Description das_deniz 2006-10-30 22:42:04 EST
Description of problem:

running vncserver on linux host and vncclient on winxp has no support for
cut-and-paste between the winxp clipboard and the X selection.

Version-Release number of selected component (if applicable):

rh9, rhel4, fc6... realvnc

How reproducible:

always need xclipboard running and to play games to get an X selection into the
windows clipboard and vice versa

Steps to Reproduce:
1. start vncserver on linux
2. start vncclient on winxp - connect to host:display
3. select some text in a terminal or application and edit->copy it
4. move to the winxp client and try to paste the text into an app
Actual results:

fails to paste selected text from X and fails the other way as well

Expected results:

for copy and paste to work between vncclient and host of client program.

Additional info:

please have a look at this very short comment with references to other sources
and my current work around:


thank you very much

Really interesting. Problem is that windows vnc client synchronize vncserver's
cutbuffer, not clipboard. I can write patch which synchronizing server's
cutbuffer & clipboard buffer but this patch will be only temporary because using
cutbuffer is VERY obsolete. In future windows vnc client must be rewrited to
using standard X copy/paste scheme.

Adam, thanks for looking into this - please do take your time with this one and
 follow these links to have a look at this *well discussed* issue around X
old/new vs Windows and clipboard handling:


also note that i missed this - part of the vnc-server package:


and this is in the default created ~/.vnc/xstartup as 'vncconfig -iconic &' with

The problem persists with 'remote access' to the desktop display :0.0 (LibVNCServer)

So, i suggest some more reading and working with the vnc providers to come up
with a solution that works for most everyone....


Thank you very much for looking into this.

Could you please specify how can you copy some text from windows vnc client to
linux server? I can't find how can I reproduce this bug. (where is edit->copy in
windows vnc client?)
Comment 4 das_deniz 2006-12-05 08:56:46 EST

I only use Edit->Copy as a last resort for any application on any platform.

Selecting the text and Ctrl-C copies the selection to the clipboard in windows 
likewise Ctrl-Shift-C copies to the clipboard for gnome-terminal.

Pasting is done with Ctrl-V in windows (if i've somthing in the clipboard) 
likewise Ctrl-Shift-V pastes in gnome-terminal.

Emacs uses different selection/buffer key sequences...

I do not use application menus or the vnc 'copy local to remote' or 'copy remote
to local' selections... and the point is no one should need to.

Clipboard synchronization works when vncconfig utility is running in session. From vncconfig manual page:

"... Its main purpose when run in this mode is to support clipboard transfer to and from the VNC viewer(s). Note that without a running instance of vncconfig there will be no clipboard support ..."

If running vncconfig doesn't help please reopen this bug.
