Hello

I have little problem with UBUNTU. Im totaly new in linux, but everything works ok, houdini is stable but. If I hit render buttom from selection and handle control bar, Mplay dont show. I click on render on mantra node, rendering proces dont show, something rendering but it seem freeze. If I in menu render/Mplay/open file, Mplay open correctly. Does anybody know where could be problem? Thanks a lot

P.S.: ver 10.0.595

Start houdini from the command line. It might spit out some usefull error messages.

are you by acident creating .ifd files instead of rendering the image ?
have a look at your mantra node if this option is enabled.
you could also open your render scheduler and see if mantra was started and is running.
