Hi everyone.
We require an RDP client to run in a headless environment and process the
screen's contents, but the idea was for it to rely on FreeRDP to actually
handle most of the heavy work regarding parsing the protocol and using X11
to create and maintain the framebuffer. As such, instead of basing this
work in the sample client, it was based on the X11 client in the project.
The screen itself isn't needed per-se, we just want a simple way to do some
work on the framebuffer's contents as the session goes along.
However, since the client is running on a headless environment, it's got no
$DISPLAY, and as such, the X approach won't work as simply as I thought.
I'm aware that running a virtual X server is probably the way to go, but I
wanted to put this out there just in case there's a simple known way to
avoid that.
Thanks for your help,
Well I really think you should have taken the sample client as an
example and do the framebuffer stuff yourself. Writing a RDP client
using FreeRDP libs is not that complicated, and you have plenty of
examples in the clients directory (you can also have a look at remmina).
Even if you use a virtual X environment with xfreerdp, you may hit the
bug that some virtual X don't support all the X11 extension that we require.
Best regards.
