clipboard not working when connecting via rdesktop to xrdp-sesman

I have a Debian machine with xrdp-sesman setup following way Xvnc 127.0.0.1:5910 xrdp-sesman 127.0.0.1:3350 xrdp 0.0.0.0:3389 I am connecting to this machine with rdesktop from another Debian machine. Everything works great, except clipboard (i.e. using Ctrl+c Ctrl+v to copy and paste). When I connect from my Debian machine to a windows machine using the same rdesktop client, the clipboard works OK. I suspect that the reason why clipboard does not work when connecting to sesman is that it is using rdp over vnc (or something like that). I don't understand how sesman works, I have just reused config I have found somewhere. This is my /etc/xrdp/xrdp.ini: [globals] bitmap_cache=yes bitmap_compression=yes port=3389 crypt_level=low channel_code=1 [xrdp1] name=sesman-Xvnc lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=-1 **How can I make clipboard work when connecting to xrdp-sesman with rdesktop client?**
