xorg 3d acceleration for nvidia card

I've just noticed that 3d performances of my fx5200 256M nvidia card where far from being up to scratch. It's really slow.

I've done a dpkg-reconfigure xserver-xorg and except from the impression of having better font rendering, I can't see much 3d performance improvement. None at all actually. How can I test that the glx module is loaded ? opengl screen savers run ok, just very slow.

I know it is the nvidia driver that is being used. the nvidia-settings utility says direct rendering is not enabled. Is it the problem ?

Just noticed that in the Xorg.0.log file

Code:

(II) LoadModule: "GLcore"

(II) Loading /usr/X11R6/lib/modules/extensions/libGLcore.a

Skipping "/usr/X11R6/lib/modules/extensions/libGLcore.a:m_debug_clip.o":  No symbols found

Skipping "/usr/X11R6/lib/modules/extensions/libGLcore.a:m_debug_norm.o":  No symbols found

Skipping "/usr/X11R6/lib/modules/extensions/libGLcore.a:m_debug_xform.o":  No symbols found

(II) Module GLcore: vendor="X.Org Foundation"

        compiled for 6.8.2, module version = 1.0.0

        ABI class: X.Org Server Extension, version 0.2

(II) Loading extension GLX

I guess it's the root of the problem.

further down I found

Code:

==) NVIDIA(0): Backing store disabled

(==) NVIDIA(0): Silken mouse enabled

(**) Option "dpms"

(**) NVIDIA(0): DPMS enabled

(II) Loading extension NV-CONTROL

(EE) NVIDIA(0): Failed to load GLX

(WW) NVIDIA(0): Option "UseFBDev" is not used

any help fixing that would be most welcome.

Thanks in advance

go to your screen section under monitor put the backinstore on like this:

Monitor "Monitor[0]"
Option "BackingStore" "On"

this will make your window dragging not so noticable.

about the glx - try running the nvidia-bug-report.sh script from nvidia so you get some more info why it is failing.

and shouldn't the module be nvidia-glx that comes with the nvidia package?

Will do. the nvidia glx thing sounds like a lead.... Thanks

Well it wasn't. I think it's a recent break in the sid version of x.org cause I've just found a game I did play straight after installing my current video card and it played just fine. Now, even the introduction is slow.

Just have to wait for a fix. First time in a few years that sid deserve its 'unstable' tag for me....
