xorg is correct and I did try to change
TerminalServerUsers=tsusers to TerminalServerUsers=orangepi but no help

There's not really enough to go on here. I suggest you raise an issue on this so we've got more information about your setup. OrangePI has had some weird edge cases in the past (e.g. #2021) so this could be another one of those.
