Thanks to you and to everyone who contributed snippets!
For sure, I’ll have to go through this thread again and to set up everything

If this is taking precious time from you, though, I'd recommend booting 
the previous generation of the system to see if it works correctly and 
use that  instead. You can select a previous generation from the GRUB 
menu when booting the system.


Hope that helps, good luck.

Re: Gnome "oh no something has gone wrong..."

[sebastien]

Hi Christophe,

Actually i have the same problem after update guix pull & guix reconfigure to 
the last gnome version. 


Looking to /var/log/message in real time using tail -f /var/log/messages, i 
found there is an ugly segfault after more or less 1 minute in one of gds 
service 
(/gnu/store/qmjsxby7knqmy4h0rr9ahjm6713f150n-gnome-settings-daemon-47.2/libexec/gsd-usb-protection)
 launched by gnome at startup : gsd-usb-protection .gsd-ubs-protect , 
org.gnome.settingsDaemon.USBProtection.desktop ... This service is not 
accessible from dconf editor of gsettings

I found that it's possible to desactivate this gsd-usbprotector gnome service 
by modifying the corresponding gnome.session file : 


RequiredComponents=org.gnome.Shell;org.gnome.SettingsDaemon.A11ySettings;org.gnome.SettingsDaemon.Color;org.gnome.SettingsDaemon.Datetime;org.gnome.SettingsDaemon.Housekeeping;org.gnome.SettingsDaemon.Keyboard;org.gnome.SettingsDaemon.MediaKeys;org.gnome.SettingsDaemon.Power;org.gnome.SettingsDaemon.PrintNotifications;org.gnome.SettingsDaemon.Rfkill;org.gnome.SettingsDaemon.ScreensaverProxy;org.gnome.SettingsDaemon.Sharing;org.gnome.SettingsDaemon.Smartcard;org.gnome.SettingsDaemon.Sound;org.gnome.SettingsDaemon.UsbProtection;org.gnome.SettingsDaemon.Wacom;org.gnome.SettingsDaemon.XSettings;


BUT ... this is a readonly file in /gnu/store, so i'm actually blocked. I don't 
know how to modify this file to remove org.gnome.SettingsDaemon.UsbProtection

I guix rollback to go back to the previous working gnome version :(

Best regards,
Src.

You need to run it using -Q.
See 

And even then you may experience crashes...it's very much a work in
progres!

[Cayetano Santos]

Hi Guix,

  An update to guile-emacs[1] just landed on the repos.

https://yhetil.org/guix-patches/87h63umi1m@retrospec.tv/

  I decided to give it a try, out of curiosity after this [2] talk. No
  luck, though, as it crashes for me.

guix install guile-emacs
emacs -q

  Anyone else tried ?

Thanks,

 I'd migrate your system to the Btrfs file system, which dynamically
 allocates inodes and never runs out of them.  It has a few peculiarities
 that must be taken into account, such as the requirement to run 'btrfs
 balance' periodically to reclaim unallocated blocks, but otherwise it's
 stable and has interesting features.  Make sure to use it with Zstd
 compression to magically double (about) your storage capacity :-).

Excellent!  Just don't forget to run the 'btrfs balance /' command
regularly, otherwise over time the allocated storage chunks of Btrfs
gets all used up, despite what 'df' and other tools might say, and this
is an annoying situation to recover from.

Here are some btrfs-related jobs I use:

--8<---cut here---start->8---
(define btrfs-balance-job
  ;; Re-allocate chunks which are using less than 5% of their chunk
  ;; space, to regain Btrfs 'unallocated' space.  The usage is kept
  ;; low (5%) to minimize wear on the SSD.  Runs at 12 PM every 3 days.
  #~(job '(next-hour-from (next-day (range 1 31 3)) '(12))
 (lambda ()
   (system* #$(file-append btrfs-progs "/bin/btrfs")
"balance" "start" "-dusage=5" "/"))
 "btrfs-balance"))

(define btrfs-scrub-job
  ;; Scans the whole disk data to detect and repair errors.  Runs at 12
  ;; AM monthly.
  #~(job '(next-hour-from (next-month) '(12))
 (lambda ()
   (system* #$(file-append btrfs-progs "/bin/btrfs")
"scrub" "start" "-c3" "/"))
 "btrfs-scrub"))

(define btrbk-job
  #~(job '(next-hour)
 (lambda ()
   (system* #$(file-append btrbk "/bin/btrbk")
"-q" "-c" #$(local-file "btrbk.conf") "run"))
 "btrbk"))
--8<---cut here---end--->8---

I'd also advise using just compress=zstd and not compress-force=zstd, as
the later limits the size of Btrfs extents (if I recall the terminology
right) created to 512 KiB or similar, leading to a huge number of
extents over time, which can slow some things down such as mounting the
file system at boot.

In case you have any question, knowledgeable Btrfs folks are usually
responsive in #btrfs on Libera.chat.

Cheers!

Re: Evolution fails to connect to CalDAV via TLS outside Gnome's environment

I tried this time with plasma-desktop-service-type, evolution was
asking for passwords repeatedly, I added gnome-keyring-service-type, it
was the same, then I added gnome-keyring and this was fixed.

The errors with CalDAV and CardDAV were different but they were fixed
by addting gsettings-desktop-schemas, thanks for hint!

Before this, I also added dconf because without it, I was not able to
change any setting in evolution.

It would be beneficial for Guix users if such information could be
captured somewhere.

cannot build a kernel with my custom config

[Adam]

Hello Guix!
Recently I've read about customizing the kernel on this page
https://guix.gnu.org/cookbook/en/html_node/Customizing-the-Kernel.html
After reading I decided to try one of described there ways of
providing my own kernel configuration.
Long story short, in my configuration I disabled everything related to
rtw89 driver
```
...
CONFIG_RTW89=n
CONFIG_RTW89_CORE=n
CONFIG_RTW89_PCI=n
CONFIG_RTW89_8851B=n
CONFIG_RTW89_8852A=n
CONFIG_RTW89_8852B=n
CONFIG_RTW89_8852C=n
CONFIG_RTW89_8851BE=n
CONFIG_RTW89_8852AE=n
CONFIG_RTW89_8852BE=n
CONFIG_RTW89_8852CE=n
...
```
And I used this code snippet to define my custom kernel package
```
(define-public my-linux-package
  (package
(inherit linux-libre)
(native-inputs
 `(("kconfig" ,(local-file "config"))
  ,@(alist-delete "kconfig"
  (package-native-inputs linux-libre))
```
After building my package I checked the config file which is stored in
the derivation. Unfortunately, that file had these options
```
CONFIG_RTW89=m
CONFIG_RTW89_CORE=m
CONFIG_RTW89_PCI=m
CONFIG_RTW89_8851B=m
CONFIG_RTW89_8852A=m
CONFIG_RTW89_8852B_COMMON=m
CONFIG_RTW89_8852B=m
CONFIG_RTW89_8852BT=m
CONFIG_RTW89_8852C=m
```
I assume that guix used default kernel configuration instead. So my
question is - is there any way to provide my own .config file to build
a kernel package?
