XFree86 4.4 upgrade is giving me video troubles.

Hi All,

Short story:

Upgraded from Slack-9.1 to Slack-Current using swaret, now my Radeon 8500 Direct Rendering is disabled, and sometimes X crashes.

Long(ish) story:

I've been using Slack 9.1 for a long time now, with no problems. I had ATI's fglrx driver installed, 3D support working.

Today I decided that I wanted to update my machine. The first thing I did was install XFree86 4.4. Everything appeared to work fine. X would not start however; I had to change the driver from fglrx to radeon to get it working (Also had to reboot, graphics were displaying all fuzzy). Checking ATI's webpage, I found that ATI doesn't make a XF86 4.4 driver yet. YAY. Guess I should've researched this. Oh well, XFree86 4.4 comes with a Radeon driver, that will give me some 3D support, if not the greatest.

Then, I installed swaret, and updated all of my packages from 9.1 to current. I am up to date!

So my friends, running glxinfo returns:

direct rendering: No

glxgears runs at about 125 fps.

I then checked my XFree86.0.log file and I find these helpful messages:

(WW) RADEON(0): [agp] AGP not available

and

(II) RADEON(0): Direct rendering disabled

Doing a dmesg |grep agpgart, I find:

agpgart: Maximum main memory to use for agp memory: 203M
agpgart: unsupported bridge
agpgart: no supported devices found.

So. That's where I am, and that is where my Linux troubleshooting abilities end. What am I missing? I am using kernel 2.4.. Do I need to enable the radeon DRM in the kernel? I'm thinking no, because I've installed a new version of XFree86, and that should include a newer kernel module, right?

oh, and lsmod shows:

radeon 114944

Thank you for any and all replies

XFree86 sets AGP to 1x by default, so you need to change it to get better performance.

Add the following to your XF86Config under your driver:

Driver "radeon"
Option "AGPMode" "4" <---kernel 2.4.x only supports up to 4x

It also might help if you set your AGP size:

Option "AGPSize" "64" <---example

Thanks,

Unfortunately I still get the same errors in my XFree86.0.log file after making the changes you suggested MagicMan:

(WW) RADEON(0): [agp] AGP not available
(II) RADEON(0): Direct rendering disabled

It appears as if the first is that even though I want to enable AGP, I can't because it's not there in my system. Again, when I boot up my box, I get this error:

agpgart: Maximum main memory to use for agp memory: 203M
agpgart: unsupported bridge
agpgart: no supported devices found.

Is that related?

All suggestions appreciated

Thanks
ps. running glxinfo crashes X.

Just got back from installing kernel 2.6.5.

Now when I dmesg|grep agp i get:
Linux agpgart interface v0.100 (c) Dave Jones
Linux agpgart interface v0.100 (c) Dave Jones

but in my XFree86.0.log file i still see these 2 entries:

(WW) RADEON(0): [agp] AGP not available
(II) RADEON(0): Direct rendering disabled

I noticed that agpgart module wasn't loaded, so i did a :

#modprobe agpgart

and now it is loaded, but i still don't have direct rendering

running glxinfo still crashes X.

Any thoughts appreciated

Interesting.
What chipset does your mobo use for agp?

I'm running a Radeon9000 Pro under Xorg and was previously running it under X4.4 with the radeon module, too. It works fine for me.

lsmod:

Code:

mike@gobot:~$ lsmod

snd_mixer_oss,snd_via82xx,snd_pcm,snd_timer,snd_ac97_codec,snd_mpu401_uart,snd_rawmidi,snd_seq_device

I put agpgart into the kernel along with the chipset-specific agp driver.
Here's a snippet of my kernel config

Code:

mike@gobot:~$ cat /usr/src/linux/.config|grep -i agp
CONFIG_AGP=y
# CONFIG_AGP_ALI is not set
# CONFIG_AGP_ATI is not set
# CONFIG_AGP_AMD is not set
# CONFIG_AGP_AMD64 is not set
# CONFIG_AGP_INTEL is not set
# CONFIG_AGP_INTEL_MCH is not set
# CONFIG_AGP_NVIDIA is not set
# CONFIG_AGP_SIS is not set
# CONFIG_AGP_SWORKS is not set
CONFIG_AGP_VIA=y
# CONFIG_AGP_EFFICEON is not set

Perhaps this will help.
snippets from my xorg.conf

Code:

Section "Module"

# This loads the DBE extension module.

# initialisation of the XFree86-DGA extension within that module.

    EndSubsection
    Subsection "Display"
        Depth       16
        Modes       "1024x768" "800x600" "640x480"

    EndSubsection
EndSection

Section "DRI"
    Mode 0666

And that's precisely how mine is setup.

...Perhaps it's not linked, but, did you compile your kernel with gcc 2.95.3 like it's recommended?

I have a ECS K7S5A motherboard, and according to this page http://www.ecs.com.tw/products/pd_sp...product_id=192
it would be using a SIS chipset. I don't think I set that in my kernel..

Lets see...

Code:

murray@godzillax:~$ cat /usr/src/linux/.config|grep -i agp
CONFIG_AGP=y
# CONFIG_AGP_ALI is not set
CONFIG_AGP_ATI=y
# CONFIG_AGP_AMD is not set
# CONFIG_AGP_AMD64 is not set
# CONFIG_AGP_INTEL is not set
# CONFIG_AGP_INTEL_MCH is not set
# CONFIG_AGP_NVIDIA is not set
# CONFIG_AGP_SIS is not set
# CONFIG_AGP_SWORKS is not set
# CONFIG_AGP_VIA is not set
# CONFIG_AGP_EFFICEON is not set

nope. (thanks for showing me how to use that command too!)

When I get home, I will see what happens when I compile the kernel with CONFIG_AGP_SIS set. I guess I don't need to set the CONFIG_AGP_ATI either... I take it this option refers to the chipset on your motherboard and not your video card. (Hey I learned 2 things today)

thanks for your help on this. I will let you know how it goes when I test it tonight.

not too sure actually, is there a command to find out?

murray_linux · 05-04-2004, 08:19 PM

recompiling the kernel with CONFIG_AGP_SIS set did it!

THANKS!!!
