try going to /lib/modules/fglrx/build_mod, build the module, and install/insert it manually.

Ok, so you load the modules correctly, but still no dice... glxinfo and fglrxinfo tell you. However what motherboard chipset do you have? Have you tried with Internal AGP? In the event of an Nforce chipset, do you have support for it in your kernel? Sorry if I'm asking what other may already have, but this info may be rlevant.
Deffinitely, what LavaDevil recommends you is the best idea.

/me = linux noob (although not comp noob)

gfx card = ati 7500 mobility (seems to run using the 7500 drivers)

loads the splash screen then nothing

error:
open /dev/[sound/]dsp: Device or resource busy
Xlib: extension "XiG-SUNDRY-NONSTANDARD" missing on display ":0.0".
Xlib: extension "XFree86-DRI" missing on display ":0.0".
Either GL_EXT_bgra or glDrawRangeElements not supported- bailing out.

I found how to turn on 3d accel but I can't find where to turn direct rendering on.

LavaDevil94: "try going to /lib/modules/fglrx/build_mod, build the module, and install/insert it manually."

Sorry LavaDevil94, I don't know how to do that. Although, one of my friends came up with a theory. When I installpkg the ATI tgz, the libGL.so files, the mesa files should be overwritten by ATI's libGL.so files. My guess ATI didn't install in correctly. It should have Internal AGP support right? If not, how would you go about doing that? Thanks guys, I'm glad you're still pursuing this.

Thetargos:
After I run fglrxconfig (with External AGP) and reboot my computer, the first thing I do is lsmod (not in X). I look for agpgart and fglrx and the modules are there but it says (unused) not a number like 6. Naturally, it should do that because I haven't started X yet. I look under rc.modules and there is command to initiate /sbin/modprobe agpgart. I added one for fglrx. Anyways, I was think the ATI package didn't overwrite the libGL.so files (mesa) and there may be a duplicate of those files. I'm not in linux now, but I'll give it a try and reinstall the tgz. I have an MSI motherboard nForce2 and Slack 9.1 supports it just fine. I see nForce chipset message at boot time.

Yes, the libGL.so is your problem. You have to overwrite it (MAKE a backup first!). I thought you followed the manual procedure to install the driver other than installpkg... Sorry, my bad.


Mytherall:

You are using an Rv150 based chipset if my memroy serves me right. As such, the binary ATi drivers will not work for you, however. you may still be able to run OpenGL applications with the DRI latest drivers, try installing those.

To enable DRI you have to add that section to your XF86Config file, may be helpful if you posted that.

Thetargos, Can You step by step tell me what do to overwrite the files. I use locate Mesa and I get libOSMesa.so -.a -so.4 -so.0. Do I have to worry about those files too? They are located in the /usr/X11R6/lib/ directory also along with the libGL.so files. I know I'm almost there. I can't wait. Thanks for the help. Just step by step would be fine.

Thetargos, after unpacking the files for the tgz manually and putting them in their respective folders, I never came across replacing the old libGL.so files. What do I have to overwrite? Also, I can't get the fgl_glxgears to start at command line. This is not working out.

Check here. It's the ATi Linux HowTo, there should be a section on Slack... I'm not that familiar with Slack as to guide you accurately.

installed DRI succesfully but now it wont go into kde...

and when I try to play 2k4 it errors saying

I can't seem to find the XF86Config to post it's contents

It should be located under /etc/X11/

is there any particular part of that file u wanna see as it's really long... and I don't fancy typing it all out

Both the DRI section and the device section, if nothing comes up there, maybe we'll should look others, but first those two.

Section "Device"
BoardName "Radeon 7500"
BusID "1:0:0"
Driver "radeon"
Identifier "Device[0]"
Screen 0
Option "Rotate" "off"
VenderName "ATI"
EndSection

Section "DRI"
Group "video"
Mode 0660
EndSection

Change the mode on DRI to 0666, re-start your session and see if you get DRI (direct rendring) on with glxinfo. Unless you have set it up that way, of course.

it's not letting my edit XF86Config, it asks if I want to then it doesn't let me :E
