Some questions:
What Nvidia card do you have?
Do you have DRI enabled with the Nvidia drivers (load #DRI line)?
If you have: Does it help someway? What is your fps rate when DRI is disabled? Does the output of glxinfo change when it is disabled?
If you not: Do you get any errors when you enable it? Does the performance change?

Thanks for the answers.
I am going to compare it with my card results and maybe tweak mine card in some ways.

The mode 0666 is needed for all chips to let users have acceleration.

Ok well I have been trying to follow this thread's instructions as much as possible, and I am still having no luck enabling DRI on Slackware10.2 I have an ATI Radeon7500 chipset, and so downloading the ATI drivers won't work, since ATI does not support anything below 8500 chipsets. Also, I don't know why this isn't working for me, because this is exactly what I did in Slackware 10.0 to enable DRI, which worked by the way ... And this is my xorg.conf

Code:

# This loads the GLX module
    Load       "glx"
# This loads the DRI module
    Load       "dri"

Section "Device"
    Identifier  "Radeon"
    Driver      "radeon"
    VideoRam    65536
    # Insert Clocks lines here if appropriate
EndSection

 Section "DRI"
    Mode 0666
 EndSection

Output of glxinfo:

And Xorg.0.log with all the (EE) that are listed, actually, no (EE) messages found, only (WW)

Code:

(WW) Open APM failed (/dev/apm_bios) (No such device)
(WW) RADEON(0): Failed to detect secondary monitor, MergedFB/Clone mode disabled
(WW) (1792x1344,GatewayVX700) mode clock 204.8MHz exceeds DDC maximum 180MHz
(WW) (1856x1392,GatewayVX700) mode clock 218.3MHz exceeds DDC maximum 180MHz

Any suggestions on what I should try now?

cwwilson721 · 04-08-2006, 12:29 PM

Try logging on as root,(Disconnect from the internet first if you're worried about security.), and see if that changes anything in glxinfo. It may give us a clue.

***EDIT*** Are you using init 3 or 4? I've personally run into weird stuff in init 4 like that..

Jeebizz · 04-08-2006, 12:39 PM

Same thing, no DRI as root either. I also rmed the Xorg.0.log before starting an x session, and it is all the same, no EE messages, just the same WW messages as before. glxinfo says the same thing, no dri, nothing has changed. I am using the default init by the way.

cwwilson721 · 04-08-2006, 12:43 PM

Do a grep on Xorg.0 log for Direct or dri. See what it says. Do you have the chipsets, agpgart, and video chips compiled as modules in your kernel?

Jeebizz · 04-08-2006, 12:51 PM

Well I am using the default 2.4.31 kernel, I haven't recompiled it, and agpgart are compiled as modules, because lsmod reports agpgart, along with my radeon module.

Code:

Seems like no DRI because of the driver.

Anybody have any ideas on the radeon driver?

Old_Fogie · 04-08-2006, 01:20 PM

Yeah I don't know what you do for old cards. That XFreeX6 stuff was before my time with Linux.

I'd be interested to find out tho as I was thinking of picking up an old card to thro into an old pc here to act as a linux router (one of my many projects to keep me up all nite).

Have you tried going thru this WIKI here: [HTML]http://dri.freedesktop.org/wiki/[/HTML]

That's who ATI claims the 3d for older cards is supported by.

Oh another thought off the top of my head, but have you tried one of the boot cd's like slax and mutagenix. Their slack based and have some really good hardware detection. I'm wondering if loading up your pc off one of those boot cd's, trying glxinfo and seeing how they load for you.

Also I belive Mepis Lite is based on xfree86 if I'm not mistaken. I downloaded so many distro's omg I'm getting em confused, but I think that booting up one of those guys might help to see what to do on slack.

But again I'd like to see what you do, as my old laptop right now does not do DRI but does have support from linux kernel w/the video driver and I've seen claims from people on old threads that it can. But I havent had a chance to get into that yet to date.

Old_Fogie · 04-08-2006, 01:28 PM

cw..you get 6000 fps! w/onboard video...wow I really need to upgrade!

Jeebizz · 04-08-2006, 01:30 PM

Ok, well I tried that site again, and downloaded this file: radeon-20060403-linux.i386.tar.bz2 , since it is the only other radeon snapshot that I could think of, r200 snapshots are for 8500+ cards, so I am assuming this is for older ATI cards. Any pointers on how to install this driver? Still I am puzzled on why I have to do this, since under 10.0 using the same generic driver I got DRI to work. Oh well

[edit]

Assuming after installing this driver, will I have to rerun xorgconfig, and will it show up in the list?
