Cannot Enable Desktop Effects on CentOS 6

Hi,

I am running CentOS 6 on a Dell Precision M4300 and I cannot enable Desktop Effects. When I try to enable it I get "Accelerated 3D graphics is not available. Desktop effects requires hardware 3d support."

I am gathering it's probably a driver issue as I've poked around for quite a while on Google now trying various solutions for creating a new xorg.conf file, reloading Nvidia drivers, unloading nouveau, etc but I haven't had any success yet. Here is the output of lspci:

Code:

And the output of lsmod if it helps: 

[root@localhost ~]# lsmod | grep video

video                  16662  1 nouveau

output                  1779  1 video

[root@localhost ~]#

I currently have no xorg.conf file and when I try to create one I get the following:

Code:

[root@localhost ~]# Xorg -configure



Fatal server error:

Server is already active for display 0

        If this server is no longer running, remove /tmp/.X0-lock

        and start again.





Please consult the Red Hat, Inc. support 

        at https://www.redhat.com/apps/support/

 for help. 



[root@localhost ~]#

So then I drop to init 3 or init 1 and try again and I get an error about the PCi device being held hostage by the kernel. That's why I tried to unload nouveau and couldn't get anywhere with that either. I'm stumped.

All I want to do is enable desktop effects so I can use the cube desktop.

Any input?

Thanks!

You can use also nv driver instead nouveau, or proprietary nvidea from here http://www.nvidia.com/Download/index.aspx?lang=en-us, or from distribution repository. For your graphic card it seems be NVIDIA-Linux-x86-285.05.09.
But I don't sure that it solves problem. All drivers for nvidea under linux are imperfect. They can not enable some hardware ability. It is missing not of Linux, but of NVIDIA Corporation, which itself can not manufacture a good driver for Linux, and does not discover source code.

My more old nvidea Geforce FX 5900 XT also does not support graphical desktop effects and 32-bit color management, with any drivers.

There is official specification of support OpenGL in nVidea http://developer.nvidia.com/opengl-driver
here a criticism of NVIADEA Corp. policy toward Linux http://jeffhoogland.blogspot.com/201...pport-for.html

Nvidia proprietary driver WILL work.

If you look at Fedora 16 bug reports, you'll see that the 'open' driver stack (nouveau, mesa, etc.) only became capable of doing "everything" required by Compiz, and KWin, just a few days ago. A recent kernel update is necessary, too.

So, unless you want to be an alpha tester; switch to Nvidia's proprietary driver -- even though it probably won't be compatible with Qt on Wayland in the future. :(( !!!

When you switch to Nvidia's proprietary driver, be sure to blacklist any nouveau and mesa modules wshich appear in 'lsmod' output. Even though it doesn't support 3d, you should back up your xorg.cong file before allowing the NVidia installer to mess with it, their 'save the old one' only saves one copy. (So, if it dies the first time, and you run the Nvidia Installer a second time, your pre-Nvidia configuration is destroyed. Do NOT save under the name 'xorg.conf.old', that's the name which Nvidia will overwrite if it already exists.)

If Centos has an NVidia package, just use that- it saves you the trouble of installing the Kernel 'Development' Source Headers form the Nvidia Driver compilation step. But both ways work, it's not hard to do either way.
