SearchAndRescue
 
Hi,
I have Riva TNT M64 and recent kernel modules. When I try to play game SearchAndRescue, I just receive a message:
Unable to find useable X Visual.
Or with debug option set it writes:
GW Debug: glXChooseVisual(): RGBA double buffer X Visual not available.
GW Debug: glXChooseVisual(): RGBA single buffer X Visual not available.
GW Debug: glXChooseVisual(): RGB double buffer X Visual not available.
GW Debug: glXChooseVisual(): RGB single buffer X Visual not available.

The developer has written to me:
"As long as you have 16, 24, or 32 bits with a TrueColor
visual and a card that has an alpha channel, SAR should
find the appropriate X Visual."

I have a 16 bits color depth. Where is the problem?

check XF86Config
 
Do you Have Load "dbe" and Load "glx" in Section "Module"??
ex.
Section "Module"
Load "dbe"
Load "extmod"
Load "freetype"
Load "type1"
Load "glx"# Add this line
# And
# Remove or coment under lines
#Load "dri"
#Load "GLcore"
EndSection

And, Do you have any MesaGL library in /usr/lib or /usr/X11R6/lib?
They can conflict with NV GL library

Good luck

Yes, I have everything in XF86Config. I have xlibmesa3 instaled in both /usr/lib, /usr/X11R6/lib, but NV GLX has rewritten them when it was installing. Quake2 is working well.

Nvidia install /usr/lib/libGL.*
But if there is any libGL.* (not libGLU*) in /usr/X11R6/lib, they can conflict.

If QuakeII,III works well.. I don't know...
Perhaps TNT(1) is limited.

My TNT2-M64 doen't have S3TC(texture compression in OpenGL)

Have you tried if game works with Xfree (nv) and MesaGL?

I have RIVA TNT2 Model 64 as well. No I have not tried it with nv driver.
