[vtkusers] Offscreen Rendering & Linux

[endlosschleife1]

Hello,

has anybody some experience with doing offscreen rendering under Linux with
graphics acceleration support and give me some hints on how to get this to
work?

I'm using a vtkOpenGLRenderWindow and set OffScreenRendering to on. With
that it does really not render into a window, but VTK still opens an X
Window (apparently it needs its handle). So for instance when I try to start
a VTK based app remotely via SSH I get the following error message:

# An unexpected error has been detected by Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0xb2b5b4f5, pid=16472, tid=3044047776

#
# If you would like to submit a bug report, please visit:

#

Is there any way around the need for VTK to open an X window? Basically I
would like to know if that problem is even fixable or if I need to look for
other workarounds.

When I build VTK with MESA enabled it works, but the performance without
accelaration is unacceptable.

Thanks,
Mark
