Comment # 22 on bug 925437 from Andres Nogueiras Melendez

Thanks for the answer.

Just remove all "messy" things, left from previous kernels and drivers,
so now the things that have changed are:

earth:~ # rpm -qa | grep -Ei "nvidia"
nvidia-glG04-361.28-23.1.x86_64
nvidia-gfxG04-kmp-desktop-361.28_k3.16.6_2-23.1.x86_64
nvidia-computeG04-361.28-23.1.x86_64
x11-video-nvidiaG04-361.28-23.1.x86_64

earth:~ # find /lib/modules/ -iname "nvidia.ko"
/lib/modules/3.16.6-2-desktop/updates/nvidia.ko

earth:~ # lsmod | grep -i nvidia
earth:~ # modprobe nvidia
modprobe: ERROR: could not find module by name='nvidia'
modprobe: ERROR: could not insert 'nvidia': Function not implemented
modprobe: ERROR: could not insert 'nvidia_uvm': Unknown symbol in module, or
unknown parameter (see dmesg)
mknod: missing operand after ���0���
Try 'mknod --help' for more information.

So now even worst, as the nvidia module does not load on kernel.

TTY consoles are fine, but no gfx enviroment. And from dmes
