Very Computer

I enthusiastically installed Xfree4.0, as I now have a
Voodoo3-3000 AGP card with 16MB RAM on board. Everything seems to
work, but 3d rendering was slow as before, and when I ran 'glxinfo'
it told me that I'm only using Software Rendering:

OpenGL renderer string: Mesa GLX indirect

I use Xfree86-4.0 with the tdfx driver and the glx and dri
modules loaded, on Linux-2.3.99-pre2 with the tdfx and agpgart module
loaded, in the X-server log it says 'direct rendering enabled', I
have 1152x900 screen resolution with 16bpp depth, xdpyinfo show the
necessary extensions are loaded,  what's more ?

I'm sure I checked all the points that were on this DRI Users
Guide (http://www.xfree86.org/4.0/DRI.html), and it still doesn't
work. I also havn't set any environment variables that force Software
rendering, so where's the problem ?

PS: I don't have the logs here at work at the moment, but
    if nobody has a tip I could post the Xfree-log, the
    output of xdpyinfo, the /sbin/lsmod output and the
    glxinfo output.

I'm following up myself (-:
By Mail I received a tip to set the LIBGL_DEBUG variable. Then, the
problem became appearent: it wasn't finding the libglide3.so.3...

Either there is a bug in the documentation or I misunderstood it, as
I read that libglide is obsolete and only needed for voodoo1 and voodoo2
cards. With the voodoo3, the hardware is accessed directly by the tdfx
driver... So I didn't install libglide.

Now (almost) everything works, I have 58 fps with the teapot demo in a
1024x768 window !

There are just 2 little points: Xfree4 crashes my EIZO Flexscan F55...
With crashing I mean, I can't access the onscreen menu anymore and the
image is not centered. Then I have to switch off the monitor and switch
it back on. Then it works perfectly, until I end X and restart it,
then I have to restart the monitor, too... Strange thing..

The second point is a question: In linux 2.3.99-pre2 I found a module
called agpgart, which is for accessing the AGP port. I insmoded this
module, but lsmod shows that it isn't used. Is that normal ?
(I have the AGP version of the voodoo3)

Is your X-server configured to use agp? I haven't started using the pre-kernels yet (i use 2.2.14 currently and tested 2.3.42) so I'm just guessing... I know that there is some agp-config in the site.def (or was it linux.def?) in the source-tree...

Best regards

I first didn't use the modelines, but then, I didn't have 1152x900, but
only 1024x768 or 1280x1024. I wanted something between, because with
1280x1024, the refresh rate was too low (75 Hz), and 1024x768 is too
small for a 17' Monitor.
I will try disabling the DDC stuff, maybe that will solve the problem.

I don't think, as I downloaded the binaries. Maybe I have to recompile
with the proper options. Is the documentation about that ?
