3.3.5: Solaris7&8, cut/paste buffers not working
Tue Dec 10 23:14:00 2002
many thanks for looking into this. Here is where I am currently at ..
using 3.3.5 server on my Unix box (Solaris8, CDE)
Running autocutsel version 06
Cut/paste between PC-Unix-PC works perfectly from PC to Unix, but is very intermittent going the other way (Unix -> PC). However I can get around this by cut and pasting something from PC to Unix, then cut/paste from Unix works again. Very, very tedious but better than having no cut/paste functionality at all.
at a convenient point I want to shut down my 3.3.5 server and install 3.3.6. Also I want to switch to using a xstartup configuration I got from a recent email posted by Charles Hines to this mailing list.
A quick test the other day on another Solaris8 machine suggests this xstartup, with autocutsel may work.
Here is the xstartup I am planning to use ..
xsetroot -solid grey
#xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
I will let you know how I get on. Please don't spend any time modifying a version of 'x2vnc' for me, although it is very kind of you to offer.
I must say that as great as VNC is, I have been surprised by lack of proper cut/paste support, or at least with my Solaris8/CDE setup. This can't be an uncommon setup for people to use these days can it? I suppose this is why Michael Witrant created autocutsel, unfortunately when I had to migrate from Solaris 2.5 to 2.8 autocustsel stopped working reliably.

I finally got around to looking into this. While I am not running CDE, I did
use one of the CDE apps (dtpad) to investigate this.
To understand what is going on, you need to know that X (including the Xvnc)
has two copy and paste mechanisms: the cut buffer, and the selection
mechanism. In addition, the selection mechanism can support multiple copy and
Most modern applications, including CDE and KDE, use only the selection
With VNC, there are two problems:
1) The VNC Server (Xvnc) cannot set the 'selection' mechanism used by CDE
(and others) for the copy and paste buffer; it can only set the cut buffer.
2) CDE uses the selection name of 'CLIPBOARD'; the VNC viewer uses the name
'PRIMARY'. CDE does not use the cut buffer at all.
What this means is that for your configuration (where you are viewing a VNC
server), at least, there currently is no solution outside of 'autocutsel'. It
may be possible to have some sort of VNC-specific helper app, but regardless
one will need to run a helper app of some sort. This helper application could
be a pure X application (like 'autocutsel') or a VNC client (based on x2vnc,
For the viewer, by the way, one could modify the source to use the 'CLIPBOARD'
selection instead of (or as well as) the 'PRIMARY' selection.
If you want a modified version of 'x2vnc' that just transfers the copy and
paste buffer, I can do that for you.
