I wasn't using the closed source drivers.
In fact, I have not found any for my board ATI Radeon 7500.
So I'm using whatever xorg is giving me.
ATi's driver is supposed to support most of their cards for x86 platform, from 7000 and up.
Keep in mind that a badly installed driver may not use the right opengl libs, but MESA which is really slow as every 3D calculation is done in CPU instead of GPU.
Did you mean VESA? Although Slack comes with a nice VESA driver, I
opted to run xorgconfig and specify my hardware.
No, I ment MESA, it's the software opengl library that is used when no hardware using driver is found.
You will have to check the kernel settings, as that where most of the radeon magic is located.
You need to have "Support for frame buffer devices" enabled, and "ATI Radeon display support". There is today an older driver, you can try to compile it and use it instead of the new one (it's too included in the kernel), could be that one works better for your graphics card.
