** final bug report

From: Joshua Branson <jbranso@dismail.de>
To: bug-guix@gnu.org
Subject: Something appears to disable linux kernel modules from loading.
--text follows this line--

Hello!

tl;dr

Something is causing linux 5.4.20 not to load kernel modules at boot.
Perhaps the culprit is the shepherd 0.7.0.

So I recently reconfigured guix on my ThinkPad T400.

#+BEGIN_SRC sh
$ guix describe

#+END_SRC

After I rebooted sway refused to start.  The sway error message said
#+BEGIN_SRC sh
$ sway

[backend/backend.c:339] Failed to open any DRM device.
[sway/server.c] Unable to create backend.
#+END_SRC

So sway is not starting.  I believe this is because my i915 intel
driver is not loaded.  I know this is the case, because the text on my
virtual console is LARGE.  $ sudo modprobe i915 loads the required
driver. And I can now log into sway.

However, my ethernet driver is not loaded.

#+BEGIN_SRC sh
$ lsmod | grep e1000e

#+END_SRC

#+BEGIN_SRC sh
$ sudo modprobe e1000e
#+END_SRC

Then I ran ifconfig, and indeed I now have an ethernet device.

#+BEGIN_SRC sh :results output :exports both
$ ifconfig

#+END_SRC

And I now have an internet connection.

But I do not have a working touchpad.  I guess my touchpad driver is
not loaded.  I'm not certain what driver my touchpad uses, so for now
I am doing with out.

I then went and asked for some tips on irc.  HappyEnt claimed the
problem for him was commit 205c1e0.

janneke was also having issues with kernel modules not being
automatically booted.  He said that this commit worked for him:
ef2b1d2c8b60776bf66573b0c810474e9e1a4abd. He then said that commit
d39885a8a9e0e03c2bf6277d475d384168bba642 also worked, which implied
the problem was not the linux version 5.4.20, but possibly the
shepherd.

I tried reconfiguring with commit
d39885a8a9e0e03c2bf6277d475d384168bba642, to see if that solved my issue.

#+BEGIN_SRC sh :results output :exports both
 guix time-machine --commit=d39885a8a9e0e03c2bf6277d475d384168bba642 -- system reconfigure
#+END_SRC

#+BEGIN_SRC sh
$ uname -r
5.4.20-gnu
#+END_SRC

janneke's commit did solve my issue.  After rebooting, sway starts, I
have internet, and my touchpad and sound work.

Man I love guix system.  It really does work smoothly, even when you
have problems.  So thanks for making a great GNU/Linux distro!


Thanks Joshua

I started using sway, and my mouse issue went away.

Ricardo suggests blacklisting the usbkdb module.

modeprobe.blacklist=usbkdb

(kernel-arguments '("modprobe.blacklist=usbkbd"))

I need to run
#+BEGIN_SRC sh :results output
$ guix pull
# guix pull
#+END_SRC

;; Edit configuration.scm to add ‘kernel-arguments’ to the config:
;; (operating-system
;;    …
;;    (kernel-arguments '("modprobe.blacklist=usbkbd")))

How do you list all of your input devices?

#+BEGIN_SRC sh :results output :exports both
xinput
#+END_SRC

And it looks like #3 is my keyboard.

Here's a question for ya.  How do you know what driver is powering each input device?

#+BEGIN_SRC sh :results output :exports both :dir /var/log
cat Xorg.0.log | grep "Using input driver"
#+END_SRC
