Hi Guys, i Just recently upgraded to Ubuntu version 10.10 64bit. When i go to open Houdini the splash screen comes up, once it dissappears Houdini opens for maybe 2secs then is gone. Its more like a flash. I have tried reinstalling Houdini, trying different versions, and even reinstalling my video card drivers. Here is my specs thanks in advance

Amd phenom x4 9850
ati radeon hd3870 driver version 10.9
4gig ddr2 pc1066
Ubuntu 10.10 64bit
