I am trying to get this little OpenGL program I wrote some months ago,
but this time it gives me this error (it compiles okay though):

$> ./mktrngdat
freeglut (./mktrngdat): OpenGL GLX extension not supported by display ':0.0'

I notice that there is some problem with Nvidia driver now adays and
module-assistant auto-install does not work for nvidia. So at present,
my system (Etch) is not using the proprietary Nvidia module, just the
native nv module.

Here are some of the related packages installed:
$> dpkg -l *free* *glu* | grep ^ii | gawk '{print $1 " " $2 "\t" $3}'
ii freeglut3 2.4.0-5.1
ii freeglut3 2.4.0-5.1
ii freeglut3-dev 2.4.0-5.1
ii freeglut3-dev 2.4.0-5.1
ii libfreebob0 1.0.3+svn443-2
ii libfreetype6 2.3.5-1+b1
ii libfreetype6-dev 2.3.5-1+b1
ii libglu1-mesa 6.5.2-7
ii libglu1-mesa-dev 6.5.2-7
ii ttf-freefont 20060501cvs-12


My xorg.conf file has the following parts:
Section "Module"
Load "i2c"
Load "bitmap"
Load "ddc"
Load "dri"
Load "extmod"
Load "freetype"
#Load "glx"
Load "GLcore"
Load "int10"
Load "type1"
Load "vbe"
EndSection
Section "Device"
Identifier "NVIDIA Corporation NV11 [GeForce2 MX/MX 400]"
Driver "nv"
BusID "PCI:1:0:0"
EndSection
Section "DRI"
Mode 0666
EndSection




Furthermore:
$> glxinfo

So, the questions is, how do I get my little program to work without
installing Nvidia driver?

I would try to uncomment the 'Load "glx"' line in your xorg.conf. You
probably commented out that line because the proprietary nvidia driver
requires you to do so, but AFAIK the "nv" driver does need the normal
Xorg glx module if you want to use the GLX extension.

Okay. I just tried that and from the Xorg log file I see that it being
loaded okay, but it is not being initialized:

I think the above error message means that your X is presently still
loading nvidia's glx module (which only works with nvidia's driver). The
nvidia-glx package overwrites the original Xorg glx module and uses
dpkg-divert to make sure that nvidia's glx module stays in place.
Purging the nvidia-glx package should give you the original Xorg glx
module back. Make sure you use "purge" and not just "remove" because
otherwise an initscript stays on your system which could cause trouble.
(I think this issue is fixed now, but it cannot hurt to be on the safe
side.)

That worked. Did "sudo aptitude --purge remove nvidia-glx", logged out,
restarted gdm and logged back in and glx worked. It is veeery slow
(understandably) but my OpenGL program runs at least.

BTW, I get this in Xorg's log file:
$> cat /var/log/Xorg.0.log | grep '(EE)'
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(EE) Failed to load module "type1" (module does not exist, 0)
(EE) AIGLX: Screen 0 is not DRI capable



If the second error a problem? Is trying to remove it worthwhile?

Easy fix. Just add this snippet to the end oc the xorg.conf.
