Hi,

You should create a public repository (on github, bitbucket, etc) and
upload your code. This way it will be easier to track changes, fork
your code to adapt to others PI flavors ,etc

Thanks for sharing

Best regards

> Hello,
>
> I have succeeded in getting XPRA to work on an ARM-based single-board
> computer. In the hope that this might interest someone else, I recorded the
> commands I used in the form of a shell-script that I successfully ran as
> 'root'. These commands make xpra available to all users on the system. The
> script is provided here below my signature.
>
> This note provides a snapshot of my experience, after removing the sad parts
> -- hours of trial-and-error, etc. Please set (low) expectations accordingly.
>
> The board is an Orange PI Plus 2E. The monitor is my HDTV with 720i format.
> Network connection comes through wired ethernet.
>
> My first step was to install a suitable Ubuntu-based desktop OS on the
> Orange PI. This came from https://www.armbian.com; the download was named
>   Armbian_5.30_Orangepiplus2e_Ubuntu_xenial_default_3.4.113.7z
> Getting Armbian started on the board required some tuning of the file
> system, my location, the video parameters, keyboard, etc., and rebooting.
> All the usual stuff associated with installing a new OS.
>
> I went on to create a sudo-capable user account for myself, named 'philip'.
> This shows up in the last command in the script.
>
> On a freshly-rebooted OrangePI, I said "sudo su -" to get root, then ran the
> script shown below. About 2 hours later, I had a working XPRA setup on the
> little device. (Of these 2 hours, about 80 minutes were spent doing other
> constructive tasks while ffmpeg compiled.)
>
> Please note that the script requires frequent user interaction: one has to
> consent to each of the "apt-get install" commands. This allows one to see
> what's working, assess the speed of the system, and notice if something
> breaks.
>
> I use XPRA daily, but only to forward silent X-windows. This now works for
> me, and I'm satisfied. I have not pursued the many other exciting things
> XPRA can do -- e.g., sound, video, and print-forwarding. But I can report
> that X-window forwarding works nicely as both client and server. Many thanks
> to Antoine for this nice cross-platform(!) system.

> Sincerely,
> Philip
