Dear Maintainer,

I'm using xrdp on a ChromeBook, not Windows. I use the penguin Linux container on the ChromeBook
to run xfreerdp3 and I then work within a remote XFCE4 desktop and most
of my work is very text-based. I have found that when I use xterm (or uxterm), with VT100
translations to insert-selection(CLIPBOARD) into the XTerm, I get double lines.

I'm not alone. Other people have recorded this problem. Here is such a entry

http://superuser.com/questions/1156974/double-new-line-when-copy-to-konsole-on-xrdp/1940620#1940620

I contributed to this thread as Bonaparte. (The solution that satisfied the poster "stty -icrnl" is a red-herring. He is pasting into vim which recognizes carriage return as a new-line.)

Because XRDP was written for Windows clients, it converts Unix line-endings \n to Windows \r\n.
But if you are pasting to another Unix application, via a tty, then tty converts \r to \n
and the windows \r\n and becomes \n\n - and you get the double lines.
If you use the stty -icrnl trick then you get double ^M^M (ie. \r\r) instead of \n\n.

As I mention in the post at superuser, you don't get double line spacing if you use the
X11 middle button paste method.

Here are my VT100 translations:

UXTerm*VT100.cutNewline: false
UXTerm*VT100.cutToBeginningOfLine: true

UXTerm*selectToClipboard: false

UXTerm*VT100.translations: #override \n\
 Ctrl <Key>Insert: copy-selection(CLIPBOARD) \n\
 Shift <Key>Insert: insert-selection(CLIPBOARD) \n\

So I make a listing: ls -1

And then I copy it with Ctrl-Ins and paste it in od -c

Double lines because \n was converted \r\n and tty converts those to \n\n

0000100  \n   s   u   p   e   r   .   s   h  \n

So no double lines.

If I use the stty -icrnl

That works.

I also mention in the post at super-user that other Terminal Emulators (GNOME Terminal, XFCE4 Terminal) they work because they use libvte and not tty to do their translation.

If I kill the xrdp-chansrv process on the host running XRDP which supports the xterm, then
it also works, but I can't copy or paste from the ChromeBook that is running xfreerdp3.

Unfortunately for me, I can't switch over to using the libvte terminal applications.

Would the upstream developers be able to add an extra configuration setting for sesman.ini?
  ClipBoard.LineEndings = u2d | u2u
with u2d as the default? And u2u would do nothing but leave the existing line-endings unchanged

Thanks!

Wonderful application, it's my only first choice remote session tool now.
