[HOW-TO] Get ATI support in X with 2.6.x kernel

w00t, I only get 2000 fps with my Pentium 4 (2 Ghz), Radeon Mobility 9000 and 512 MB Mem...

Bastard.

I followed thousands of howtos, and none worked...

Until I found out to change DefaultDepth to 16

Well, quite easy, lol.

(using 2.6.5-gentoo / radeon mobility 7500)

Maybe this is helpful to someone, cause I wish I found that out
before. (I just read it in another thread here by chance)

Its good to search the forums for answers, because as you say, its impossible to not learn a lot whilst doing it.

how i got my radeon mobility M7 (7500) working on compaq evo n800c:

Kernel:rtc, agpgart, intel_agp, radeon, drm.

mobility m7 is not supported by fglrx am i right?

from XF86Config:

I get about 7800 fps in glxgears with my radeon 9800 pro.
Downgrading the driver from version 3.7.0-r1 to 3.2.8-r1 doubled the frame rate and made UT2004 play nicely as well.
However I can't get the module to work with kernel 2.6.6 so I'll stick with 2.6.5 for now.

By the way there's no way external agp will work for me. I don't even have the agp modules. Nevertheless I get great performance in UT,ET,Q3 ...

It works with 2.6.6 Vanilla and Love1 but somehow breaks with mm

Ok, I'm stumped. I'm running 2.6.6-love1, and I have rtc compiled in, nvidia-agp, agpgart compiled as modules, and nvidia-agp, agpgart and fglrx autoloading on boot. I'm reemered ati-drivers and then run opengl-update ati, but it still doesn't work. In my XFree log I get:

I fixed my own problem. I had to symlink the include and extensions folder from /usr/lib/opengl/xfree to /usr/lib/opengl/ati and then restart XFree. It works! I'm getting about 3000 fps in glxgears.

Hello, just posting in case this assists anyone else. I've finally got my system working thanks to the first posting in this thread by Lews_Therin (you may want to check it out, somewhere in the middle of the first page of the thread).

Previously I was getting errors like:
(EE) fglrx(0): cannot init AGP
(II) fglrx(0): [drm] removed 1 reserved context for kernel
(II) fglrx(0): [drm] unmapping 8192 bytes of SAREA 0xe1ac0000 at 0x401f8000
(WW) fglrx(0): ***********************************************
(WW) fglrx(0): * DRI initialization failed! *
(WW) fglrx(0): * (maybe driver kernel module missing or bad) *
(WW) fglrx(0): * 2D acceleraton available (MMIO) *
(WW) fglrx(0): * no 3D acceleration available *
(WW) fglrx(0): ********************************************* *

The specific problem in this case was the AGP chipset support, I had compiled in the nforce/nforce2 chipset support (the A7N8X is nforce2), but it was only after compiling in every possible chipset other than for AMD64 that this error went away and everything worked. My guess is the VIA chipset is what I needed (I would be surprised if it was something else), but since I don't know for certain I'll stick with having the whole bunch loaded in (it doesn't add _that_ much kernel size). Anyway, something to think about, particularly if you have an nforce2 board... I have no idea why the nforce2 chipset support wasn't enough.

I haven't read this thread past the first page, so apologies if this is duplicate information.

hmm, I used ati-drivers and my radeon 9800 runs HELLA slow I get like 20-50 fps on cs through winex... why, do the drivers for linux just suck?

ok, i'm pretty new to gentoo, and trying to get my 9500pro working, without any joy so far.
My main problem is that although 'emerge ati-drivers' _seems_ to work, it doesn't create the fglrx module to load into the kernel.

My first post, the contents of my changlog file as I tried to get
'renderering' working for Rage 128 on a 2.6.3 kernel, kind of a
running narrative.

* Rage 128 XFREE DRM and DRI issues and the 2.6.3 kernel. The
[HOW-TO] Get ATI support in X with 2.6.x kernel is really
talking about ATI chips in the ati-drivers. The Rage 128 is not
one of those chipset. However the HOW-TO was helpful.

* kernel config:
CONFIG_MTRR=y; CONFIG_AGP=m; CONFIG_AGP_INTEL=m; CONFIG_DRM=y;
CONFIG_DRM_R128=m

* I didn't put anything into /etc/modules.autoload.d/kernel-2.6.

* After the system comes up and before starting X, lsmod shows
agpgart and intel_agp are loaded. I guess hotplug loaded
them. r128 is NOT loaded.

* /usr/X11R6 /lib/X11/doc/{README.DRI, README.r128} has some
excellant documentation.

* I wanted to VIDEO_CARD="rage128" emerge xfree-drm, but emerge
said it was a 2.6 kernel issue. Hmmm. I had emerged xfree-drm
under the 2.4 kernel. What the heck -- let's give it a try
anyway.

* I have two r128 modules/drivers. One from the kernel build in
/lib/modules/2.6.3-gentoo-r1/kernel/drivers/char/drm/r128.ko and
another one in the Xfree tree from the xfree-drm pkg in
/usr/X11R6/lib/modules/dri/r128_dri.so

* Which one gets loaded -- got me, but I wanted X to make the
decision.

* My /var/log/XFree86.0.log said (II) R128(0): Direct rendering
enabled, but when I ran glwinfo it said it wasn't. lsmod showed
some r128 module had been loaded into the kernel space.

* I checked /dev/dri, it was present and changed it to chmod 777
/dev/dri. No dice

* Then I saw a post that said do a opengl-update xfree, that
solved the problem. Before 100FPS after opengl-update 350FPS--
don't laugh. glwinfo showed rendering enabled.

* The suggested options to improve performance were ignored:
(WW) R128(0): Option "AGPFastWrite" is not used
(WW) R128(0): Option "EnableDepthMoves" is not used
(WW) R128(0): Option "EnablePageFlip" is not used
(WW) R128(0): Option "NoBackBuffer" is not used

* My Rage 128 chipset?
01:00.0 VGA compatible controller: ATI Technologies Inc Rage 128
RL/VR AGP (prog-if 00 [VGA]) Subsystem: Intel Corp.: Unknown
device 464a Flags: bus master, stepping, 66Mhz, medium devsel,
latency 64, IRQ 11 Memory at f0000000 (32-bit, prefetchable)
[size=64M] I/O ports at d800 [size=256] Memory at ff9fc000
(32-bit, non-prefetchable) [size=16K] Expansion ROM at ff9c0000
[disabled] [size=128K] Capabilities: [50] AGP version 2.0
Capabilities: [5c] Power Management version 1

* Re-compile the kernel (2.6.3) w/o selecting CONFIG_DRM_128, i.e.
CONFIG_AGP=m, CONFIG_AGP_INTEL=m, CONFIG_DRM=y. I suspect the
things won't work since the error when I tried to emerge
xfree-drm said 'use the DRM in the kernel'.

* Well, that was a waste of time. X log said it failed to load
kernel module r128. Ran opengl-update xfree and restarted
X. Same thing. Set CONFIG_DRM_128=m, re-built kernel and
rendering worked.

* Note: revisit this issue when xfree-drm can be emerged into a
2.6.mumble kernel.

Hi, I tried the how-to walkthrough on the first page. The only difference is now fglrx starts up now, which it failed to do before. My original problem was I was trying to play americas army and got this error:

Can someone enlighten me on this one that why it makes a huge fps differences that I tested the fps on three different ati desktop modes, and I get some very odd results.

tested environment: 1280x1024, 24bits

single mode: 75 fps
dual-desktop mode: 4400 fps
big desktop mode: 75 fps

why is it way off in dual-desktop mode, and I thought in single mode it should have some better frames than those other two.

As I read thru the posts, most of you have at least higher than 600 fps (600~ 5000 fps). but why I only got 75 fps in single mode and big desktop mode, as I use big desktop mode daily.

I have enabled hardware acceleration too, still got no clue why can't it be at least higher than 500 fps.

current kernel spec: gentoo-dev-source 2.6.5-r1
graphic card: ATI 9800 Pro 128MB
cpu: AMD 1.4ghz thunderbird
ram: pc2700 512 MB

You might have vertical sync enabled - check the value of the "Capabilities" option in your config file. If the 3rd digit from the right is an "8", then it means v-sync is enabled (ie your framerate will never be higher than the vertical refresh rate of your monitor). To disable it, change the "8" to a "0" and restart X. Also, I think some of the dual monitor modes disable 3D acceleration, but I only ever use single head so I don't remember exactly which ones.

Question about tv-out and movies. When i try to watch movies all i get is a blue box on the tv with the movie playing on the monitor.. i have an ati 9000 128 (saphire) using the up todate ati drivers X.org everything seems to work great execpt the movies.

either totem or gxine do not show the movie on the tv.. just a big box.

any ideas?

Ok, I'm stuck. modprobe fglrx gives:
FATAL: Error inserting fglrx (/lib/modules/2.6.7-gentoo-r1/video/fglrx.ko): No such device

I have the modules rtc, agpgart and amd64_agp loaded. Same error with via_agp and radeon loaded as well.

I have a 9550 (works like a 9600), an Asus K8V motherboard and an Athlon64 CPU. I'm running it in 32-bit mode though. AMD64+ATI 3D isn't possible yet I think.

Edit: I solved the problem. Solution here.

Well after working the problem for a while i tought other peeps would be glad to have the solution too.
