I'm setting up some new VNC servers. I already have this setup working with CentOS 6.3, although I'm not certain that this difference is the real problem.
One of the window managers I'm making available is fluxbox, but when I start it, I always get the following: Error: Couldn't connect to XServer. Here's my setup:
fluxbox: fluxbox-1.1.1-5.el6.x86_64
vnc : tigervnc-server-1.1.0-5.el6_4.1.x86_64
OS : CentOS 6.4
Note that I can start other window managers: Gnome, KDE, openbox, xfce4, etc.
I gutted my ~/.vnc/xstartup script so it only loads an xterm. Then, I tried running startfluxbox &, but still got the error. Obviously, VNC is working, since my xterm opened up OK. I can start firefox, another xterm or other app requiring X, and even fluxbox comes up, but it is worthless in its current state, since it is not connected to the X session.
What is fluxbox looking for? Are there some log files I can look at to give me some clues?
Thanks,
David
