[PlanetCCRMA] problem starting X

Wed May 30 20:09:51 PDT 2012

Hi 

I have just installed the planet-ccrma rt kernel on a machine running
x86_64 FC14. When I attempt to start X, I get the error message:

   Loading /usr/lib64/xorg/modules/drivers/nvidia_drv.so

   ...

   NVIDIA: Failed to load the NVIDIA kernel module. 

Previous posts to this mail list have indicated that I need kmod-nvidia

for my kernel. It seems that I don't have this:

   rpm -qa | grep -i nvidia

   ------------------------

   --> no modules found

   rpm -qa | grep -i kmod

   ----------------------

   --> no modules found

I then attempted to install the nVidia driver (is that what it needs?),

but the installation stopped with the message:

   There appears to already be a driver installed on your system
(version:

   285.05.33).  As part of installing this driver (version: 285.05.33),
the

   existing driver will be uninstalled.  Are you sure you want to
continue?

   ('no' will abort installation)

If I continue with the installation, it fails with the message:

---------------------------------------------------------------

   ERROR: Unable to find the kernel source tree for the currently
running

          kernel.  Please make sure you have installed the kernel source
files

          for your kernel and that they are properly configured; on Red
Hat

          Linux systems, for example, be sure you have the
'kernel-source' or

          'kernel-devel' RPM installed.  If you know the correct kernel
source

          files are installed, you may specify the kernel source path
with the

          '--kernel-source-path' command line option.

It appears as though I don't have the kernel source/devel rpm for the rt
kernel:

   rpm -qa | grep -i kernel 

   ------------------------

   kernel-headers-2.6.35.14-106.fc14.x86_64

   kernel-devel-2.6.35.14-106.fc14.x86_64

   kernel-2.6.33.3-85.fc13.x86_64

   kernel-2.6.35.14-106.fc14.x86_64

   abrt-addon-kerneloops-1.1.18-1.fc14.x86_64

   kernel-devel-2.6.33.3-85.fc13.x86_64

   kernel-devel-2.6.35.6-45.fc14.x86_64

   kernel-rt-2.6.33.13-149.rt31.2.fc14.ccrma.x86_64

   kernel-2.6.35.6-45.fc14.x86_64

Can anyone tell me what is wrong?

Before I installed the rt kernel everything worked on the machine

(I was using the nVidia driver and CUDA)

Below is some info about my system:

- the list of CCRMA rpms installed

- the error message in Xorg.0.log

- my file /boot/grub/grub.conf
