#66 srdp is not working in Fedora 26 and 28

[amwfc]

Steps to reproduce:

1. install Fedora 26 through 28
2. dnf install xrdp
3. systemctl enable xrdp
4. systemctl start xrdp
5. I also shut down firewalld and disable selinux just in case

This worked in Fedora 19 OOB and still working. In F26-F28 this does not work. In all cases when connecting from a WinXP or Win7 machine using mstsc.exe the screen opens, allows to enter credentials, then there is a black screen for a while and it closes.

Please let me know what files I should attach to enable you to troubleshoot.

On the Windows side the log window ends up saying "some problem"

On the Linux side /var/log/xrdp.log is showing this:
