More nVidia woes

Edweirdo · Posted: Tue Jan 28, 2003 6:43 pm Post subject: More nVidia woes

I have an nVidia Quadro4 700GLX. I had it running great under my LFS system (www.linuxfromscratch.org). I installed gentoo 1.4_rc2 and I can't seem to get the xfree to run. I emerged the nvidia-kernel and nvidia-glx (4196). I used the same configur[/quote]ation file from the LFS system and that doesn't work, I get a segfault. I tried to use XFree86 -configure and it said that my nVidia card was unrecognized. So I emerged xfree86 4.2.99 and the -configure worked, but using that configuration file gives me a "NVIDIA(0): unable to allocate config DMA context.". I've tried to merge the two configuration files but to no availe. I either get the above error (only appears at the console, not in the log) or I get a segfault. You can find my XF86Config and log below:

Hi edweirdo,

here's my config for xfree-4.2.1-r2 , nvidia-glx 1.0.4196 and
nvidia-kernel 1.0.4191-r1

You probably want to focus on the Module and Screen size sections.

Try doing a "modprobe NVdriver" as root.

For some reason it won't automatically load the nvidia module into the kernel for me anymore. I think it has something to do with that stupid f***ing "tainted kernel" message... You will get it when you modprobe, just ignore it.

I definately have the module loaded, that's not the problem.

Well edweirdo,

i do know one thing for sure and that is you shouldn't load dri, xtrap and record(see module section) at all when you're using the closed binary from nvidia.

Try commenting those lines first and see if that solves it.

I have the same problem. The weird thing is when i change:

Well, I added commented out the dri, record, and xtrap. char-major-195 is already in my modules.conf.

Something changed, though. I now get a black screen and on my console I have:

XIO: fatal IO error 104 (Connection reset by peer)( on X server ":0.0"
after 0 requests (0 known processed) with 0 events remaining.

There isn't anything interesting in my xlog.

I just don't understand why it works okay under LFS. I would hate to reemerge X as it takes so long.

the same thing was happening to me... my xfree86.0.log would report:

Fatal server error:
no screens found

just as your's does (i have a laptop with a Nvidia GeForce4 440 Go). i had a valid screen defined at 1600x1200, but it refused to work at this resolution after an upgrade to xfree. i decided to try something lower to see if i could get anything to work... i added 1024x768 to get:

I'm sorry folks. I've searched and searched (I swear) for days and still no luck resolving my problem, which is the same problem so many others have had. I did an emerge -u world last week. Ever since, the nvidia drivers fail with the dreaded "no screens found" error. I have read just about every relevant post. Here is a list of my attempts to fix.

1. recompiled the kernel with MTRR support.
2. made certain that I'm using 3xxx version of the ebuild.
3. tried to modprobe NVdriver. This gives me "insmod NVdriver failed".
3. unmerged and emerged nvidia-glx and nvidia-kernel several times.
4. re-emerged xfree.
5. emerge -u world again.
6. run xf86config a dozen times, and edited the XF86Config file twice that.

No luck. Not sure where to go. I know it's a dup post. I'm at my wits end, though.

chevymoon i think the modules name is nvidia not NVdriver at least that is what is in my modules.autoload and from lsmod?

It seems that some of us has this problem. But I cant figure out whats causing it.
My X ran perfect until i upgraded my motherboard and cpu.
And so i decided to reinstall gentoo with my new hardware. I keept my XF86Config and so on.
So in my guess is that it has something to do with the nvidia module. But im nog certain.
But a really weird thing (Ive mentioned this a couple of times) if I try startx about twenty times. My X may start.
So its up to all of the gurus to figure this one out. Cause im to stupied to do it. :wink:

Thanks, guys.

lsmod does not list any drivers, and modprobe nvidia says can't find driver.

chevymoon · Tux's lil' helper Joined: 07 Aug 2002 Posts: 112

expounding on that little revelation, does that mean my nvidia drivers aren't installed? I did an emerge nvidia-glx and emerge nvidia-kernel. Shouldn't that do it?

David_Escott · l33t Joined: 12 Jan 2003 Posts: 952 Location: Boston, MA

Chevymoon sorry about that aparently the name was changed with the move from 3xxx to 4xxx it is now called nvidia but for your drivers it is NVdriver. So nevermind I am just being stupid.

is /usr/sr/linux pointing to the tree where you current kernel is this is the most likely reason the module insertion would fail.

Are you using the kernel AGP drivers or the nVidia AGP Drivers?

David_Escott: I'm not sure, but I had not (until today, when I recompiled my kernel) done anything that I would think could affect my sources link.

Lares: I think I stumbled across something about being able to manipulate the xf86config file to select which AGP drivers are used, but I don't remember much about it at this point. Short answer: I don't know.

Thanks for your help.

Edweirdo · Posted: Tue Feb 04, 2003 3:38 pm Post subject: Got it running

I don't know what might have caused my problem, but I started over and it works fine now. I formatted my drive again and started the gentoo install from scratch. I had to get the xfree 4.2.99 to support my card, but it is working fine now.

Just as a wrap up. I got it working. I'm not positive, but I think the solution is the one described in the Nvidia troubleshooter guide thingy. I had tried to rebuild my kernel, but I'm pretty sure I didn't unmerge the Nvidia ebuilds first. So, I made certain that I unmerged those, recompiled the kernel, and (after some grub issues) re-emerged the nvidia drivers. Voila! Everything was copacetic (sic).

Thanks for the help, all.

I still havent got mine to work. Think you can try to tell what you have done to get it to work? Im getting more and more angry.

David_Escott · l33t Joined: 12 Jan 2003 Posts: 952 Location: Boston, MA

Well the basics are as follows.

Build a kernel.
reboot.
set /usr/src/linux to point to the directory of the kernel you just booted.
emerge nvidia-kernel
modprobe (nvidia for >=4xxx) (NVdriver for <=3xxxx)
check to see it loaded with lsmod
add to modules.autoload
emerge nvidia-glx
edit your XF86Config so that the driver is nvidia not nv, remove dri, glcore, add glx, use conservative settings first too ie: NVAGP=0, "RENDERACCEL" "false" etc
(I hope Im not forgetting anything)

tell us where you have problems.
