I've just gotten an iMac (one of the old multi-colored ones) set up with Gentoo 1.4, including xfree-4.3.0-r3. It's using a Rage128 AGP graphics card. When I installed xfree-drm everything seemed to work, but I wasn't getting hardware acceleration as recognized by the glxinfo command. Also, I had a mysterious error message:

(EE) R128(0): FBIOPAN_DISPLAY: Invalid argument

Other than that, X worked fine at 1024x768.

Thinking that maybe the problem was that I was using it through the framebuffer, I commented out the 'Option "UseFBDev"' line in /etc/X11/XF86Config-4. Now I get this message:

(EE) R128(0): Cannot read V_BIOS (5)


Has anybody had any success with DRM on the original iMac? Thanks in advance. :)

EDIT: Oops, maybe this should go in "Linux PPC"... :o
