I installed kde4 from slackware-current, and opengl does not work.

glxinfo gives :

XRender works but slowly.
How could I get opengl working ?

Thank you in advance.

Is your driver properly installed?
Does the xorg.conf have the right modules enabled/disabled?
There are many tips in the nVidia driver documentation that comes together
with the closed source driver.

I have the following xorg.conf :
