Problem with nvidiafb after compiling kernel

donryanocero · 09-11-2008, 08:51 PM

I just compiled a new 2.6.26.5 kernel and seems to be working fine with the exception of the framebuffer. I changed the lilo.conf to VGA to get it to boot.

lsmod provides:

dmesg gave me:

I tried to modprobe it and I get:

Any ideas / suggestions?

Perhaps you missed something in the config steps?
Where did you get your '.config' parameters?

donryanocero · 09-11-2008, 09:24 PM

I started with the initial .config from the previous kernel and then used menuconf.

donryanocero · 09-13-2008, 06:47 PM

oh well. the VGA one works okay i suppose. :-o

perhaps i'll try again with the VESA

This might not be related to your problem, but if you have the
proprietary Nvidia drivers installed for X, nvidiafb will not work.

T3slider · 09-13-2008, 06:54 PM

You need to recompile the nvidia proprietary drivers after each kernel upgrade. Did you do this? (If not, just run the install program again)

Woops, should have paid more attention. Bruce is correct -- if you use the nvidia proprietary drivers, nvidiafb conflicts with them and must NOT be loaded. If you compiled nvidiafb INTO your kernel (which I suspect you did), you may have problems. I would suggest either excluding it entirely or at least making it a module.

donryanocero · 09-13-2008, 07:54 PM

So i just recompiled with it as a module (I think I did this previously)
Anyways. In the past I've never had to do more than

make modules
make modules_install

and all my modules worked. more or less.

Now the only modules that show when i lsmod are those pertaining to my sound card.

I'm not using the proprietary drivers in addition to nvidiafb.

With 2.6 kernels it's "make" and "make modules_install". But you still
need to copy your new bzImage to your /boot directory. Anything
that you built-in will not show up in lsmod. You can always grep
your config to check for support:

Code:

zcat /proc/config.gz | grep -i nvidiafb

for instance.
