Compiling free edition 4.1.3 on SUSE 10.1/11.1

I am attempting to compile VNC on SuSE 10.1 using gcc 4.1.2.  I am compiling
because I want GLX and input extension.

My uname -a is:
Linux mymach 2.6.16.54-0.2.5-smp #1 SMP Mon Jan 21 13:29:51 UTC 2008 x86_64 x86_64 x86_64 GNU/Linux

I used X11R6.9.0-src.tar.gz and vnc-4_1_3-unixsrc.tar.gz, unpacked them and
get all the way to:

vncExtInit.cc: In function 'int ProcVncExtGetQueryConnect(_Client*)':
vncExtInit.cc:754: error: cast from 'void*' to 'CARD32' loses precision

I've searched the KB and googled for the error (and found it) but there isn't a
clear answer on what to do.  I am not a C programmer.  

Would someone have a step-by-step fix for this?

thanks for any help!

tom

Unfortunately, I was mistaken about that fix.  I think the problem has 
something to do with full-screen mode.  If I am not in full screen mode, 
my ctrl keys don't work -- not for keystrokes and not for mouse clicks -- 
but they do work in full-screen mode.  When I am connecting to localhost, 
it seems that after some time my control keys will stop working correctly, 
losing their persistence, but when I leave full-screen mode and return to 
it, they will work correctly again.  Leaving full-screen mode to change 
Gnome settings provided a temporary fix, but not because I had changed the 
settings.  So this issue remains "NOT SOLVED."  ;-(

That's interesting.  I'll have to see if I have it set to "normal" on my 
office machine (where I have the problem that I don't see at home), but it 
is set to "none" on my home machine (and I think it is "none" in the 
office, too).

I recently noticed that my control keys seem to be totally nonfunctional 
when I am not in full-screen mode.  This is true with both the RealVNC 
Free viewer and the Enterprise Edition viewer.  The Enterprise version is 
the same in home and office, but it fails only in the office (where it is 
connecting to localhost), from home it is via ssh tunnel, then localhost. 
See details below.

I'm using Xvnc Free Edition 4.1.1

disable toolbar in Enterprise viewer?

When I fire up the viewer in the Linux version of the Enterprise viewer, 
the first thing I always do is disable the toolbar so that I don't get 
that little box on top of the screen.

Is there a command-line argument that I could use to prevent the toolbar 
from appearing?

Have to move browser windows to refresh inside them

Hi
Hopefully someone can assist me.  In the earlier version of RealVNC (paid 3 licence) everything worked AOK.

But now (not sure since which update)  - if I do something that causes an update on a page, eg a browser
changes pages etc, then the inside of the remote window doesn't refresh.  If I grab that remote windows
title bar and drag the window a little way (ie move the window), then the inside of it updates.

All systems are running XP or XP64.

Thanks in advance for any help,

Regards,
Dave

Why does VNC 3.3.7 on Solaris do one thing and 4.1.3 on Linux not do that?

Hello!
I have here two systems. One is a Solaris 10 from March 2005
installation on an UltraSPARC 5(10) system, and the other is a
Slackware-12.1.0 system on Intel.

The Solaris one is running 3.3.7 that was packaged by themselves (Sun)
and can present me with both an xterm screen and an rxvt terminal
screen. The Slackware-12.1 system is running 4.1.3 that was collected
from the RealVNC site sometime ago, and was translated from the
delivered rpm file.

Both present me with the default twm screen manager and an xterm upon
launching the viewer. This viewer always works no matter if its
running on Windows Seven or Linux or Solaris.

However I only get the necessary rxvt terminal on Solaris and 3.3.7.
It causes VNC to complain regarding colors that it does not know about
certain colors and causes a failed error code of -5 on 4.1.3 on
Slackware-12.1. Incidentally this Linux system is wearing the XORG
release common to Slackware from that time period. I believe it was
6.5.

However running 4.1.3 of VNC on a Slackware-11.0 system causes
everything to work properly. It has been suggested that the problem
might be inherent to X instead of VNC but I am open to suggestions
from the community.

As far as I know the above setup, the vnc-server is a script that starts 
the binary `Xvnc`. This is a genuine X-11 server, that can be configured

You payed for support, get it!

Once you got it, be nice to answer here with the found solution... (or 
the message that support sucks ;-)

With the remote system being msWindows, do have a look at the server 
settings. (right mouse button on the icon next to the clock). There find 
the polling settings and twiggle with them: msWindows based vnc-server 
most times use a polling mechanism and only send updates as they are found.

Maybe the viewer has also some update/refresh options, see the vncviewer 
menu (right mouse button on the title bar) for details.

VNC viewer does not show the top panel

Hi,

I used to use Putty and VNCviewer on my Laptop with Windows7 to connect to a
linux machine in our university and everything was fine until I tried to
connect to this machine using another computer with Ubuntu and xvnc4viewer.
The top panel which shows time, date, applications and other menus is now
missing. Also the bottom task bar is missing. Everything esle is fine. I
have my icons (Computer, Home, Trash) on the desktop. I can get a terminal
by right-clicking on the screen.

After this, I have the same problem everywhere even with Putty on Windows7.

Can anybody helpme please?

Regards
medimont
