PostPosted: Tue Jan 12, 2021 10:44 pm    Post subject: why is xorg built with nouveau when I have AMDGPU? [solved] Reply with quote

This seemed like the best forum for the question:

I've just gotten xorg running, and am seeing a slot conflict when an installation pulls in libdrm:
Code:
 >=x11-libs/libdrm-2.4.89[video_cards_radeon] required by (x11-drivers/xf86-video-ati-19.1.0:0/0::gentoo, installed) USE="udev" ABI_X86="(64)"
                             ^^^^^^^^^^^^^^^^^^                                                                                                                                                                           
    >=x11-libs/libdrm-2.4.60[video_cards_nouveau] required by (x11-drivers/xf86-video-nouveau-1.0.16:0/0::gentoo, installed) USE="" ABI_X86="(64)"


I find that xorg doesn't have an xorg.conf anymore. I pretty much ran down the handbook during installation, and xorg setup. I've got an AMD GPU card and the amdgpu module is loaded. I built the kernel with all the vanilla defaults:
Code:
localhost ~ # cat /usr/src/linux/.config|grep -i nouveau
# CONFIG_DRM_NOUVEAU is not set


And I haven't monkeyed with USE flags or anything... so it seems like nouveau is coming along for the ride, but I don't see how it got onboard in the first place.

How do I get rid of it - any pointers?

whitt,

What do you have is VIDEO_CARDS= in make.conf.

Depending on your AMD card model, different settings are required.
Please post the output of
Code:
lspci -nnk

Did you read this: https://wiki.gentoo.org/wiki/AMDGPU or this: https://wiki.gentoo.org/wiki/Radeon ?

In an other thread I wrote: "An exact description of your problem is half the way to solve it." Let me complement: ... and it saves (your) time, because nobody must ask you which graphics card you are using.

I did read both wikis, and am not sure what i should have taken away from them... My card is a 5600, in the navi family of chips.

At some point, xorg decided it needed the nouveau module, and it seems to be causing problems. If my understanding is incorrect, I don't see anything at either wiki explaining it to me differently...

What am I missing here?

Probably you used improper command to install nouveau and now it is in your world set. Never ever emerge dependencies without --oneshot (-1). Solution - remove it from your word file and run --depclean, it will remove all packages from your system which are not referenced in world set nor are dependencies. Alternate - simply unmerge it. Running --depclean is still recommended afterwards.

whitt,

VIDEO_CARDS="amdgpu" isn't quite enough. You need radeonsi in there too.

VIDEO_CARDS= has got to be a bit of a mess over the years different packages use it for different things.
amdgpu gets you the Xorg driver. and radeonsi gets you mesa built with the acceleration you want.

What does
Code:
emerge -pv x11-base/xorg-drivers
tell ?

Your original snippet
Code:
 >=x11-libs/libdrm-2.4.89[video_cards_radeon] required by (x11-drivers/xf86-video-ati-19.1.0:0/0::gentoo, installed) USE="udev" ABI_X86="(64)"
                             ^^^^^^^^^^^^^^^^^^                                                                                                                                                                           
    >=x11-libs/libdrm-2.4.60[video_cards_nouveau] required by (x11-drivers/xf86-video-nouveau-1.0.16:0/0::gentoo, installed) USE="" ABI_X86="(64)"


You have x11-drivers/xf86-video-ati and x11-drivers/xf86-video-nouveau installed.
That suggests that you have some per package settings adding in VIDEO_CARDS="nouveau readeon", or the USE expanded equivalent.

ah crap. OK - added radeonsi to VIDEO_CARDS.

output of emerge -pv blah blah blah:
Code:
localhost ~ # emerge -pv xorg-drivers

These are the packages that would be merged, in order:

1. I think Buffoon is right. Please post the output of your /var/lib/portage/world. I think we have to delete here something.
2. Also what Neddy said: You need VIDEO_CARDS="amdgpu radeonsi" but wait before trying emerge again because of (1).

i was writing back to others when your post popped up... only saw this by accident while searching other things. i didn't even know what nouveau was until i ran into a problem with libdrm, not sure how i would have accidentally emerged it.

i did run emerge -pvC on the driver, and it told me it was needed by xorg. i'm not certain i want to force it out, without understanding why xorg thinks it needs it.

In the mean time I want to explain "Never ever emerge dependencies without --oneshot (-1)" ... ;-)

If you emerge package A this will be recorded in this world file.

If package A needs package X you will find X NOT in this file, because portage knows itself A need X.
If A gets an update and needs now Y INSTEAD for X, portage will catch Y and at some time you have to do an "emerge -c" deleting all unused packages like X.

IF YOU do an update for X without parm "-1" then this package will go also into world, even it is only a dependent package.
If A gets now an update and needs now Y INSTEAD for X, portage will try to catch Y and there exists two possibilities:

a) X is no problem for Y and ca coexist. This is a minor problem ... but you will never get it deleted with "emerge -c" - you must delete it by yourself with "emerge -C X"
b) X and Y cannot installed both. This is a major problem and must be resolved by yourself with deleting X ->

The clean way: "emerge -C X"
or dirty: Deleting this entry from your world-file ...

whitt,

What does
Code:
grep -R -i radeon /etc/portage/
grep -R -i nouveau /etc/portage/

Have to say?

Maybe a bad attack of auto-unmask?

Okay. Do you really want xorg-x11 (it is huge) or only xorg-server (only needed by a WM) ?

Delete xorg-drivers in your world-file and do an "emerge -vD xorg-server" again (and dont emerge the drivers again).

Pietinger - great question, I'd originally emerged only xorg-server, but ran into problems getting it configured / started, then poked around and ended up with drivers and x11 installed... if not needed, I'll definitely remove xorg-drivers. and FWIW, every package installed has been explicit, I have not installed any dependencies, only the parent packages i wanted.

NeddySeagoon - the number of hits for radeon is huge, but I think the interesting thing is that there are zero ocurrences of nouveau in /etc/portage...
Code:
localhost ~ # grep -Ri nouveau /etc/portage/                                                 
localhost ~ #


FWIW, after adding radeonsi to VIDEO_CARDS, I just started 'emerge -auv --newuse'ing every package i could think of related to xorg, reemerged xorg-drivers, and now nouveau is gone.

I feel kinda bad, because I have no idea what caused the problem, or how it was fixed. And since you're helping me out, I figured you'd like to know what caused it and what fixed it... Unfortunately I just started shotgunning it and now it's seemingly OK - no more slot conflict for libdrm.

I'm sorry if I spoiled the crime scene, but I'm grateful for your help none the less! : )

whitt,

xorg-server is the bit than draws windows on your local system.
It depends on xorg-drivers, so it need not be emerged explicitly and if it is, it should not be in world.
xorg-drivers is configured by VIDEO_CARDS=

A long time ago, if VIDEO_CARDS= was not set, xorg-drivers didn't install any video drivers at all.
That was easy to diagnose and fix, so I quite liked that.
In the interests of being beginner friendly, that god changed to install some subset of the video card drivers.
If you managed to install xorg-drivers with VIDEO_CARDS= not set, you would have got that 'some subset'

Pietinger - great question, I'd originally emerged only xorg-server, but ran into problems getting it configured / started, then poked around and ended up with drivers and x11 installed... if not needed, I'll definitely remove xorg-drivers. and FWIW, every package installed has been explicit, I have not installed any dependencies, only the parent packages i wanted.

Quick answer: xorg-drivers is not a "parent" package. You even would NOT need xorg-server itself as "parent" package IF you would install kde, gnome or xfce or ... They all pull in xorg-server by themself ... so its funny, but after you installed e.g. kde you could delete ALL your xorg-... entries from world (I have kde and none xorg entry in my world file anymore. But I also did the installation of X11 first to see if there is no problem, and afterwards I did my kde installation).

P.S.: If you do now an "emerge -cp" you should see some packages you dont need anymore.

OK - so maybe I jacked things up trying to monkey around with xorg. I'll take xorg-drivers out of world.

What I did was similar to what you describe - I installed "X" only to see I could get a black screen and xeyes running. That was the oldschool method I recalled to make sure my drivers were set up correctly, and what i was worried about verifying. Afterward, I installed flux and e.

I'm still not sure how vouveau ended up in here, but I'm glad to see it gone : )

Pietinger - done, solved. I'll do likewise where you helped me with my bootloader problem.

THanks!

pietinger,

If Desktops and Window Managers pull is xorg-server, that's new.

Xorg is network transparent. Its OK to install Desktops and Window Managers without xorg-server if you intend to run them remotely and not display the video on those hosts.
xorg-server is only required to render the image, so it only needs to be on the system you sit in front of. That's the most common use case today in that its all on one system.
Even then, Xorg still talks to itself over the network.

Neddy,

I dont know since which time this is true, but I really dont have any xorg-entry in my world-file. I think it is because with the 17.1/desktop-profile you have USE="X" and if you emerge plasma-meta it automatically pulls in xorg-server.

It is KDE/Plasma specific, I executed
Code:
USE='elogind X cups dbus pam qml text vorbis egl wayland opengl' emerge -tpv plasma-meta
in a headless server of mine and it really pulls in xorg-server. I think it is mesa which requires wayland flag which in turn requires xorg-server. Brrr, what a bloat.
