livna nvidia libglx.so = blank screen, xserver waits

[bryanl]

is there a way to get livna libglx.so to 'just work' (FC6, kernel 2.6.22.5-49.fc6)
when i load the livna nvidia libglx.so , the xserver waits showing a blank screen and this in the Xorg.0.log:
---->8------
(II) LoadModule: "glx"
(II) Loading /usr/lib/xorg/modules/extensions/nvidia/libglx.so

Backtrace:
-------- end of Xorg.0.log --------
... then i have to Ctrl-Alt-F1 or Ctrl-C to kill the server, at which point i just use the backup xorg.conf and the server restarts OK.

the xorg libglx.so works fine. so the difference is the livna nvidia module. i basically did this in order:
yum update kernel
-> 2.6.22.5-49.fc6, i686 (NOT i586 - known to be bad - google this)
yum install kmod-nvidia-96xx
-> installs kmod-nvidia-96xx and automatically pulls in xorg-x11-drv-nvidia-96xx

i then hacked/flailed a lot to get an xorg.conf that 'just works', but i think its alright by the Xorg.0.log. includes running system-config-display, nvidia-xconfig, nvidia-settings, and finally decided to issue:

nvidia-config-display disable

... so at that point, i lost track of what these things were doing besides updating xorg.conf. i THINK i let yum do everything with loading modules or whatever ; i KNOW that i did NOT use anything available from nvidia.com. all this is from multiple login/out, startx's, etc., so i had the original simple question b/c i seem to be stuck at that libglx.so 'not working'. in case someone asks about FC7 upgrade, well, i was hoping to get by without, since its easier overall in my case.

more details:
lsmod gives:
nvidia 4719284 16
i2c_core 27841 2 i2c_viapro,nvidia

dmesg says:
nvidia: module license 'NVIDIA' taints kernel.

oops - forgot :
with the xorg libglx.so loaded, we get :

glxgears
X Error of failed request: BadLength (poly request too large or internal Xlib length error)
Major opcode of failed request: 144 (NV-GLX)
Minor opcode of failed request: 3 ()
Serial number of failed request: 8

glxinfo

does livna's nvidia libglx extension conflict with libnvidia-tls.so.1 ?
does livna provide libnvidia-tls.so.1? it is located in /usr/lib/nvidia - something from an old nvidia installation i think. it was in ld.so.conf, so i removed it, yet i get :

(II) LoadModule: "glx"
(II) Loading /usr/lib/xorg/modules/extensions/nvidia/libglx.so
dlopen: libnvidia-tls.so.1: cannot open shared object file: No such file or directory
(EE) Failed to load /usr/lib/xorg/modules/extensions/nvidia/libglx.so
(II) UnloadModule: "glx"
(EE) Failed to load module "glx" (loader failed, 7)

glxinfo is different, but alas no glx extension:
Xlib: extension "GLX" missing on display ":0.0"

... i.e. when X cannot read /usr/lib/nvidia/libnvidia-tls.so.1 but has /usr/lib/xorg/modules/extensions/nvidia in ld.so.conf, libglx.so can't load for some reason - why?

when /usr/lib/nvidia AND /usr/lib/xorg/modules/extensions/nvidia are both in ld.so.conf, i get the 'waiting X server' result, without error messages (says 'Backtrace' only in Xorg.0.log).
