[gentoo-user] Failed to load driver: Nouveau

[IceAmber]

Hi, everyone

There is an error in my system, it print as follow when I run the command `glxinfo | grep AGP`

iceamber@localhost:~ $ glxinfo | grep AGP

nvc0_screen_create:944 - Error allocating PGRAPH context for 3D: -22

libGL error: failed to create dri screen

libGL error: failed to load driver: nouveau

Here is the Xorg.0.log 

The model of my graphic card is GTX1060, and the kernel version of my system is linux-4.12.5

is there any suggestion for me?

 

 

Thank you & Nice Weekend
Ice Amber

Did you eselect opengl and mesa?

[Adam Carter]

yes, here is the eselect

When i have X problems i can resolve i run emerge -av @x11-module-rebuild xorg-server mesa but its generally an act of desperation after running out of intelligent options.

[IceAmber]

I have tried, but the same result

[Alexander Kapshuk]

Your xorg-server was built for kernel 4.9.34.
[ 24.014] Build Operating System: Linux 4.9.34-gentoo x86_64 Gentoo
[ 24.014] Current Operating System: Linux localhost 4.12.5-gentoo
#10 SMP Sat Aug 26 13:15:20 UTC 2017 x86_64

Might be a good idea to rebuild x11-base/xorg-server for your current kernel.

What's the output of the command lines below?
grep NOUVEAU linux/.config
grep -E 'nvidia|VIDEO_CARDS' /etc/portage/make.conf

[Alexander Kapshuk]

This one too please:
grep -si nouveau /var/log/*

Also, let's make sure mesa has the USE flags below enabled:

equery -q u mesa | grep -E 'gallium|nouveau'
+gallium
+video_cards_nouveau

[IceAmber]

iceamber@localhost:~ $ grep NOUVEAU /usr/src/linux/.config

CONFIG_DRM_NOUVEAU=m

CONFIG_NOUVEAU_DEBUG=5

CONFIG_NOUVEAU_DEBUG_DEFAULT=3

CONFIG_DRM_NOUVEAU_BACKLIGHT=y

iceamber@localhost:~ $ grep -E 'nvidia|VIDEO_CARDS' /etc/portage/make.conf

VIDEO_CARDS="nouveau"

here is the `grep -si nouveau /var/log/*`

I have rebuilt the xorg-server, it is built for kernel 4.12.5 now.

And I have set the USEs of "gallium" and "video_cards_nouveau"

[Alexander Kapshuk]

I'm not seeing these errors in your Xorg.0.log any more:
[ 25.361] (EE) AIGLX error: Calling driver entry point failed
[ 25.375] (EE) AIGLX: reverting to software rendering

Are you still getting the error message about the nouveau driver not
being loaded when running glxinfo or glxgears?
If you are, what's the output of:
lsmod nouveau
modinfo /lib/modules/`uname -r`/path/to/nouveau.ko

Note: 'path/to' in 'modinfo /lib/modules/`uname
-r`/path/to/nouveau.ko' above needs substituting for the path to your
nouveau.ko driver. Try locating it and rerun modinfo on it.
Alternatively, you could try compiling nouveau into the kernel by
setting CONFIG_DRM_NOUVEAU=y, reboot and see if that helps.

[IceAmber]

No, the error still there. 

And the script `modinfo /lib/modules/`uname -r`/path/to/nouveau.ko` shows

iceamber@localhost:~ $ modinfo /lib/modules/`uname -r`/path/to/nouveau.ko

modinfo: ERROR: Module /lib/modules/4.12.5-gentoo/path/to/nouveau.ko not found.

[IceAmber]

so, what should I do to locate the driver?

[David Abbott]

try;
modinfo nouveau | grep filename

[Alexander Kapshuk]

du -a /lib/modules/`uname -r`/ | sed '/nouveau.ko$/!d;s/.*\t//'

[IceAmber]

the result is 

iceamber@localhost:~ $ modinfo nouveau | grep filename

filename:       /lib/modules/4.12.5-gentoo/kernel/drivers/gpu/drm/nouveau/nouveau.ko

[IceAmber]

`du -a /lib/modules/`uname -r`/ | sed '/nouveau.ko$/!d;s/.*\t//'` as the same result

[Alexander Kapshuk]

Now run:
modinfo /lib/modules/4.12.5-gentoo/kernel/drivers/gpu/drm/nouveau/nouveau.ko

[IceAmber]

here is the result

[Alexander Kapshuk]

To make 100 per cent certain your driver is loaded, can you also run:

lsmod | grep nouveau

[IceAmber]

here is the result 

iceamber@localhost:~ $ lsmod | grep nouveau

nouveau              1507328  2

i2c_algo_bit           16384  1 nouveau

drm_kms_helper        118784  1 nouveau

Your nouveau kernel driver seems to be OK. That's good news.
The bad news is we're back to square one.

It was glxinfo, which is a part of x11-apps/mesa-progs, that generated
the original error message.
So, perhaps, it is a mesa problem.

Can you please try this command line and see what it outputs:
LIBGL_DEBUG=verbose glxgears

[Alexander Kapshuk]

This reference may help better debug your problem:
https://nouveau.freedesktop.org/wiki/MesaDrivers/

[IceAmber]

here is the outputs

iceamber@localhost:~ $ LIBGL_DEBUG=verbose glxgears

Are you in the 'video' group?

The Mesa drivers wiki page above says:

nv50 and nvc0

Make sure you are using at least Mesa 7.11, but please consider using
latest stable release. You have to use at least the 2.6.38 kernel or
you will encounter memory corruptions. For nvc0 hardware it's
recommended to use at least kernel 3.1.

Bug reports for nv50 and nvc0 can be submitted by following the
general reporting guidelines. Please, also follow the About bugs and
problems section above.

What version is your media-libs/mesa?

Is this the first time you've run into this trouble using the nouveau driver?
What driver did you use before with this piece of hardware proprietary
nvidia one, or nouveau?

[IceAmber]

yes, I have in the video group.

the version of mesa is 

   media-libs/mesa

      Latest version available: 17.0.6

      Latest version installed: 17.0.6

      Size of files: 9,273 KiB

      Homepage:      https://www.mesa3d.org/ https://mesa.freedesktop.org/

      Description:   OpenGL-like graphic library for Linux

      License:       MIT

this is the first time to use the nouveau driver, I used the AMD video card, the model was HD6580, and the driver was radeon before.

[Alexander Kapshuk]

I don't have any further suggestions to make at the moment. Sorry.
Hopefully, someone else might be able to help.

[IceAmber]

thank you all the same. I'll try to fix it if possible

FWIW, modinfo has various options that make using grep like that unnecessary:

% modinfo -h
Usage:
modinfo [options] filename [args]
Options:
-a, --author Print only 'author'
-d, --description Print only 'description'
-l, --license Print only 'license'
-p, --parameters Print only 'parm'
-n, --filename Print only 'filename'
-0, --null Use \0 instead of \n
-F, --field=FIELD Print only provided FIELD
-k, --set-version=VERSION Use VERSION instead of `uname -r`
-b, --basedir=DIR Use DIR as filesystem root for /lib/
modules
-V, --version Show version
-h, --help Show this help
