#8 problem with double quote
I am using Xvnc only.
The problem refers to the double quote character, which
is the shifted 2 on a UK keyboard; the @ sign, which is
shifted apostrophe on UK keyboard, has the same problem
too.
If I type fast, I often get "2 instead of just plain "
(this is not a quoted phrase, the quotes are literally
characters). At first I thought it was just my bad
typing, then I thought it was the keyboard, then I
thought it was vnc in general but, after extensive
research and comparisons, I am pretty sure that it only
happens with Xvnc from the xf4vnc version.
That is to say, I think it _doesn't_ happen with the
Xvnc from TightVNC but it does with both the released
and beta versions of Xvnc from xf4vnc.

I doubt this is xf4vnc specific.
What OS are you using as the viewer ?
What kernel are you using on the Xvnc server ?
Is it in an xterm, emacs something else ?
more details of the enviroment would be good.

My reason for thinking it is to do with xf4vnc is that if I
switch back and forth between the Tightvnc and xf4vnc
versions of Xvnc I can consistently reproduce the problem
with the xf4vnc version but don't get the problem with Tightvnc.
I get the problem with the vncviewer on both WinXP and Linux.
I get the problem on two machines running Xvnc server,
kernels are:
Linux G2 2.4.19-gentoo-r9 #3 Tue Nov 19 18:38:29 GMT 2002
i686 AMD Athlon(tm) Processor AuthenticAMD
and
Linux mail 2.4.20 #2 Thu Dec 5 23:20:42 UTC 2002 i586
AMD-K6(tm) 3D processor AuthenticAMD GNU/Linux
It happens with xterm, gnome-terminal, openoffice.org, mozilla.
It looks like a key bounce problem but only happens on a
couple of keys, notably the double quote. I have tried
altering the keyboard repeat rate with xset, but I suspect
that vnc does not pay any attention to this.

I'll try and take a look this week, but I don't know if I'll be able
to replicate it.
Can you try starting Xvnc without the XKB extension by using
the -kb flag to Xvnc.
Logged In: YES

Just had chance to try this now, and I can't replicate this at
all.
Unfortunately I won't be able to fix it until I can actually see
the problem.

I have started Xvnc with -kb option and this seems to have
cured the double quote problem; I am not clear what the
implications of this might be, I have tried reading some of
the documentation but it's over my head.

it's disabling the XKeyboard Extension. tightVNC doesn't have
this extension at all.
When I release xf4vnc 4.3.0 at the end of Feb, can you try
this again.

I get a similar problem.
When I type quickly, some of the characters I type are
entered twice.
e.g. If I type "dir" quickly, sometimes I get "ddir" at my
prompt. This is with XTerm and ATerm. The above also
occur when I type in other applications, such as Mozilla.
I am running the viewer on WinXP (TightVNC viewer), whereas
the Linux machine is running Mandrake 9.1 RC1 (default
kernel 2.4.21-pre4-6), and KDE 3.1 as my window manager.
I am running xf4vnc 4.2.0.1 with the r128 4.2.0 driver.
xf4vnc is great otherwise!! Extremely fast, and exactly what I
wanted. The reason why I didn't use the KDE 3.1 desktop
sharing feature was that it wasn't available for non-root users
as an uninvited connection. i.e. someone at the terminal had
to generate an invitation each time. I just wanted to remote
control my desktop from another machine at all times.
Please let me know if I can help you track this bug down -- I
don't like typing slow! :-)

I just tried this with a FreeBSD VNC viewer (no tight
extensions). It worked fine.
I then tried it with the original Windows VNC viewer. The
same problem occurred. If I turn all the settings off (basically
use RAW encoding, and nothing else), it still occurs.

As mentioned furthur down in this open report....
If you start X with the -kb option, then this works.

It works! Thanks! :-)

Problem still exists with xf4vnc 4.3.0. This may be because
of the error that shows up in the log file when the -kb
option is not set, as follows:

You'll need the new xkbcomp files from XFree86 4.3.0 try

I have upgraded my Xfree86 to 4.3.0 so taht I now have the
xkbcomp files.
Following your instructions, I am now launching Xvnc without
-kb. I get the following in my .vnc/host:4.log:-

> Error: Can't find file "unknown" for geometry

I have also run "setxkbmap -rules xfree86 -layout us" from
within a terminal in client session, which gives me:-

Couldn't interpret _XKB_RULES_NAMES property

the above command completes without comment in a real X session.
I have read the man for xkbcomp and setxkbmap but have to
admit to not understanding what I am looking at.

Tony, from this you need to add the flag -noreset to your
Xserver to stop
this double output.
And can you let me know whether it's still happening.
Logged In: YES
user_id=2372
Can you try 4.3.0.2 and let me know
Logged In: YES
user_id=337107
I can see no difference on this issue with version 4.3.0.2.
That is to say that I get the "2 feature unless I use the
-kb option.
However, the double output has gone away even without the
-noreset flag.
The error message:
The XKEYBOARD keymap compiler (xkbcomp) reports:
> Error: Can't find file "unknown" for
geometry
include
> Exiting
> Abandoning geometry file
"default"
Errors from xkbcomp are not fatal to the X server
still appears in the Xvnc log.
And I still get the segmentation fault when trying to run:
#setxkbmap -rules xfree86 -layout us
Please let me know if I can give you any further info.

I've convinced myself that these two bugs you reported are
problems with xkb. I'll try to find them, but don't hold your
breath. It may get fixed in XFree86, in which case I'll import
the fix if it does.
