Notes for building xrdpdev_drv.so and libxorgxrdp.so
------------------------------------------------------
Notes for building xrdpdev_drv.so and libxorgxrdp.so
------------------------------------------------------
Pre-requisites:
o sudo apt-get install xserver-xorg-dev
quick and easy way to build and run the driver
o cd xorg/server
o ./test-in-home.sh
o see /etc/X11/xrdp/xorg.conf to see how things are configured
to run it
create /etc/X11/xrdp
