[SOLVED] xorg+nvidia: "Failed to load module dri"

trepanne · n00b Joined: 23 Aug 2003 Posts: 35

I've got this box with an nvidia Quadro NVS 420 card (dual GPU, four video outs). I had the whole thing set up correctly under OpenSolaris. Now I've wiped off osol & am trying to get Gentoo running on the same hardware, but it's not working. This is a new installation; no xorg upgrade issues.

In the kernel, I've configured module loading and MTRR support; I've turned off nvidia framebuffer.
The kernel I've built is linux-2.6.31-gentoo-r6.
The /usr/src/linux symlink is pointed correctly, and gets picked up as such by "eselect kernel list".
In /etc/make.conf, I've set INPUT_DEVICES="evdev mouse keyboard"; VIDEO_CARDS="nvidia nv".
I've installed xorg-server-1.6.5-r1, and nvidia-drivers-190.42-r3.
Using the eselect tool, I've set the OpenGL to use nvidia's implementation.

If I try issuing "startx" without any xorg.conf, the system locks & needs a hard reset. I get the same behavior if I load an xorg.conf generated by X itself.

If I use the same xorg.conf that was working for me successfully under solaris, or a fresh xorg.conf generated by nvidia's script for doing so, then X fails to start, issuing errors that it "failed to load module dri" and "failed to load module dri2", because neither can be found. I've tried inserting a "Module" section in xorg.conf, not loading any DRI, but alas, the behavior remains the same.

Looking through XOrg.log, HAL seems to be detecting my input devices nicely, and I get all sorts of debug output indicating that the nvidia driver is doing its thing and understanding its configurations. It just seems to be this bit about the DRI. What am I doing wrong?

I'll reproduce below my xorg.conf which worked under osol, which I'm trying to reuse under Linux. It's cleaner than the one auto-configured by the nvidia utility.

TIA

trepanne,

The nVidia binary blob does not use dri or dri2, so those errors can be safely ignored.
It does its own thing for direct rendering.

Change your Section "ServerLayout" to use a single screen until we get nvidia working.
The log is more useful than the xorg.config.

Does it work? Or does it deadlock again?

Something similar happened to me when I got my new computer, a few weeks ago. I lost my notes but I remember that I tried nv, vesa and vga modes without success. I remember very well that I succeded only after I emerged and configured x11-wm/twm

( I just learned that twm ins't included anymore in the xorg-x11 ebuild... ) Can't remember what mode I used at the time but it's easy to test. Give it a try and see what happens! Best of lucks!!!

Is this a old box?

I have a web page that shows most of the nvidia cards and I can not find the one that you have listed in your post.

trepanne,

It looks like Xorg started normally, found nothing to do, then quit.

What window manager do you have installed?
Do you get errors about twm, xterm and xclock are not found ?

I think he just did:

X

If X is executed like that, it won't quit untill you kill it (or CTRL+ALT+BACKSPACE).

Besides, I got xinit with the minimal useflag (no twm, xclock etc) and everything works fine.

Yes, this sounds right. No window manager.

I just installed xorg-server (not xorg-x11), and I do indeed get errors about not finding twm, xterm, and other commands inside /etc/X11/xinit/xinitrc.

I have installed KDE4, and would like to use kdm. I've placed XSESSION="KDE-4" in /etc/rc.conf, but that's not doing the trick. What do I need to do?

Thanks for the help gentlemen.

whiteghost - thanks. I did as you wrote, and then started the xdm service with /etc/init.d/xdm start. kdm started right up & posted the graphic login screen (even though I was already logged in).

So I guess it's intended that I should further say rc-update add xdm default, and do my logins that way?

I think that's probably good enough. Thanks are particularly due to NeddySeagoon & whitegost.

But as long as I'm digging in here, how do I get kdm to start if I want to do CLI logins and start the GUI with startx (or another means)?

Thanks guys, you're really helpful.

don't think you need xdm default. actually xdm is another package probably not installed.
from login screen there should be a button for options / configuration to set autologin. i use gdm.
from command line

i just emerged xdm.
rc-update add xdm default
edited /etc/conf.d/xdm
to
DISPLAYMANAGER="gdm"
and everything is auto now.

So, do you see something or you still have a black screen ?

Now that you have at least a Screen, we will try to make your dual screen working

I'll just mark this resolved, then.
Thanks guys.
