It is, but:

  1. It=E2=80=99s not as prominent and explicit as it could be: it=E2=80=99=
s within a
     paragraph (as opposed to a table), there=E2=80=99s no mention of iwlwi=
fi,
     etc.

  2. The situation got worse in the meantime: see =E2=80=9CBackground=E2=80=

     <https://blog.einval.com/2022/04/19>.

By devices, I meant primarily WiFi devices, sound cards, etc. for the
more common x86_64 hardware.

Thanks,
Ludo=E2=80=99.

gnu/system.scm contains

(define %default-modprobe-blacklist
  ;; List of kernel modules to blacklist by default.
  '("usbmouse" ;races with bcm5974, see <https://bugs.gnu.org/35574>
    "usbkbd")) ;races with usbhid, see <https://issues.guix.gnu.org/35574#1=
8>

Perhaps send a patch or open a bug to add your wifi=E2=80=99s module to the
default modprobe blacklist.

Regards,
Florian

Are you sure this is not a graphics lockup?  If it were a graphics
lockup, you could press E in the GRUB menu and add nomodeset to the
linux boot line.

My impression is that the dire wifi situation is explained well enough
in Hardware Considerations already.

On other common problems, even if I no longer agree with all I wrote at
<https://issues.guix.gnu.org/36786>, I remember that others claimed
somewhere that not all AMD GPUs are bad, and h-node says some Intel
integrated graphics are indeed not working, so it is not easy to
generalize when it comes to GPUs.

There is a list of image types like novena and pine64.  The Pinebook
image is even on the website, which is kind of more prominent than the
manual.  Then there also are bootloaders for some devices in the Guix
source code (not prominent at all).

By the way, it did play a part when my family bought an odroid c2 that
Guix had a bootloader for it, then there came a commit

commit 2bb915e679b8a9e071f15b4caa3274fe9c6396c1
Author: Efraim Flashner <efraim@HIDDEN>

    U-boot for this target requires a binary blob to boot correctly.

Yes, I agree there should somehow be a warning for example if the
uvesafb module gets loaded.  I need to think about that.

Florian

I think automatically generating a list of nonfree modules would work,
as long as we make sure we don't recommend that a user acquire them.

Also, I tried to run linux-libre on my desktop and it booted but
refused to login because it tried to load the nonfree wifi card. Could
it be patched so that nonfree modules are ignored, and I could at least
get a desktop without wifi? Everything else afaik is free hardware.

(if this is a separate issue, I can make a bug report)

Hi!

This discussion and others we had at the Ten Years of Guix event makes
me think we should strive to avoid bad surprises by being more
explicit.  Concretely, we could:

  =E2=80=A2 Under =E2=80=9CHardware Considerations=E2=80=9D, list common de=
vices known not to
    work without non-free {firm,soft}ware, such as Intel Wifi (iwlwifi).
    We cannot be exhaustive but we should at least mention common
    problems with recent x86_64 laptops.

  =E2=80=A2 Under =E2=80=9CHardware Considerations=E2=80=9D, make the list =
of devices known to
    work clearer, in tabular form, perhaps expanding it.

  =E2=80=A2 In the installer, print a message upfront when unusable devices=
 are
    found=E2=80=94typically Intel wifi.

    I=E2=80=99m not sure how to do this though.  Maintaining a list of know=
n-bad
    devices doesn=E2=80=99t sound great, but it=E2=80=99s better than nothi=
ng.
    Instrumenting the firmware-loading mechanism would be a good way to
    detect problems, but I think it=E2=80=99s not even getting invoked in
    Linux-libre (or not always).  Alternatively, we could tweak
    deblobbing so that it produces a list of known-bad modules or
    devices.

Thoughts?

Ludo=E2=80=99.

Your patch addresses many things at once; mostly I wanted to refer you
to the AMD GPU bug.  My experience was being quite disgruntled when I
learned AMD had only =E2=80=9Cfree=E2=80=9D drivers marketing-wise but not =
truly free
drivers because no free firmware.

My opposition to recommending Thinkpads is mostly opposition to
recommending specific hardware, which should be the job of RYF and
h-node.  Guix cannot keep track.

Your Parabola link is really interesting though; it makes it sound like
even RYF hardware is not without wi-fi trouble=C2=A0=E2=80=A6

When you write

> It would be nice to=20
> at least recommend some specific hardware.  :)  I think the current
> manual is too vague for newcomers.  Just my 2 cents.

then I do agree, but I also think it cannot be in scope for Guix.

H-node says some Intel UHD have no 3d acceleration.

I can re-word to to say "old integrated Intel GPUs".  I'm not sure how
old I should say though.  5 years?  Will the Intel Arc graphics cards
be FYF or do they have a binary blob.  I don't actually know...

Hmm Joshua, recommending these thinkpads may be good or may be bad.

Off-the-shelf hardware too often is at odds with freedom, and newcomers
underestimate how hard it is to find hardware.

IMHO ARM and Power need not be mentioned so explicitly.  On the website,
there is no Guix System download link for ARM except the Pinebook image
(I don=E2=80=99t own a Pinebook and can=E2=80=99t test that).  Guix on ARM =
works well,
now that rsvg works on ARM.

And once there is a new release, bordeaux will be enabled by default,
then Guix on ARM will be much better even by default.

Hmm Joshua, recommending these thinkpads may be good or may be bad.

Off-the-shelf hardware too often is at odds with freedom, and newcomers
underestimate how hard it is to find hardware.

For graphics cards <https://issues.guix.gnu.org/36786> =E2=80=9CWarn of AMD=
 GPUs
unusable with Guix System=E2=80=9D is related.  As Ricardo said there, we do
point to h-node.

It would be bad to make recommendations that end up not working.  I have
doubts if new Intel GPUs is a safe advise.

IMHO ARM and Power need not be mentioned so explicitly.  On the website,
there is no Guix System download link for ARM except the Pinebook image
(I don=E2=80=99t own a Pinebook and can=E2=80=99t test that).  Guix on ARM =
works well,
now that rsvg works on ARM.

And once there is a new release, bordeaux will be enabled by default,
then Guix on ARM will be much better even by default.

Regards,
Florian

It would be nice if the guix manual mentioned that it really works best with 
2GB of RAM. and that the best supported archeteticure is X86_64. 

* doc/guix.texi (Hardware Considerations):  add a reccomended system and a
