External Email - Use Caution These errors can happen when the remote machine is running Windows or Linux, but it’s a known issue with some X servers that run on Windows. When the X windows (graphics/windowing) software trying to remotely display images (which is not freeview) to a machine over the network cannot get the resources it needs, rendering images can be incomplete and report various errors. It could be something is going wrong with trying to remotely render graphics using OpenGL. You could try setting this to see if it makes a difference, $ export LIBGL_ALWAYS_INDIRECT=0 If you have an IT department, they night be able to help troubleshoot a remote connection. It could be useful to know that freeview displays images just fine when run directly on the machine you are remotely connecting to - just as you say it does on your own Mac. - R.

This is not a problem with the recon-all function as I can see the same surface file perfectly on my Mac with the fully working mac version. It seems to be a problem with my Freeview.Some additional information that may help finding the cause:When I open Freeview from Ubuntu, I get the following errors:QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-lavells1'QXcbConnection: XCB error: 170 (Unknown), sequence: 174, resource id: 90, major code: 146 (Unknown), minor code: 20QXcbConnection: XCB error: 170 (Unknown), sequence: 174, resource id: 90, major code: 146 (Unknown), minor code: 20There are no other errors in ubuntu after I load Freeview i.e. No errors in Ubuntu when I then load the surface.I hope you can help me fix this issue as soon as possible.
