i cant run any program which need OpenGL

((
when i installed my MDK 9.1 everything was working fine.. i played FLIGHT GEAR....
i made reboot... AND NOW NOTHING IS WORKING !!!
when i run something in console i see error:
[root@localhost bin]# fgfs
GLUT: Fatal Error in fgfs: OpenGL GLX extension not supported by display: :0.0
if i run it from KONQUEROR its simple not runing...
i have installed:
NVIDIA_GLX-2.4.21.0.25.2tex-4496.i586.rpm
and some mesa-glut librares (needed by winex)
i have yesterday installed newest dirvers from nvidia but then i reinstalled system

(
those nvidia drivers can`t detect my kernel version (i have standard kernel from mdk 9.1)
but i installed them...
then i can`t run KDE or any X.... i saw "GLX not founded or something"
i tryed XFree86 v3 (becasue i used v4) and its NOT worked.. (even i dont installed nvidia drivers)
XFree86 v3 with 3D acceleration not work too!
any XFree86 v3 not work for me.. it says that it can`t detect my video card (i have geforce4 mx (64mb) tv-out) or that it cant run at current video mode...
WHAT I SHOULD DO???
