I've got a strange issue here that I came across, I was looking in the ATI Control Center and noticed my AGP was running at 0x (pci mode), so I went to investigate and looked in my /var/log/Xorg.0.log and noticed this:
Its detecting my card as a pci express card? Thats not right, my card is AGP, now that explains why i'm running at 0x (pci mode), but I haven't figured out how to fix this. I'm guessing it might be a problem with the drivers concerning the pcie-agp bridge on the card itself, since thats how ATI/AMD has done their AGP cards since X1k.
(II) Module fglrxdrm: vendor="FireGL - ATI Technologies Inc."
compiled for 7.1.0, module version = 8.39.4
ABI class: X.Org Server Extension, version 0.3
(--) fglrx(0): VideoRAM: 262144 kByte, Type: DDR3
(II) fglrx(0): PCIE card detected
(WW) fglrx(0): board is an unknown third party board, chipset is supported
Oh by the way, opengl/hardware acceleration does work.
I don't think its a problem concerning my xorg.conf as i've switched settings around and played with the useinternalagpgart setting with no luck. I'm guessing i've had this problem since day 1, just haven't noticed it until now, now i'm curious.
