slight confusion with agpgart and DRI

xushi · 02-03-2005, 11:03 AM

Hi,

I just want to clear something out..

If i am to use ATI's graphics drivers for my machine, it would be recommended to use "external AGP" instead of the internal one? Right? It would also mean that i will not be using the DRI drivers that came with the kernel, Right?

If so, do i still have to enable the following in 2.6.10, or is it safe to remove them.

Code:

Character devices
      /dev/agpgart
      Direct Rendering Manager

Is there anything else in the kernel i'm missing?

Thanks alot.

well...the external agpgart is the one from your kernel, so thats the one you're using.
keep it.
also dri is not needed

but.....if you have prob's with X, look in the log ( /var/log/Xorg.0.log ) for errors.

It is better to compile agpgart as module, and that gives you the option of not loading it if you don't
want it

So should i use the External AGP or the Internal one?

And what about

Code:

Graphic Support
    ATI Radeon Display Support (M)

...that's oke, just don't load that module....

and for agpgart, it is advized to use the external,
but i myself have never been able to get fglrx running ok.
( the record is about 5 min.'s )

but dri does a good job for me .

With the external agpgart, i've been running fglrx with dri stable for over a week now. Occasionally every few days, i get a really strange crash, but im not sure if its related.

However, none of my games run properly. Diablo 2 runs at something like 2fps, with colors and grids missing. The problem is i dont know if its a driver issue, or some configuration i've missed.

If you want, i can show you my xorg.conf if it would help you in any way.

Is it normal to see
FATAL: module apm not found
FATAL: module agpgart not found

during bootup?!

egag · 02-03-2005, 04:20 PM

no

apm=powermanagement
agpgart=graph. interface support.

you'll need agpgart for 3d rendering. ( have you build that as a module or compiled in?)
and to see if acceleration works, type " $glxinfo "

xushi,

You mentioned if it's a problem getting FATAL agpgart and drm during boot... Strangly, when I boot with 2.6.10, I see those two lines flying by during boot up BUT the message/dmesg/Xorg.0.... Neither of them show any FATAL error being reported and xorg and 3D accel work better than ever with my card. So I don't know.

Thanks,

Yes, i have agpgart built in the kernel as well as the Intel I8xx and E7x05 chipset support (built in)

As for APM, its not (ACPI is however).

I get the same weird issue as oxblood, where these problems appear in dmesg, but not in the Xorg log, and glxinfo, glxgears, fgl_glxgears all work and display DRI, although the games fail terrebly.. I wonder if this is the reason..

Also, APM apparently works although its not compiled in the kernel (Maby its the ACPI which is doing the trick)
