Hi @mrcorp34

I've converted this to a question rather than an issue (e.i. bug), as you haven't provided the information we need to investigate this as a bug.

Can you provide the following info:

• Contents of /var/log/xrdp-sesman.log after trying to connect.
• Output of xrdp -v

That will let me identify the exact version of xrdp you are using, and what is happening when xrdp tries to start the X server.

Thanks.
