Because freenx-knx at kde.org sent mail to me today on digest of its news.
So, I teach genetics for 30 years every semister by now.
So, it was time I have to digest my experiance in to a paper submit to
genetic proceeding today.
This is the 1st draft I just write it in half an hour.
I expect to finish it in this week and submit pass the dead line Jan 16,
2009 as original request.
I welcome any idea of discussion.

Yes, it is enabled, and the mouse works. I realised, however, that my
original description is not entirely correct. The keyboard does work--it
is just mapped completely wrong. Most keys have no mapping at all, but a
few keys do work. For instance, like I said, caps lock works. And I also
noticed that backspace works as the enter key!

Here is a collection of all the patches I am running on freenx just in
case anyone else might find them useful. Some of them, with some tidying
up, could be incorporated into freenx mainline if there is any interest.
authorization.patch
Authorisation patch. On my system, at least, nxnode fails to set up the
~/.Xauthority file correctly, because by the time it runs the xauth
command, the XAUTHORITY environment variable has already been set to
~/.nx/C-*/authority. Change the first xauth command to explicitly work
on ~/.Xauthority. Ignore the nxhost* lines or replace with your own
hostname(s) if you want to authorize connections from other than localhost.

auth_timeout.patch
If the directory server is extremely highly loaded (unusual)
authentication can take too long. Increase the timeout so that nxserver
does not give up.

If you are having problems with openoffice.org or vmware, or maybe other
applications, drastically slowing down or hanging the X server, problems
with it hanging when the X server dies, or a crash in
ValidateOnePicture() (can happen when running firefox on some web
sites), then try the following patches. I have tested them for the past
2 weeks and the issues which I mentioned previously on this list are
definitely fixed. Or upgrade to the latest nx-x11 and nxagent components
from nomachine, which include these fixes.

Don't know which system needs this patch.

The timeout should be made configurable at node.conf

xdialog is ugly and most of people prefer nxclient dialog.
Maybe it can be made configurable at node.conf

Nice. I will include it on ubuntu package.

This patch is in the svn.

Nice. I will include it on ubuntu package.

I really don't like the idea of shadowing a suspended session.
But probably should be made configurable at node.conf.

This should be moved into nxacl. That is the fine grained permissions file.

Don't think much people will actually use it.
