No window borders/decorations (Metacity) show on client machines.

[Nelson Delgado]

All clients connect fine to the server with very good speed and display quality, but all remote windows open on the upper left side of the screen or inside the local window without the window borders/decorations. This occurs at all resolutions and color depths, with or without compiz enabled.

You failed to identify what distribution you are using and what version as well as which ppa you have used for your packages. We need the architecture as well are you using the 32bit or 64bit version? You also have not specified whether you are using Gnome, KDE or some other desktop environment. It sounds to me like your window decorations are not installed, but without further information I am just guessing. You also have not identified what works on a local login. You also have not specified whether you are even using Ubuntu.

Please submit results of:
uname -a
nxserver --help

And reply to the above questions.

Jeremy, thanks for answering. Here is your requested info (server side):

NXSERVER - Version 3.2.0-74-SVN OS (GPL, using backend: 3.3.0)

------------------------0-------------------
Using Gnome 2.28.1
Using 32 bit version
PPA repo: http://ppa.launchpad.net/freenx-team/ppa/ubuntu

Upon local login, machine works fine, all window borders and decorations are
present (Metacity). Tested with and without compiz on both server and
clients, with 3 different clients (2 running Karmic Gnome and 1 running
Jaunty Gnome) and nomachines's nxclient 3.4.0-5. Tried different
combinations of the configurations in nxclient connection dialog to no
avail.

If it's of any help, I removed-purged everything associated with freenx and
installed Nomachine's version of nxclient, nxnode and nxserver to compare
results, and get the same problem, so I can presume the fault is not
directly related to freenx. Maybe the problem resides in ssh's
x11Forwarding but I cant see anything wrong with that section of
/etc/ssh/sshd_config:

X11Forwarding yes
X11DisplayOffset 10
PrintMotd no
PrintLastLog yes
TCPKeepAlive yes

...VNC (vino+vinagre) works ok... but slow, as always. SSH console logins,
sftp and mounts with sshfs all are 100% operative. Local network is 10/100
Ethernet, wired.

Can upload screenshot upon request. I'll update the bug report in Launchpad
with this new info as soon as possible.

Thanks again... Nelson

Workaround: Chosing "disable render extension" in the settings for the screen on NX Client for Windows (using Windows XP professional) made the Metacity decorations reappear for me.
