hopefully this might help someone.

i have a Toshiba Satellite M305D-S4830, running ubuntu 9.04 64bit and H10. the grfx is an integrated radeon 3100 IGP. Catalyst 9.8 installed and worked, but the 3D viewport, the shelf and various other parts would disappear and only reappear when clicked and then they'd disappear again. Sometimes it was hard to find them. ;o)

I attempted upgrading to Catalyst 9.9 with no luck. ubuntu would not boot correctly if at all. Eventually, i went back to 9.8 and …

turned off Visual Effects ( System -> Pref -> Appearance -> Visual Effects tab ) and Houdini runs like a charm ( and glxgears shows improved perf as well ).
