I have successfully installed the EMGD 1.18 driver under Ubuntu Linux, and 2D and 3D acceleration is working. I do notice a lot of tearing when moving graphics horizontally in both 2D and 3D. Is there any option I can configure that would eliminate the tearing? I couldn't find anything related to vsync in the xorg.conf file.
I've already added "Option "ALL/1/General/tearfb" "1" to xorg.conf but it didn't seem to make any difference. Thanks for any help.

Hi,
Unfortunately I don't have access to any of those operating systems so I can't test on them. I take it tearing hasn't been an issue on these OS's before?

Hello trs79,
Thanks for your reply.
We suggest you these Operating Systems because they are mentioned as the supported to this platform, so we want to confirm if the problem persists using them. They are listed on page 2 of the attached Intel(R) Atom(TM) Processor Z5xx Series and Intel(R) System Controller Hub US15W Product Brief.
It is important to let you know that any condition out of the stated at the documentation should be tested and validated on your own.
Please let us know if this information is useful to you.
Best Regards,
Carlos_A.
