Hi everyone!
i think i got a little bit farther by disabling channels in the xrdp.ini
file.
but now starting the X11rdp session occasionaly times out. im having a hard
time investigating here because i can not reproduce the issue and after
some time it starts working again. so now i found something that might be
an indicator why the X11rdp session times out.
so first, connecting to sesman, channels are disabled:

i then looked into the process list and didn't see any X11rdp process so i
tried to start one by hand. it didn't start with the following errors.
after some time the command worked, the X11rdp session started. I stopped
it on the command line and tried via win7 rdp client and it worked again.
