Subject: Re: Trying to figure out OPEN CL working

Dear all,

i'd like to add, that i succesfully used opencl to attack Office2010 about 2 
weeks ago (even if i had no guess in the time).
I run ubuntu 12.04, while it worked. Then i upgraded to 12.10 and installed 
the most recent driver.
But my GPU was not recognized any more.
i tried catalyst 12.4, 12.6, 12.8, 12.9beta (that worked before), 12.10 and 
12.11(beta).
12.11 was the only one, that recognized my GPU. But it did not work on office 
anymore.

I also run an Asus Eee PC 1201N with an ION chipset. OS Is sabayon. It works 
flawlessly there (also i only get 120c/s ).

Now i switched to Sabayon on my Notebook was well, upgraded everything and 
tried Office once again.

I can use OpenCL on wpapsk or MSCash2, but not on Office.

I guess a "better" fglrx s needed, but i wanted to add this.

GPU = AMD Mobility 6800Series, which is (according to Wikipedia) certified for 
OpenCL
