I have this problem to install Guix System:

[Attachment]


After this, the screen turns black and nothing is displayed.


I first downloaded the Guix System, extracted the iso with this command: "unxz" and then burned it to a 4.7GB DVD-R with "Brasero". I did not sign the downloaded file from the beginning

This sounds similar to <http://issues.guix.gnu.org/44257>.  Do you 
have an ATI video card?  They are known for problematic hardware.

Please try the two work-arounds suggested there: adding ‘radeon’ 
to the GRUB kernel command line, or burning the ‘latest’ ISO if 
that doesn't help.

Kind regards,

Tobias,
I have tried both of those options, new current image and appending radeon on the kernel load line, but to no avail.
It never reaches login on tty1, but I can switch to tty2 and update guix and run commands.
The graphics card I have is an AMD/ATI Radeon HD 7800
Can the nouveau driver be installed and then tweak the X config file to use and load the nouveau, (if that is the one I need),driver?

Thanks, yes it is related, I was able to install the system by putting "nomodeset" in grub.

Which is probably related to GDM or graphics, I was able to log in with the root user. I then updated the system with the "guix pull" and "guix system reconfigure /etc/config.scm" commands. To apply the updates, I rebooted the system and then I now have this problem:

Guix has some incompatibilities like (issues.guix.gnu.org/43985) with my computer.
What are these? what's the solution?

Your issues are post-install, I think, so the installer worked
properly, so Guix basically works.  However:

Possibly you will not get a good experience because (if I understand
it correctly) Linux-libre might have various incompatibilities because
it is deliberately lacking non-free firmware.

You might work around the graphics issues by using nomodeset or
blacklisting nouveau and then using uvesafb like
<https://lists.gnu.org/archive/html/bug-guix/2020-04/msg00320.html>.
I’m not sure if all that is really necessary.

Your 7.jpg shows this message:

[  18.727379] usb 1-1.3: Fatal – failed to load firmware

This may be because Linux-libre

I do not know if you deliberately did not reply to all.  I hope you do
not mind me quoting you.

Guix will not provide support for that, but there is a Guix channel
where others are doing that.  (I cannot link to it and of course it is
a trade-off because parts of Linux (instead of Linux-libre) are
nonfree.)  The uvesafb solution I linked to in my last mail is an
alternative that I use for one old laptop of mine that does not make
much use of your GPU and is therefore slower and may or may not be
more power-hungry, I don’t know.

soheilkhanalipur reported problems with an Nvidia GPU.  I had not seen
that before, maybe the above also helps.  I do not know if
soheilkhanalipur’s USB issues are still problematic.

(Sorry I accidently sent out a draft e-mail before, but it was mostly
complete.)

Regards,
Florian

Does this mean I have non-free firmware?
I put "modprobe.blacklist=i915" in grub, but the problem is not resolved.
I am confused! Is there no solution?

Do you have another Linux Live Distro at hand to check what the device at
USB 1-1.3 actually is? This might help.

The problem was solved!
This time, during the installation process, I put the language, keyboard and all the names in English, and I was able to log in with my user (not the root) and update it. I hope this problem is solved soon. Yes, as I thought, this is related to issues.guix.gnu.org/43985 <http://issues.guix.gnu.org/43985>
