Hi,
I am having issues connecting to RHEL 6 system using Xorg module.
I can get to the login screen but after logging in, I get a blank screen.
I am using xrdp ver 0.9.3 with xorgxrdp ver 0.2.0.
log files and the error message are attached.

That is not a log. xrdp.log and xrdp-sesman.log will give us more helpful information.
modifying startwm,sh resolved the issue.
Can you please tell, what exectly you modify in startwm.sh?
Type that modifying help, but didn't wrote what you change...So helpless
