Can't get 3D effects working [solved]


Recommended Posts

Can anyone help with this? I've just installed Mandriva 2009 Free on a new machine that has an nVidia 8400 GS video card. Mandriva installed the nvidia driver automatically through the MCC hardware screen. I've installed compiz and emerald. Unfortunately, MCC won't allow me to get the 3D effects working; it says that my system does not support 3D effects (I know it does). Any suggestions?

This is what I get:


$ uname -r


$ rpm -qa | grep nvidia








$ glxinfo |grep -i direct

direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)

OpenGL renderer string: Mesa GLX Indirect

You have everything installed that you need for that card. You could remove the nvidia-current-kernel-2.6.27-desktop-0.rc8.2mnb-177.70-1mdv2009.0 package if you no longer use that (2.6.27-desktop-0.rc8.2mnb) kernel. As daniewicz has already noted, you need direct rendering for the 3D effects. So please follow medo's instructions and see if that works for you.


Please let us know if you still have any problems.

Direct rendering needs to be ON, that is the problem.


Can you post the contents of your etc/X11/xorg.conf file?


The graphical server in MCC is set to "NVIDIA gforce 6100 and later".


Here is xorg.conf:

OK, but I'm not sure what to do exactly. I go to MCC>Hardware>Set up the Graphical Server. I see bars, "Graphic Card", "Monitor", etc. If I click on Graphic Card, it shows me a list of X servers. The one already highlighted is under NVIDIA and says "GeForce 6100 and later". Am I supposed to pick something else?
