Hello,
I am having problems getting freenx running in CentOS 4.5 i386_64. I
know this is not a new problem, however, I havn't
found a solution in all the postings I found on the web.
I did exactly what is supposed to work and described in detail at
http://wiki.centos.org/HowTos/FreeNX
After doing that I can connect to the server with nxcleint without
problem but I get only a black screen. In the files
.nx/S.../session and errors
I see the warning
Warning: Unrecognized session type 'unix-gnome'. Assuming agent session.
The same happens with KDE.
With the command
nxloadconfig --check
I get the output
Warning: Could not find nxdesktop in /usr/bin. RDP sessions won't work.
Warning: Could not find nxviewer in /usr/bin. VNC sessions won't work.
Warning: Invalid value "APPLICATION_LIBRARY_PRELOAD=/usr/lib/

libXcompext.so:/usr/lib/libXrender.so.1.2". /usr/lib/libX11.so.6.2
could not be found. Users will not be able to run a single
application in non-rootless mode.

Warning: "/usr/lib/cups/backend/smb" is not executable.
Users will not be able to enable printing.
Warning: Invalid value "COMMAND_START_CDE=cdwm"
Users will not be able to request a CDE session.
Warning: Invalid cupsd version of "/usr/sbin/cupsd". Need version 1.2.
Users will not be able to enable printing.
Error: Could not find 1.5.0 or 2.[01].0 or 3.0.0 version string in
nxagent. NX 1.5.0 or 2.[01].0 or 3.0.0 backend is needed for this
version of FreeNX.
Errors occured during config check.
Please correct the configuration file.
The libraries are definitely not where nx looks for them - they are
located at /usr/lib64/NX/lib (and symlinks under (usr/lib/NX/lib).
What is going wrong here? I also tried to use nxconfig with --setup-
nomachine-key with the same results, except that
I did not need to import the key in the nxclient anymore.
Does anyone has an idea to solve the problem?
Many thanks for help
Michael

Indeed, its a x86_64 cluster (more precisely 4 (master) + 16 (nodes) processor AMD Opteron machine with freenx only running on the master). The installed versions are nx-3.0.0-4.el4.centos.x86_64 freenx-0.7.1.svn416-2.el4.centos.x86_64. CentOS-4 has been install from scratch Best regards Michael Am 13.11.2007 um 22:57 schrieb Fabian Arrotin:> On Tue, 2007-11-13 at 22:14 +0100, Michael Oevermann wrote: >> Hello, >> >> I am having problems getting freenx running in CentOS 4.5 i386_64.
