missing extension in Xnest

After starting Xnest session to server (RedHat AS3) the extension XKEYBOARD
is missing.
So the keyboard extensions are not implemented and I have to work with the standard keybord driver (u.s.).

ubuntu client:
$ xdpyinfo | grep XKEYBOARD

RedHat server after Xnest login:
$ xdpyinfo | grep XKEYBOARD

This problem exists with ubuntu 6.10 & 7.04.

Xnest details:

Package: xnest
Maintainer: Ubuntu Core Developers <>
Architecture: i386
Source: xorg-server
Version: 2:1.2.0-3ubuntu8

This was reported to the ubuntu support forum. Any idea?

It seems everyone has this problem - apart from those who use in any case the U.S. 104 key keyboard.

It is hardwired into the source of xnest.

I am wondering how one can fool the program - such as creating a symlink to the keyboard we are using and naming it as if it were the U.S. keyboard.

I have also played around with the keyboard extensions option (-kb +kb) and it seems to ignore it.

With regard to the symlink I find it so difficult to understand how X organises and references the keyboard layouts I would be most grateful if anyone could develop this idea of providing a falsely named symlink.

That, together with the security problem - xnest has to run with the option -ac before you can use the nested server - are the only hold-ups I've met so far in using xnest.

At the moment I now run two servers: one on :0 and one on :1 - not the best solution but better than nothing.


keyboards, xnest
