Hi there,

well, i'm new here - so please be nice to me

i've got a t41p (what a great machine!)
i'm currently installing gentoo linux on it... arrived at the xfree installation, i found out being unable to get the 3d-acceleration (i.e. dri) working...

has anybody a 3d-accelerated machine under (preferably) gentoo linux?
i'd need some "support"

thank you.

cheers, raist.

You need to be a bit more specific here, Raistlin. How far did you get into it? You emerged xfree and then what? Did you try configuring it? If your machine has an ATi card, did you try getting 'ati-drivers'? If you did, those come with a config utility of their own.

oh, sorry
well, i emerged xfree: no problems, i.e. xserver starts correctly, and twm gets up and running.
then i first tried "emerge ati-drivers".
this resulted in a error of the drm tool module: fglrx.ko produces a kernel oops, so it gets unloaded. (the same is with the manually downloaded binaries from ati - they are actually the same)
configuring xfree with fglrxconfig works well - the xserver gets up. i just don't have any 3d-acceleration. it could "not load dri" is the message from fglrx(0) out of the logfile.

i compiled my kernel (vanilla 2.6.6, for a mm3-patched 2.6.6 results in _real_ compiling errors "structure does not have a member 'count' " (agpgart_be.c, line 1405)...) once with agpgart as a module and once into the kernel... i activated "drm".

so, currently i'm a bit depressed.

i would really appreciate having the knowledge of a 3d-accelerated t41p under linux (the distribution is secondary, for i think i could "get inspired")

thank you for all replies.

cheers, rolf.

No need to be depressed; I've been there before. Basically, your only problem is obviously the kernel not liking the module. I think what I have always done is enabled agpgart for the Radeon but DISABLE DRM in the kernel. The ATi drivers actually serve that purpose in this case. Give that a try.

Also, just make sure that the kernel module actually gets compiled against the kernel source (aha! you sure you have your /usr/src/linux symlink set up properly?). You actually have to do this every time you upgrade your kernel (not recompile but upgrade - change the source).

Let me know how it goes.

[solved]

I got it
i almoust got desperate, because everything i did was exactly as i've read it in several how-tos... my kernel-config matched in the specific parts the needs... so i absolutely had no idea why i got a kernel-oops when i tried to load the fglrx-module (and therefore i had no dri...)

i found out - after nearly 2.5 days trying around, reinstalling, recompiling... that the kernel-configuration-option "mregparm=3" is _incompatible_ with the fglrx-module (i enabled it due to an advice of a friend of mine - well, he has an nvidia-adapter *g*)

anyways, now i have 3d-acceleration:

HTML Code:
#glxgears
10592 frames in 5.0 seconds = 2118.400 FPS
10594 frames in 5.0 seconds = 2118.800 FPS
thank you for your support

cheers, raistlin
