Problems under Linux

Hi,
My app (http://sourceforge.net/projects/motopain)
is now using LWJGL, I just ported it from Java2d, or actually implemented lwjgl too so one can choose. Anyway, it runs OK under windows, tried on several XP machine with different hardware. Today I tried it at home under Linux on my
Laptop with AMD Turion 64 and a ATI MobilityRadeon X700 (128 MB) and it sucked. The refresh rate was so slow it was totally unplayable.
So I would be glad for any advice what might be causing this, since it runs OK under Windows.
Anyone else had the same problem?

Regards,
Anders

drivers…

Linux and ATI dont like to mix…but there are drivers for it. Im not sure how to do it as I dont have an ATI card, but for Nvidia its relatively painless…
