My server has no xorg-server installed and only a ATI ES1000 graphic card and just some programs which I need for openfoam and paraview. This bug does not happen, if I connect from my client to another desktop client with full kde4 installation and Nvidia graphic card installed. My client has also kde4 and Nvidia graphic card. After two days of headache I found a workaround (from http://forum.parallels.com/showthread.php?t=18081), one has to set on the server after log in: export LIBGL_ALWAYS_INDIRECT=yes But why do I have to set the indirect GLX rendering explicit by hand? If I login into another desktop client, this is set by default. And why has it worked before the last update (my last update of this machine was approximately one year ago)?

Hi Oliver, I am not quite sure what we can do about this from a paraview point of view. It looks to me that this would affect any application that does direct rendering with your particular setup. Any suggestions? Thanks, Markus
Hello Markus, ok I understand that this problem is not a paraview specific one. It seems to be a general OpenGL problem. If I change my opengl implementation with eselect from nvidia to xorg-x11 on a remote desktop machine, where I'm logged in with X11 forwarding, then I run also into this trouble with glxinfo and glxgears. ~ $ glxgears Error: couldn't get an RGB, Double-buffered visual ~ $ glxinfo name of display: localhost:10.0 Error: couldn't find RGB GLX visual or fbconfig So it is maybe a problem with mesa rather than with paraview.

Hopefully they can give us some insight. Thanks, Markus
