copying to the X clipboard causes disconnect from tightvnc

[jlapeyre]

Calling XStoreBuffer() causes a disconnect when using tightvnc. This happens
on at least two linux architectures and with several clients.
This bug was reported on debian bts in 2010. I also see the same bug.
I use a workaround that adds a single line to vnc.c ignoring a particular error.
This stops the disconnect, but does not fix the bug.

I'm seeing this as well with XRDP, using Windows Remote Desktop to connect. Any action that would copy to the clipboard results in a disconnect.

I do exact the same steps of installing xrdp and tigervnc under CentOS 6.7, see Install XRDP Remote Desktop to CentOS 6.5 » Ramblings of an IT Guy.. Basically, it is xrdp 0.6.1 official release.

I also see a quite similar bug, it looks like vncconfig is not running, so basically the clipboard is not supported as stated by the vncconfig document. I can manually run vncconfig, but after that if I copy anything, the session get disconnected. I see other people also state this bug in the wepage here: Remote Desktops with VNC and RDP | SysteMajik Consulting

Were you able get clipboard sharing to work with xrdp? I read somewhere that you need to run “vncconfig -nowin” for this and confirmed from the man page that it should work, but the first time I ran it, the session got disconnected. I was able to connect back, but whenever I try to copy something, the session gets disconnected, so I ended up killing vncconfig.

Any one know how to solve this issue? Do I need to use a git version of xrdp? Thanks.

EDIT: when using the VNC viewer with tigerVNC, clipboard works fine.

From a comment in #162, see on 24 Feb 2015, some guy suggest using x11rdp instead of xvnc, so my question is that dose xrdp not support clipboard if xvnc backend is used?

I find another similar bug report in xrdp's developer maillist, but without any response, see here: xrdp-0.6.1: Clipboard doesn't work without vncconfig, with it disconnects (and also doesn't work)

I had similar problems a couple months back with xrdp and/or X2Go in combination with tightvnc, if I remember right. Part of the problem is that tightvnc is basically abandoned now with no recent releases/maintenance. It's not a good choice.

Try using TigerVNC. It seems to be currently-maintained and it fixed some of the weird X server problems I was having, including this one. For some reason it's not in the Ubuntu package repositories but TigerVNC has .deb files you can download.

Hi, JohnstonJ, when using the latest TigerVNC(the preview binary 1.70), this issue still exists.
