Quick AGP Question

Roguelazer · Posted: Wed Feb 12, 2003 12:24 am Post subject: Quick AGP Question

For some reason, my AGP does not work at all unless NvAGP is set to 0. This is the output of my "grep AGP /proc/pci":

I don't know if you have seen this before but there are many suggestions you can try here. I'm sorry I don't know what the answer is and I didn't see it in there when I gave it a quick glance, but it could still be in there.

I had same problem (black screen with little boxes), to fix your problem:

1) Either use : "NvAGP" "3" or comment out the line completely (i recommend commenting it)

2) In kernel config choose : compile agpgart and VIA VT82CXXX (or something like that...) into your kernel

And you will be good to go :lol:

Thank you for the information, I will attempt all of your ideas (particularly the kernel one) ASAP. It is nice to see such a good community, as my last distro seemed rather.... distant.

Hmmm... I have done what all of you suggested. Now I have an even stranger problem. When I type "startx" (With NvAGP set to 1 2 or 3), my screen fills up with random characters and a little red box in the upper left hand corner. Sometimes the little red box has a little green box inside it. Help! I want AGP!

If you use the agpgart support in kernel, dont use AGP in XF86Config. This is special setting('s) for Nvidia agpgart. And thus it will break if you have both. Because the driver will try to load Nvidia agpgart and you have kernel agpgart loaded.

Run "X -configure" and use that file without adding anything else than modes (Section Screen,SubSection Display) & VertRefresh, HorizSync (Section Monitor).

running "opengl-update nvidia" or "opengl-update xfree" will set the xfree server to use specified opengl subsystem.

# Summary
login as root
do X -configure (creates XF86Config.new in current dir)
nano -w XF86Config.new (adjust those settings)
save file to /etc/X11/XF86Config
# End Summary

If this dosn't solve the problem, plz do following.
Post driver version, kernel version, graphic card model&nr, monitor model&nr, motherboard model&nr/manufacturer, amount of RAM, agp adapturesize (setting is found in BIOS and possible values are 4,16,32,64,128,256). :wink:

err... I should change the new XF86Config to use "nvidia" instead of "nv", right?

yes you should and you should also put NVdriver in modules.autoload

Hmm... I have a GF4. X -configure won't recognize the card, it says something about me reporting the output of a scanpci. Oh yeah, and I use the 4191 drivers, so it's nvidia, not NVdriver for me.

hmm... i recall getting a similar message when i tried to run X -configure after i upgraded from xfree 4.2.0->4.2.1 when it worked fine in .0
if your desperate to use 'X-configure' you may have to downgrade but my recommendation would be to hack around with your existing config first before going through the trouble of downgrading...

also, might want to google for problems regarding your particular chipset, some agp implementations are real buggy and some have special fixes in certain kernels and some, well, just dont work in linux...

anyhow,
my $.02

You might also try xf86cfg xf86config.
The XF86Config file generated by the latter has a bunch of comments (too many for me) but works just great without any changes but the mouse section.
I'm using agpgart on the same chipset as yours, not mentioning NVAGP at all in the XF86Config.

X -configure or any other automatic config utility from XFree WILL NOT WORK with GeForce 4 cards as they do not recognize them.

You need to make your XF86config file by hand, here is mine to give you a head start (modify it to your needs, simply copying this WILL NOT WORK)

Aside from the fact that you have a module called record loaded, it looks the same as mine. I recently tried a lot in kernel with disabling, enabling and modularizing agpgart, I tried every nvagp setting, I even looked up my mobo online (it's the KT133, which is a modification of the KX133 built to work with the Socket A Athlon A-Birds. The KM133 is its sibling with integrated audio and video). I think AGP will never happen to me.

well i'm out of solutions bro... sorry

Hehe. Eventually I'll empty enough brains to get me an answer. Until then, well, at least it works with NvAGP 0.

hey,

so what happens when u comment out the nv line completly?
is your chipset support by agpgart?
what happens when u
cat /proc/drivers/nvidia/agp/status ?

and i assume it works when ur justing using the "nv" instead of "nvidia" in your xf86config?

ta.

sorry i didnt read peroperly, so agp is enabled thats good. i couldnt get mine to enable unless i forced try_unsupported for agpgart, nvagp doesnt work for me (SiS chipset...)

I just setup 2.5.63 kernel today yah! mayb agp will be better for me...
