Copy-Paste issues

[codegeek182]

Hi,

I suspect there's a bug in x11vnc in transferring data when pasting text to a session.
My knowledge in x11vnc is not deep enough so if you can please help me in this issue it will be really helpful.
I'm using x11vnc in order to view a rdp session with xfreerdp.
For some unknown reason I can't paste text from the host machine into the session.
When I try to simply copy and paste text from the machine into it self, it works well. I used python 2 on Ubuntu 18.04, ran gtk.wait_for_targets() and pasted inside the machine I received the wanted result - all the possible types (such as text/plain, STRING, TEXT, UTF8_STRING…):
Import gtk
a = gtk.clipboard_get()
a.wait_for_targets()

But when I connect to the machine with x11vnc, and then I try to paste text from the host machine, nothing is pasted, and when I run gtk.wait_for_targets() I get None as a result.
Do you have an idea what can cause it?

Thanks,
Tomer

I'm having trouble understanding the basic setup :-) It's you -> vnc viewer -> x11vnc ?? xfreerdp?

[codegeek182]

I'm using JavaScript library NoVNC as a viewer, x11vnc which acts as a vnc server against Xvfb display which runs in the background, and xfreerdp which is running in the xvfb and acting as a client to a remote machine (it is basically a web-RDP gateway)

I am having the same issue. I can copy from server to client but I can not copy from client to the x11vnc server.

should be fixed by #255

@elirag Thanks for the PR. I tried the patch, but for me I still can't copy from client to server (the other way works). I'm using xtigervncviewer tunneled through ssh in -listen mode, both systems run Xfce under Debian Bookworm:

xtigervncviewer -listen $vnc_port &
sleep 1
# -noxdamage s. https://github.com/LibVNC/x11vnc/issues/154
# -auth guess
ssh -T -o ConnectTimeout=12 -R $vnc_port:localhost:$vnc_port \
      "DISPLAY=:0 x11vnc -q -clear_keys -noxdamage -repeat -nopw -connect_or_exit localhost:$vnc_port"
