x0vncserver does not support clipboard

[astrand]

Currently, x0vncserver has no support for sending clipboard changes to the client, or accept clipboard updates from the client.

[Racansky]

Hi,
for x0vncserver I used to run the parameters -SendCutText -AcceptCutText - then my clipboard works in both directions

[CendioOssman]

I'm afraid that can't be our x0vncserver in that case. This is the complete current code for clipboard handling right now:

void XDesktop::clientCutText(const char* str, int len) {
}

:)

I thought I found the perfect VNC server... but now this... I seriously can't catch a break with VNC!

[Mannshoch]

Is that problem still available?

[CendioOssman]

I'm afraid no one has had a look at this yet.

[ivorob]

Hi. Is the bounty active for that issue? I want to try resolve it to start working with project.

[CendioOssman]

Yes, the bounty is still active so feel free to start hacking. :)

[ivorob]

Guys, I am close to provide code to code review. But I have a several questions. Do you have some code style standard? Where can I find it. Sorry for offtopic.

[CendioOssman]

Sorry, no. You'll have to look at existing files and try to follow the same style.

After establishing a connection to X0tigervnc, I launched x11vnc -nofb -clip 4x4+0+0 to synchronise the clipboard.
This works for me.

@mathewng can you post more details of your workaround. When I try that x11vnc listens on 5901 and I don't get any clipboard transfer in tigervncviewer. I'm thinking that maybe I need to run a second viewer to get the clipboard transfer?

@ivorob how are you doing with your code? You may be able to find something in the x11vnc source code that you can modify to add to x0vncserver. I would be willing to add to the bountysource if you could get this done soon.

Yes, you are right.

My script to launch vnc server goes roughly like this
It works though there is a noticeable delay in the clipboard syncing when copying and pasting. not copy & paste but copy, wait and paste

SSH_CLIENT=...

# For display
x0tigervncserver \
-display :0 \
-localhost yes \
-useold

echo starting clipboard sync in 20 seconds
sleep 20

# For clipboard sync
sudo /usr/bin/x11vnc \
-display :0 \
-auth "${DISPLAYMANAGER_AUTH}" \
-noipv6 \
-connect_or_exit "${SSH_CLIENT%% *}:5500" \
-users meofcourse \
-nopw \
-noremote \
-nocmds \
-xrandr resize \
-xinerama \
-nomodtweak \
-clear_mods \
-skip_lockkeys \
-once \
-noxfixes \
-cursor_drag \
-repeat \
-allinput \
-bg \
-nofb \
-clip 4x4+0+0

I connect to x0tigervncserver for display
and have vncviewer in listen mode ready for x11vnc to connect to it

+ $25

[mvalley21]

I also threw $25 into the bounty pot. This would be a useful feature for many.

BTW, my workaround for now is using this program on the client and server: https://github.com/megahertz/clipboard-share

[bitcoinmeetups]

I second this. I can't believe it's been 7 years since this post and x0vncserver still can't support copy and paste from connecting unit. Come on.

[bitcoinmeetups]

How can we even use a vnc program if clipboard is not supported? What is the purpose of the program then? To watch the Terminal from a distance without being able to interact with it normally?

[bitcoinmeetups]

I also thought I had found the final solution for all the enormous vnc hassle. And then this.

[Skgland]

Note that to my knowledge this only applies for the x0vncserver not the x11 plugin (libvnc.so) see "3 Expose the local display directly" or the standalone Xvnc server.

I am currently using the libvnc.so with working copy-paste at work.

[TTimo]

Remmina has 'Send clipboard content as keystrokes' which I use as a workaround. For larger pastes I've used cryptpad or a text file on dropbox between systems.

With the whole Linux world moving to wayland I wouldn't hold my breath on seeing this addressed.

This has now been implemented via #1831. Many thanks to @gujjwal00!
