LKM conflict: nvidia vs. rivafb


I'm having some difficulty getting my NVIDIA kernel module to work (downloaded from nvidia.com). The installer tells me that the lkm conflicts with rivafb.o, and they will not work together. Here's what I've tried:

1) "rmmod rivafb.o": nothing happened.
2) "modprobe -r rivafb.o": nothing happened.
3) "mv rivafb.o .rivafb.o", followed by a reboot (the idea being I'd "hide" the module from the system): nothing happened.
4) recompile the kernel without rivafb support: hooray, NVIDIA works, but my /dev/dsp (sound) no longer works! "device does not exist"! WTF, mate?

Any suggestions??

I'm running Slack 10 and kernel 2.4.2.

Thanks!

Which graphics card are you using?

Have you issued
bash-2.05b# lsmod
I did and don't have a rivafb module in my system.

This comp has Slack-10.0 with kernel 2.4.26. The graphics card is a
nVidia Corporation NV34 [GeForce FX 5200] (rev a1) and when I install
the driver by issuing this
bash-2.05b# sh /DATA/Slack_save/downloads/NVIDIA-Linux-x86-1.0-6111-pkg1.run
I get the rivafb message. This has happened on at least 5 computers
where I've installed Slack-10.0, and did not happen with Slack 9.1.
If you just select OK at every screen through the install, it should be okay.

If you want further information on sound with Slack 10.0, check out this ->
http://jmccoy.sdf-us.org/slackware10/config/sound.php
Sound works fine after the initial install of Slack 10.0 for me, but when
I recompile the kernel, it's lost again. One time I got it back by using
the Slack install CD and copying the alsa driver file to /var/log/packages
and then installing it again with installpkg - a few other times that didn't
work. I need to recompile my kernel, and am looking for the sound
answer myself. It's out there...

My video card is an NVIDIA GeForce 4 MX 64MB.

My sound card is a SBLive! 5.1 digital.

I had absolutely no success reviving sound after I lost it... the way I got it back was by fdisking and reinstalling slackware altogether.

What do you mean by "I did and don't have a rivafb module in my system."

Thanks again...

still banging my head against the wall

Then all you need to do is what I posted before for the Nvidia module.
Just run the installer like it says in the Nvidia README - Text file on their
site, edit your /etc/X11/xorg.conf file, and you're all set. Ignore that
rivafb message...

Hate to hear that - that's the Windoze way, but sometimes it's easier than
searching and trying when there are many different ideas posted.

That's why I still have the default kernel, and I'm having to use a Realtek nic
until I recompile to use my BroadCom Gigabit nic. Please read the info at the
sound link I posted.

Well, I thought that was clear. Read it all in context...

Maybe someone else will post about the sound, or you can search
here in LQ and at www.google.com/linux for it's been asked about
lots of times.

The riva and sound modules are not conected so you must have changed something else during the compile - make sure you compile support for the sound card. And just check permissions on the /dev/dsp

BTW, do you see the saound card module load? Check dmesg... Any errors if it is loading?

Hold on... you reinstalled? Oops. Overkill

Hey amosf,

I'm not sure whom you're replying to - but in Slack 10.0 ALSA is
the default sound. With an install of everything except Games:
Code:
bash-2.05b$ find /var/log/packages -iname "*alsa*" -exec ls -l {} \;
-rw-r--r--  1 root root 3685 2004-09-02 03:06 /var/log/packages/alsa-lib-1.0.5-i486-1
-rw-r--r--  1 root root 1090 2004-09-02 03:07 /var/log/packages/alsa-oss-1.0.5-i486-1
-rw-r--r--  1 root root 14511 2004-09-02 03:06 /var/log/packages/alsa-driver-1.0.5a-i486-2
-rw-r--r--  1 root root 1769 2004-09-02 03:04 /var/log/packages/alsa-utils-1.0.5-i486-1
and this is my soundcard
Code:
bash-2.05b# lspci
omit other devices
02:0b.0 Multimedia audio controller: Creative Labs SB Audigy (rev 03)
02:0b.1 Input device controller: Creative Labs SB Audigy MIDI/Game port (rev 03)
and this is what's in the kernel for sound, omitting cards I don't have
Code:
# Sound
#
CONFIG_SOUND=m
...
CONFIG_SOUND_EMU10K1=m
CONFIG_MIDI_EMU10K1=y
...
CONFIG_SOUND_OSS=m
...
and sound is working. I did compile xmms-cdread-0.11d.tar.gz so XMMS would
read audio CDs. Other than that, it's "straight out of the box."

My board has a BroadCom Gigabit Ethernet nic, and in Slack-10.0 the kernel
has to be recompiled to use it (no module - tigon3 or tg3). When I recompile,
the first time I leave sound just as it is - and it doesn't work. I've also tried
several other options. But I never can get sound back. Probably just me, as
I'll be recompiling again in the next few days and will try the way I did it in
Slack-9.1; that is, leave CONFIG_SOUND=m and nothing else under sound,
then compile alsa-driver, alsa-lib, and alsa-utils from source. Then insmod
the modules according to the instructions at ALSA's site.

As far as the rivafb, there is a module in the 2.4.26 kernel for the riva framebuffer,
and the message appears when you install the Nvidia driver, but I've not had a
problem by just pressing OK and ignoring it. But I've only installed Slack-10.0
and the Nvidia driver on about 5 - 8 comps, so that's not a lot of examples.

Thanks for your help. Btw - didn't your sig used to say you run Slack?


Edit: Excuse me, for I wasn't intending to hijack this thread. I think
the discussion will benefit the thread starter, since his hardware, distro,
and kernel are similar. All Creative Labs SB cards use the same module,
except one Audigy which isn't supported at all.
