I am experiencing the same problem described here:
http://lists.apple.com/archives/X11-users/2010/Jan/msg00028.html
when I try to remotely run an application using X forwarding via SSH.
The remote side (running the application) is a Ubuntu 11.04 machine. Some applications
run without problems (glxgears for example), but some quit immediately :
freeglut (./glapp): ERROR: Internal error <FBConfig with necessary capabilities not found> in function fgOpenWindow
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 4 (X_DestroyWindow)
Resource id in failed request: 0x0
Serial number of failed request: 25
Current serial number in output stream: 28
What confuses me is where to look for the cause of this problem: is it my macbook or the remote machine?
The following is the output of glxinfo (note that direct rendering is automatically disabled):
name of display: localhost:10.0
Xlib: extension "NV-GLX" missing on display "localhost:10.0".
Xlib: extension "NV-GLX" missing on display "localhost:10.0".
display: localhost:10 screen: 0
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)
