dga does't work correctly

[Pawel K]

I have successfully enabled XAA/EXA with composite but unfortunately it did not speed up my xmame.

I have
Intel Graphics Media Accelerator (GMA) 3100 (onboard, integrated)

and I use i810 (chipset Q35) driver for it.

Help me PLEASE to enable DGA on it.

Great thanks for any help to all of YOU.

Which video driver are you using?
You could try to switch to XAA, if you're using an open-source driver.
