ATI is a crap. If you want to make serious 3d/video stuff in GEM on Linux or you change video card, or you go back 8.04. Meanwhile you may want to check this tips for a decent configuration of ATI cards:

Thanks for the thinkwiki.org link, I've not seen that one. I'm tempted to revert to Hardy 8.04 but have read it's also possible to just downgrade xorg. Might give this a try first. So can someone confirm it's definitely the driver and nothing to do with gem? Just want to make sure before I completely hack up my OS! Is there any other test I could do?
Jack - thanks for the gemhead tip - I had tried numbering them from 1 but it was the same result.
