xorg can't see the nvidia module

kwiqsilver · Guru Joined: 19 Mar 2003 Posts: 360

I have the nvidia module loaded (and I'm quite sure it's the right module for my kernel, because it shouldn't load otherwise), but when I run startx, I see this:
(EE) Failed to load module "nvidia" (module does not exist, 0)

even though I have the module

Can we see the output of dmesg?

I get the same error. Help, please...

Drysh · Posted: Thu Feb 16, 2006 7:10 pm Post subject:

try:
/sbin/NVmakedevices.sh
This will create the device to access the card.

BTW: now I can enter X, but (i don't know why) it doesn't load anything (no session). Can anyone help me?

I have no such file (/sbin/NV*)

I can't get it working. This is my emerge info, make.conf, nvidia versions and x server -config and -log.

those who dont have the NVmakedevices.sh script should ls -la /dev/nv* and make sure they are there - see below on what mine now looks like.

somewhat good news....one problem solved but another one surfaced:

I am not sure which one solved the problem....cause I did two things before checking startx.

First, I added the masked udev to my /etc/portage/package.keywords and emerged it.

Second, hearing a lot of people talk about a gentoo specific file /sbin/NVmakedevices.sh but it didn't exist on my system, I searched for it on google and found it. It seems in was included in 1.0-6629 but must not have been in later versions. After running it, I had:

# ls -la /dev/nv*
crw-rw-rw- 1 root root 195, 0 Feb 17 23:16 /dev/nvidia0
crw-rw-rw- 1 root video 195, 1 Feb 17 23:16 /dev/nvidia1
crw-rw-rw- 1 root video 195, 2 Feb 17 23:16 /dev/nvidia2
crw-rw-rw- 1 root video 195, 3 Feb 17 23:16 /dev/nvidia3
crw-rw-rw- 1 root video 195, 4 Feb 17 23:16 /dev/nvidia4
crw-rw-rw- 1 root video 195, 5 Feb 17 23:16 /dev/nvidia5
crw-rw-rw- 1 root video 195, 6 Feb 17 23:16 /dev/nvidia6
crw-rw-rw- 1 root video 195, 7 Feb 17 23:16 /dev/nvidia7
crw-rw-rw- 1 root root 195, 255 Feb 17 23:16 /dev/nvidiactl

Initially all files were owned by root:root but I noticed the udev rules wanted root:video so I modified the script above....I don't know why it didn't make nvidiactl root:video...and I just now realized it so it may fix my next problem. I also dont know why udev is not working to create the devices...

SOLVED --- New Problem - after I startx, I lose all F1 - F6 consoles and am unable to ctrl + alt + F1 - F6 to get to a shell. (this was caused by using vesafb and not vesafb-tng. Once I switched to vesafb-tng the problem was fixed)

I appreciate everyones help and suggestions and now I really feel bad that at least the first problem was caused by a misconfigured system and not anything related to nvidia modules.

see my post here for the correct way to create the nvidia devices using nvidia-kernel and nvidia-glx higher than 1.0-6629

My problem never where missing nvidia device files. I guess it where trails left after my attempt to try out xgl and updated to modularized X.org (7). I upgraded again to the "unstable" modular X.org and ~x86 nvidia-kernel module loads fine once again.

Not really a solution, but it works OK for me at the moment.

I had a similar problem when I switched to a 2.6.15 kernel. Using the masked nvidia-kernel and nvidia-glx got me going again.

I read this thread and the link provided, but the tips didn't work. I ended up downgrading to gentoo-sources-2.6.14-r5 (x86), using the latest stable nvidia-kernel/glx (1.0.6629-r5), upgrading to the latest stable udev (084, as this "no /dev/nvidia devices" problem is udeb-related), and editing /etc/conf.d/rc to change RC_DEVICE_TARBALL="no" to "yes".

Sad, but that's the only non-hackish way I've discovered to get my system to remember the /dev/nvidia* devices at startup. Otherwise, all the /etc/modules.d/nvidia tinkering still wouldn't create the devices at startup. I understand that it should when I run "startx", but I prefer to have gdm start once my system finishes booting. Besides, even manually running "startx" with the modules.d/nvidia options doesn't work.

Try upgrading to the latest ~x86 udev and latest stable nvidia-kernel, *not* running 2.6.15 (which still won't work for me at least), and resetting RC_DEVICE_TARBALL to "yes" and then reboot. Possibly reboot twice; took a couple of boots for me, but now is reliable.

Still wish the nvidia/udev packages would get together on this and cooperate.

It shouldn't. I took out those configuration lines from /etc/modules.d/nvidia entirely, since they didn't work. Now that the file is back to the defaults, everything works.

I'm using the 8178 drivers (XGL attempt), and noticed the permissions swtich. It is killing my ability to run XGL. It is also borking normal GL programs under normal X. If I go in AFTER the server has started and modify the permissions:

chown root:video /dev/nvidia*

everything works great. Otherwise, I'm stuck. I tried the advice to use the "options nvidia NVreg_*" settings in /etc/modules.d/nvidia, but it didn't seem to have any effect.

Anyone else seeing this? Suggestions on how to fix permissions when X starts up?

THANKS A LOT!

~x86 udev +
~x86 nvidia-kernel +
~x86 nvidia-glx
