| One of the other discussion threads suggested that the device would probably disappear at the next boot, but if you can suggest how to create the device, I will try it. |

| Code: | mknod /dev/nvidia0 c 195 0
mknod /dev/nvidiactl c 195 255 |
This is not tested, and you should check permissions and ownership after creation, below are nodes from my system:
| Code: | crw-rw-rw- 1 root root 195, 0 May 29 19:01 nvidia0
crw-rw-rw- 1 root root 195, 255 May 29 19:01 nvidiactl
|
Refer to man pages and Google if in doubt. I'm sure there is a way to make them survive reboot.

I created the devices as you specified, and they do get deleted on reboot. I also tried creating /dev/nvidia. That didn't work either.
When I tried to do a "modprobe nvidia" on the device, I get the following error message:
| Quote: |
WARNING: All config files need .conf" /etc/modprobe.d/alsa.conf.def, it will be ignored in a later release.
Error inserting nvidia (/lib/modules/2.6.39-gentoo/nvidia.ko) no such device
|
nvidia.conf is in /etc/modprobe.d/, by the way. |

Well that means that nvidia kernel module is not installed for the kernel that you are running. Did you switch the kernels ?
Or your /usr/src/linux does not point to the right kernel. Check it, and do emerge nvidia-drivers again. |

nvidia.ko is the driver (it should be in /lib/modules/<kernel ver>/video), and if it does not exist then it certainly won't load.
does "emerge -v nvidia-drivers" complete successfully

OK, here has been some confusion. Let's sum it up.
This thread is about nvidia node that is not created, thus running X is not possible.
This is happening even after nvidia drivers are compiled against kernel sources in use.
Manually creating device nodes does not help, even after nodes are created X will not run (no reboot).
Is all this correct?

the device nodes will never get created if the module is not loaded.
According to a previous message
| Quote: | | Error inserting nvidia (/lib/modules/2.6.39-gentoo/nvidia.ko) no such device |
it is not finding the module to load (from this messages it is looking in the wrong place)

| That's what I'm (pretty sure I'm) seeing. I agree, though. It sounds shaky. |

Now the question is why is it looking for nvidia.ko in /lib/modules/2.6.39-gentoo/ instead of /lib/modules/2.6.39-gentoo/video/
What does "grep nvidia /lib/modules/2.6.39-gentoo/modules.dep" return?

gentoo is running as a text device, so I am communicating with you from a kubuntu system on the same computer. I wrote the error message on a piece of paper and did it wrong.
The message is
"Error inserting nvidia (/lib/modules/2.6.39-gentoo/video/nvidia.ko) no such device."
Sorry.

it acts like it's not seeing the nvidia hardware or you've got another driver in the way
what does "lspci -kk|grep -A4 VGA" return (it should be 4 lines of output)

Sorry: Another problem with trying to run from kubuntu:
The actual lspci -kk|grep -A4 VGA gave a line:
Kernel Driver in use: nouveau.
Back in ancient history I had nouveau blocked. How do I block it in the new baselayout-2? |
