 Posted: Fri May 06, 2005 1:30 pm Post subject: No nvidia0 and nvidiactl with mm-sources-2.6.12.x |
 |
|
I've been having problems with the NVidia kernel module with the 2.6.12.x series of the mm-sources. Once I boot to it, re-emerge the kernel module and modprobe it, (which works fine, and yes my /usr/src/linux symlink is correct.  ), I don't get a nvidia0 and/or nvidiactrl in /dev.
If I revert back to 2.6.11.x and do the nvidia-kernel swap and reboot, it comes back and works fine. I tried compiling my kernel without agpgart (not sure what that does, but I thought it's helped in the past with NVidia issues), but that didn't work either.
Anyone else have this problem or have any suggestions?
edit...
I believe I've also tried both ~x86 and stable versions of the nvidia-driver.

Is this mm specific problem?
so my only option is to use other kernel? |

| well you could use the kernel patch and nvidia driver patch linked and use mm-2.6.12-rc4-mm2... its working here for me after applying them |

I just hit this problem yesterday after switching to 2.6.12-mm1 for some reiser4 testing (which btw rocks). I didn't know about those patches and just added a script into /etc/init.d/ and added it to the default runlevel to create those devices before X starts:
| Code: | #!/sbin/runscript
# Create nvidia devices
# nvidia currently broken with kernel 2.6.12-mm1/udev
#$ ll /dev/nv*
#crw-rw---- 1 root video 195, 0 24. Jun 2005 /dev/nvidia0
#crw-rw---- 1 root video 195, 255 24. Jun 2005 /dev/nvidiactl
depend() {
before xdm
}
start () {
if [ -e /dev/nvidia0 -a -e /dev/nvidiactl ]; then
eerror "NVIDIA devices already exist!"
return 1
else
ebegin "Creating NVIDIA devices (workaround due to broken drivers with kernel >= 2.6.12-mm1"
mknod /dev/nvidia0 c 195 0
mknod /dev/nvidiactl c 195 255
chown root:video /dev/nvidia0 /dev/nvidiactl
chmod 0660 /dev/nvidia0 /dev/nvidiactl
eend 0
fi
} |
Not very elegant, but it does it's job. |

So now this problem has landed in vanilla-land, with 2.6.13 (and actually some of the 2.6.12-rc's).
What's the right thing to do, besides creating the devices on every boot?!? Are there any official patches? |

the whole API has changed and it works just fine on 2.6.13 for me, presumably nvidia-glx creates the device nodes when loaded?
this is with version 1.0.7676

I'm stuck with 1.0.7174 since nvidia dosen't support my old card with their new drivers (mine is marked as legacy).
But it dosen't say in the nvidia-changelog that they should have fixed anything regarding the new API... |
