Good catch.

It is also mentioned here: https://github.com/neutrinolabs/xrdp/blob/cc7d5ef921938ff4a04e6efe5d0228712abaf471/sesman/sesman.ini.in#L138

I wrote a loop to guess the xorg path

@jat001 - very sorry. The positional parameters are used for XORG_ARGS later in the file. I didn't check carefully enough.

I can give you a couple of options:-

1. Move the new code below the line XORG_ARGS="$@"
2. Try this patch which solves the problem a different way:-

Use whatever work best for you.

@matt335672 that's why I don't like posix sh LOL

[matt335672]

Thanks @jat001. I really shouldn't propose changes without testing them.

sh is a bit of a pig to get right, but it's always there. It's made easier with tools like shellcheck (which we haven't used for this script). Only having one array available, and no associative arrays does make it only suitable for very simple tasks though.
