Hi fred,
Here's the steps that I struggled through to get my rage 128 set up in such
a way as to take full advantage of tuxracer. :-)
1. Install xfree 4.02. You've already done this.
2. Add the lines
deb http://people.debian.org/~warp/dri/ ./
deb-src http://people.debian.org/~warp/dri/ ./
to your /etc/apt/sources.list file.
3. apt-get install xlibmesa3-dri xlibmesa-dev-dri xserver-xfree86-dri
4. Edit your /etc/X11/XF86Config-4 file.
a) Add the following two lines to the end of the "Files" section:
ModulePath "/usr/X11R6/lib/modules-dri"
ModulePath "/usr/X11R6/lib/modules"
b) Make sure the following are all included in the "Module" section:
Load "dri"
Load "glx"
c) Make a section for your video card:
Section "Device"
Identifier "Rage 128"
Driver "r128"
VideoRam 32768
EndSection
d) Make your screen section point to the Rage 128 device:
Section "Screen"
Identifier "Default Screen"
Device "Rage 128"
...
e) Add a section (if you want) so normal users can use DRI:
Section "DRI"
Mode 0666
EndSection
5. Recompile your kernel. You need the following options:
# Build AGP Support as a module
CONFIG_AGP=m
# Find the appropriate section for your motherboard. Mine is the
# first one, yours may differ. Use the online help to find out.
CONFIG_AGP_INTEL=y
# CONFIG_AGP_I810 is not set
# CONFIG_AGP_VIA is not set
# CONFIG_AGP_AMD is not set
# CONFIG_AGP_SIS is not set
# CONFIG_AGP_ALI is not set
# We need DRM support, and DRM support for Rage 128:
CONFIG_DRM=y
CONFIG_DRM_R128=m
# Don't use FrameBuffer support. Not sure, but I've heard it
# screws things up.
# CONFIG_FB is not set
A couple of words about the chipset: I have an ASUS CUSL-2 motherboard,
which has onboard I810 video. I also have the Rage 128 in an AGP slot.
DO NOT select the CONFIG_AGP_I810, as that will enable the onboard
video, not the AGP slot video card.
6. Reboot with the new kernel. You should now successfully be able
to do the following as root:
# modprobe agpgart
Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 203M
agpgart: Detected Intel i815 chipset
agpgart: AGP aperture is 64M @ 0xf8000000
If you can't do this, you chose the wrong chipset for your motherboard.
Re-do step 5.
7. VERY IMPORTANT: I believe that the version of the Rage 128 kernel
drm module in the latest 2.4.x kernels is NOT the newest one
and has problems. At least, I had problems until I got a newer
one. (If this is incorrect, someone please tell me). To do this, go to
ftp://dri.sourceforge.net/pub/dri
and get the latest r128 drivers, for example, the file
ftp://dri.sourceforge.net/pub/dri/rage128-20010331-i386-Linux.tar.gz
Unpack it
# tar zxvf rage128-20010331-i386-Linux.tar.gz
Build it
# cd dripkg/drm
# make -f Makefile.linux
This should complete without error. Copy the resulting r128.o module
into your kernel module directory. For example,
# cp r128.o /lib/modules/2.4.2/kernel/drivers/char/drm/r128.o
This will overwrite the one provided by the kernel with the new
one. Now you should be able to load it:
# modprobe r128
[drm] AGP 0.99 on Unknown @ 0xf8000000 64MB
[drm] Initialized r128 2.1.5 20010308 on minor 0
8. Start X again. Important: If something didn't work, X will probably still
start, so you need to see if it worked.
a) Check /var/log/XFree86.0.log to see if there are any errors.
b) Run the command glxinfo. You should see some lines similar to
the following, plus some more:
OpenGL vendor string: VA Linux Systems, Inc.
OpenGL renderer string: Mesa DRI Rage128 20010321 AGP 1x x86/MMX
OpenGL version string: 1.2 Mesa 3.4.1
9. Install the program of your choice and run it!
# apt-get install tuxracer
# tuxracer
Enjoy. Hope this helps.
