Question ATI Radeon/onboard graphics Direct rendering problems

Hi People,

I have a problem getting my ATI Radeon 7000 graphics card working with my motherboard.
The motherboard is a ASRock p414gv with an intergrated Intel 82845G/GL/GE graphics card.

When I disable the onboard graphics by selecting AGP in the BIOS the linux kernel 2.6.17
crashes when it loads the module INTEL_AGP

If I compile a kernel that does not include INTEL_AGP the machine boots and I can get the
Radeon ATI 7000 card to work BUT direct rendering does not work.

From Xorg.0.log:
(WW) RADEON(0): [agp] AGP not avaliable.
(EE) RADEON(0): [agp] AGP failed to initialize. Disabling the DRI.
(II) RADEON(0): [agp] You may want to make sure the agpgart kernel module is loaded before the radeon kernel module.

The AGPGART module is first on the list in my /etc/modules file.

I assume that AGPGART requires INTEL_AGP to work, but it crashes on my system.
Is there a way to load the INTEL_AGP module without it trying to initialize the
onboard graphics (which is disabled) and crashing?

I have tried loading the ATI_AGP module with no luck.

I thank you for your time.

PS: I am planning to use a ATI 9600 on this machine, but if the 7000 does not
DRI then I dont think that the 9600 will.

Just to make sure try removing your radeon module and agpgart and reinserting to make absolutely sure they are loaded in the right order.

Hi Azriel,

Thank you for the reply, I have tried doing that to no avail. Even the Ubuntu live CD crashes on this machine unless the onboard graphics is enabled.

Thank you for the responce.

PS: I am thinking of binnig this motherboard

Is your kernel getting into a module loading race? Mine failed continually until I entered via-agp into /etc/modules so that it would load first.

Mine looks like this:

# /etc/modules: kernel modules to load at boot time.
# This file should contain the names of kernel modules that are
# to be loaded at boot time, one per line. Comments begin with
# a "#", and everything on the line after them are ignored.

via-agp #added to start agpgart first



If you are using Intel, you probably need a different module, but you get the idea.
