Open up xterm.
Type lspci followed by enter.
It'll reply with your hardware information.
In the list look for AGP
This is what lspci says about my AGP.
01:00.0 VGA compatible controller: ATI Technologies Inc 3D Rage Pro AGP 1X/2X (rev 5c)

I tried that it didn't work. It give me an error "sh:Ispci: not found" it is Ispci with an "i" right? It looks that's not a command. I'm using Slitaz 3.0. The Ispci is not the same function as the tazhw detect-pci.

Yes, it's an "i"

tux@slitaz:~$ which lspci
/usr/bin/lspci

This command search's for tazpkg containing filename.

tux@slitaz:~$  tazpkg search-pkgname lspci     

Search result for file : lspci
================================================================================
pciutils

================================================================================
1 pkg(s) found with file : lspci

This finds out if tazpkg containing file is installed.

tux@slitaz:~$  tazpkg search pciutils     

Search result for : pciutils

Installed packages
================================================================================
pciutils                3.0.3             system-tools

If you have trouble running these commands your shell may be broken.

i just reinstalled a copy of Slitaz. When I run the command " which Ispci" nothing happens. I ran the search command "tazpkg search-pkgname Ispci". Nothing comes up. It says 0 pkgs found with file: Ispci. However when I run the search for "pciutils" (version: 3.1,2), it is installed and to my computer. This is very confusing to me. I thought that Ispci pkg is already installed in the computer.

Sorry, I got the lspci command working ( I was just being stupid). Anyhow, I ran the command and this came up. "Vga compatible controller: Trident Microsystem Cyberblade/i7d (rev 5d). It didn't specify if it was a Agp/Pci/Isa card.

One detail i should add is that. The system i'm testing out is a laptop, therefore I cannot physically look at the connector. I want to know the bus, so i know if i need to install "linux-agp". Thank you for the help you brought me so far mojo.

Your welcome honmok.
AGP is a physical socket connection only on desktop motherboards with removeable graphics cards. On a motherboard or laptop with onboard graphics it's built in.
Run this command:

root@slitaz: tazhw detect-pci

See if slitaz detects any missing modules for detected hardware.
This told me missing module for intel agp

@mojo - but most of th older laptops use AGP - like all the IBMs like my X31

@homonk - just in case install it - when it is used, you see this in /var/log/Xorg0.log - if you will not find any notice about AGP there, you can uninstall linux-agp

@mojo - He was asking about the first l, which is an L not and capital I instead of the last i in pci.

@homonk - It's easier to remember the commands (lsusb, lspci, etc) when you take ls to stand for list and is similar to the ls command you use with listing the contents of directories. That's how I remember them anyway :)

@kultex: thanks for the information. I checked the spec of my laptop on the web ( sony pcg-f630), the bus it uses is agp but no other information like lanes (x1/x2) or version. I have installed linux-agp package. When i look at the log (Xorg0.org), the word "agp" is not on there. (search it with ctrl-f, just to be sure). It didn't seem like the northbridge was detected from the package (Via Apollo Mp4). Do I need to install some packages for the northbridge?

@Trixar_za: thank you too for telling me that is an "L" not an "I" after 30 times i tried typing the command. Nearly killed me. I really appreciate it :)!

Than you all of you guys

did you load the module?

modprobe intel-agp

I think, you have a intel processor ......
EDIT: no its a amd - so try.

modprobe amd-k7-agp

Should i changed the part K7 to K6 cause i know the processor is a K6? I'm pretty sure i loaded the module. I loaded with tazhw detect-pci. it says via_agp. I think it's loaded correct.

I tried that command it says
"modprobe: module amd-K7-agp not found"

its written here: http://doc.slitaz.org/en:guides:xorg-xvesa

All AGP video cards need extra kernel modules to function under Xorg. Check if you have an AGP video card with lspci; if so, install the necessary modules in the linux-agp package before using Xorg:

# tazpkg get-install linux-agp

Load the modules using the SliTaz hardware detection tool:

# tazhw detect-pci

You can now use the SliTaz X configuration tool to detect your settings:

# tazx

Select the appropriate driver for your video card from the list.

you have to install linux-agp, before you type tazhw detect-pci - the modul is present (Ichecked it).
After tazhw detect-pci you control with lsmod if the module amd-K7-agp is loaded - if not, you load it by hand with modprobe amd-K7-agp and report it here, because then its a bug in tazhw.

Please read the post above, I said that when lspci is ran it said:
Vga compatible controller: Trident Microsystem Cyberblade/i7d (rev 5d)
it didn't specify if it was using AGP bus. Anyhow im using Xvesa now, the performance is worse but whatever. Thanks for everyone who tried to help me.
