[gentoo-user] udev and nvidia

[Alexander Puchmayr]

Hi!

After upgrading the system and hence switching to kernel 2.6.13 and udev, my 
nvidia device nodes are no longer available and I did not find any way to 
create them automatically by udev.

According to http://www.gentoo.org/doc/en/udev-guide.xml, I have 
* nvidia listed in /etc/modules.autoload.d/kernel-2.6, and verified that it 
is loaded.
* media-video/nvidia-kernel-1.0.6629-r4 is installed 
* sys-apps/baselayout-1.11.13-r1 is installed

Additionally, I installed the coldplug package.

grep nvidia /etc/udev/rules.d/50-udev.rules
KERNEL=="nvidia*",      NAME="%k", GROUP="video"

Why is there no /dev/nvidia[0-7] and nvidiactl ? 
What did I forget?

Thanks for suggestions and greetings

I recall reading somewhere that because of the binary nature of the 
nvidia driver, you have to re-emerge it after building a new kernel.  
Seems like it was on a gentoo.org page about the nvidia driver.

Reemerge nvidia - it's one of the modules that when you rebuild the kernel you have to redo them.

I did this after installing the new kernel, and I re-emerged it again just 
to make sure, but it didn't help. Still, I don't have /dev/nvidia* created 
by udev, I have to create them by myself.

Doesn't work, sorry. Any other suggestion?

Thanks

I think this is because you're using an old version of the nVidia
driver, which isn't udev-friendly.

Doing this should resolve the problem:

(Note that # designates a root shell...)

# [ -z /etc/portage/ ] && mkdir /etc/portage
# echo media-video/nvidia-kernel >> /etc/portage/package.keywords
# emerge nvidia-kernel
# reboot

Instead of rebooting in the last line, you could also quit X and do:
# modprobe -r nvidia && modprobe nvidia

First of all, top posting sucks.

Secondly, you want the keyworded nvidia-kernel.

The problem is udev is not creating the device nodes like it should.  Neither
0.68, nor 0.70.   Why?  Don't know.

I took NVmakedevices.sh from an older nvidia-kernel (downgraded as part of
my troubleshooting the issue), saved it in /root, upgraded - 1.0.7676 removes it
and doesn't have it in the ebuild, and added to /etc/conf.d/local.start.

Yup, that's the problem - why I don't know either and searching didn't 
turn up any answers other than "it's broke".  I used the script to create 
them and it worked.
