ATI R600/700 3D Support In Fedora 12
Phoronix: ATI R600/700 3D Support In Fedora 12
Fedora 12 provides "out of the box" support for kernel mode-setting with ATI R600/700 series graphics hardware, but it does not provide 3D acceleration by default. However, Red Hat's X developers have made it very easy to enable this 3D support for the ATI Radeon HD 2000, 3000, and 4000 series hardware by just installing a special Mesa package from yum. In this article we are taking a quick look at where the R600/700 3D support is at in Fedora 12.
Excellent. Also, Catalyst 9.10 finally works on Fedora 11.
Doesnt work well for me .
Made a fresh install of the 64bit beta updated it and installed the experimental package for my 2900pro.
Now it mostly hard locked in gdm or sometimes gives me about 10min before X frezes
The open source radeon driver does not correctly display on Mitsubishi's new line of DLPs. It is horribly overscanned. The TV allows "1080p reduce" but then it's horribly underscanned. On Windows or with the proprietary drivers the image is slightly underscanned (without the 1080p reduce). The Catalyst Control Center then allows correcting for underscan. I have not been able to find any overscan/underscan correction for radeonhd.
Typical with DLP's. Might be time to upgrade to LCD.

I've seen a lot of newer TVs which display computer outputs perfectly, both LCD and LED TVs. I'm just waiting until they're low enough in price and big enough then I'll upgrade, but yes it is stupid that these DLP TVs don't display computer output correctly and can function as a big monitor. We usually leave it overscanning unless there's a real reason to see the boarders, and then change it to reduced mode.

There appears to be more than one bug manifesting as the system hanging shortly after login. If pcie_aspm=off as a kernel parameter works around the problem for you, that is indeed:
if that parameter doesn't seem to have any effect, take a look at:
those are the ones I'm currently tracking. 'nomodeset' may suffice as a workaround, try that.
I'd like to know whether my Power Mac G5's Radeon x800 will be working under Fedora 12? It wasn't with 11.
Right... x800 should have been working since F...9?

Could also be something to do with the KMS stuff that was really in a "not sure if its coming or going" state in F11, might want to try to just force-disable KMS. I think the kernel parameter is "nomodeset" (or something like that).
Might also help if you describe what it does (or does not) do in more details... "not working" doesn't give anybody much to go on.
