[FreeNX-kNX] CentOS6 FreeNX never starts session

[Ryan Cooley]

I've run freenx successfully before, but on RHEL5 32-bit (x86).  Now I've just installed freenx on TWO different CentOS6.x 64-bit (x64) servers, but neither is working.

In both cases, I can login, and get an empty, black X11 window.  I know it's working that far, because I can connect to the server, set my DISPLAY to :100x and run /etc/X11/xinit/Xsession to start my window manager properly and use my NX session.  Obviously, that's not good enough, and I need to get NX launching the session on login like it should, but nothing in the logs (~/.nx/ and /var/log/nx/) indicates any problem.  --check is pretty worthless, as it always complains.

I wrote a tiny shell script that, when run, just creates a file in /tmp, filled with the date and a few user variables.  If I tell the nxclient to run that command as my shell, it is NEVER executed, as I've never seen a file show up, after dozens of attempts.  I have SELINUX disabled, and nothing is notably pathological about my installations...  One of the two is pretty plain vanilla CentOS6.x.  Now I'm trying with OpenNX, but no change.

I'd appreciate any help tracking down where this process is hanging-up.  I'm amazed there aren't more reports of problems like this, because I'm seeing a 100% failure rate on CentOS6.
