Hey everyone,
I picked up a dual G5 2.5GHz Power Mac the other day. It has the AGP NVIDIA GeForce 6800 Ultra card installed. I was hoping to get the nouveau driver with 2D acceleration working with it, but I have been struggling.
I stumbled on this article here:
and recompiled a 3.16.7 kernel from the Debian sources with 4k page sizes instead of the default 64k kernel page size. I also confirmed that the system is not using MSI interrupts.
When I boot, I just get a black screen after the system tries to start lightdm, a dmesg reveals this:
[ 28.113131] [drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder is 163

and some other messages like this:
[ 138.991484] nouveau E[Xorg[837]] failed to idle channel 0xcccc0000 [Xorg[837]]
Booting with nouveau.noaccel=1 works, but the software 2D acceleration makes the system unusable. Any suggestions where to go from here? I know getting an ATI card is the easy way out, but I'd like to get this 6800 Ultra I have to work if possible. Thanks for your time!
