I'm just wondering if anyone else uses hardware that must use the open source ati / radeon driver. I have a Thinkpad T41 and I seem to be able to enable 3D desktop effects but even though I can check 'composite' (plus XRender or OpenGL), I'm not sure if everything is working or enabled. I don't see windows 'bend' or anything like that.
At least, nothing crashes, though. In Ubuntu Karmic 9.10, I have to edit xorg.conf and even then, I haven't been able to enter/find a combination of xorg settings that allows me to use desktop effects without major problems. If I use XAA acceleration, it soon crashes the entire desktop system and I need a hard restart. If I use EXA, I can have effects running but it doesn't repaint properly and constantly flickers like mad.
I have some screen 'corruption' or artifacts (not sure what to call it) with 3D effects enabled checked in Fedora 12 but at least I don't get a crash that requires a power off/on. Kudos for Fedora being the only recent distro so far that allows some sort of operation of desktop effects on my old laptop.
My main reason for this post, though, is if anyone can tell me what the status is or what the general experience is using the open source radeon driver in Fedora 12. Especially for older ATI cards like the Radeon 9000 (my card). I've noticed a lot of posts regarding newer ATI proprietary drivers (fglrx) but nothing yet regarding the open source radeon driver. Does anyone have an experience to report regarding a similar configuration to mine? Just curious.
Anyway, many thanks for any input or info which would be both interesting and potentially helpful.
