Well ive been running Apprentice on w2k for some time without probs. But now i want to run it on Linux. I have Redhat 7.3 installed with houdini 5.5.208 ….installation seems to go fine but when i try to run I only get the first splash(the blue one telling Houdini is about to start) screen and then it goes down (and i dont know where to look for error msg). I have an Asus v3800 gfx card with riva tnt2ultra xfree86 svga driver and mesa 4.2 open gl driver and running Gnome as Window manager Duron 1200mhz 320mb ram. Ive tried it under Mandrake 9.0 and got the same prob. In windows it runs fine. So my question is what types of broblem could this be? Plzz help
