Is it possible to get Ubuntu 8.04 truly recognize my Radeon 4650 HD? I'd like to take advantage of the 3D hardware acceleration and the dual monitor abilities of it, but I can't get the ATI drivers working. I've tried the standard ones, the radeonhd ones, the proprietary ones from ATI. I've followed a half dozen howtos, and looked at the UbuntuLinux.org forums - on which there is a thread suggesting that the linux drivers for the newer HD cards are still buggy and non-functional.
So my question: Has anyone gotten a Radeon 4000+ HD working with Ubuntu 8.04 LTS. Where, by working I mean, full dual display, HD and 3D support? How'd you do it?
