Direct Rendering will not turn on....

I'm trying to use the new nvidia drivers. I've trouble shooted them down to a point where they load fine. GLX is working. However direct rendering won't turn on no matter what I seem to try. When I try to run S2's game "Savage" natively an error message pops up in the game windows saying it could not allocate agp memory. The mouse pointer moves very slow and choppy in this situation. Here's some sample results of probing.

metallhead $ glxgears

1320 frames in 5.0 seconds = 264.000 FPS

1440 frames in 5.0 seconds = 288.000 FPS
1440 frames in 5.0 seconds = 288.000 FPS

My video card happens to be a GeForce4 Ti4200, 300fps is obviously not acceptable on a glxgears test... I need some help, I'm about dried up on ideas. Also you can find a copy of my xorg.conf file at ftp://metalhead.homelinux.net/xorg.conf

Looking over the directions in the nvidia README and your xorg.conf I think I may have found a problem. In the readme it says:

In the Module section, make sure you have:

Load "glx"

You should also remove the following lines:

Load "dri"
Load "GLcore"

but in your xorg.conf you have the following lines:
# This loads the GLX module
Load "glx"
# This loads the DRI module
Load "dri"

you need to comment or remove the line:

Load "dri"

Try that and let me know what happens.

you're right, I did over look the load dri. I had turned it on in my attempts to get direct rendering to enable. Unfortunately turning it back off did not seem to help out. I restarted the x server with the commented line. I took notice in the glxinfo that it was using mesa indirect renderer, but being unknowledgable to this sort of information, it has been rather difficult for me to come up with a conclusion.

And you have done

opengl-update nvidia

too? I don't mean to belittle you or anything, just checking

No, I have done opengl-update xorg-x11 as I use x.org

...see I get the feeling using Silicon Graphics and Mesa is the wrong idea when using nvidia hardware...

yeah but do opengl-update nvidia to switch to the hardware accelerated opengl libraries from nvidia. ur using the software ones from xorg.

metalh34d · Post by **metalh34d** » Mon Jul 26, 2004 4:34 am

the problem with that is when I do that I can't startx or access glxinfo/glxgears or start any games. The reason given is this:

System_Init()
Error: Could not open /dev/nvidiactl because the permissions
are too resticitive. Please see the FREQUENTLY ASKED QUESTIONS
section of /usr/share/doc/NVIDIA_GLX-1.0/README for steps
to correct.

...still no solution =/

the ftp site now includes a copy of my kernel config as well as a nvidia-bug report using its new script.

did the FAQ shed any light?

I would guess it's to do with

you know, after reading that once last night, one more time this morning after you suggested it... I woke up and came to my senses and used ctrl+w in nano to find the exact spot I was looking for without reading over it again... Anyway commenting out the lines in the file rebooting the xserver and running opengl-update nvidia did solve the problem, thanks a bunch!
