This we already figured out previously in this thread :) 
And:

"Label : GNU with Linux-Libre 4.15.7 (beta)
Prev. generation  : 0  
Current   : Yes
Number of packages: 88  Packages
File name: 
  /var/guix/profiles/system-4-link"

The question remains.

Your user’s profiles are not the only ones that can keep packages alive.
You also have a system profile with potentially multiple generations.
They are stored under /var/guix/profiles/system*

As the manual says, this is for deduplicating files in the store.

Seems I has understood not until the end of..
After running 'guix package -d && guix gc':

Re: Wayland setup

[Thorsten Wilms]

Hi!

Thank you, Andreas and Oleg.


Aside of additional services, this seems to be the way to get Weston 
with a minimum of stuff installed:


---

(use-modules (gnu)
 (gnu packages freedesktop) ; for wayland
 (gnu packages xorg)) ; for xorg-server-xwayland
(use-service-modules networking)

(operating-system
  ...

  ;; Trying weston-launch as plain user: got told to either run it from
  ;; an active and local (systemd) session, or add the user to  weston-
  ;; launch. weston-launch needs to be created, first:
  (groups (cons (user-group (system? #t) (name "weston-launch"))
%base-groups))

  (users (cons (user-account
(name "thorwil")
(group "users")
(supplementary-groups '("audio"
"netdev"
"video"
"weston-launch"
"wheel"))
(home-directory "/home/thorwil"))
   %base-user-accounts))

  ;; Globally-installed packages.
  (packages (cons* xorg-server-xwayland wayland weston %base-packages))

  ;; Add service to the baseline
  (services (cons* (console-keymap-service "de-latin1-nodeadkeys")
   (dhcp-client-service)
   (simple-service 'etc-additions
   etc-service-type
   (list `("inputrc" ,(plain-file 
"inputrc" "set bell-style none"

   (gpm-service) ; mouse on the console
   %base-services)))

---

From my reading, the command to launch Weston outside of an X session 
is weston-launch. The first attempt led to a message about the 
"weston-launch" group. It would have been nice to have that taken care 
of automatically, though I don't see how that could happen in harmony 
with hand-edited configuration.


The next error: XDG_RUNTIME_DIR not set. 
https://wayland.freedesktop.org/building.html offers this script, which 
I used:


if test -z "${XDG_RUNTIME_DIR}"; then
export XDG_RUNTIME_DIR=/tmp/${UID}-runtime-dir
if ! test -d "${XDG_RUNTIME_DIR}"; then
mkdir "${XDG_RUNTIME_DIR}"
chmod 0700 "${XDG_RUNTIME_DIR}"
fi
fi

So now "weston-launch" will lead to no (obvious) effect, except printing 
this one mangled line:
"t it.org/wiki/Specifications/basedir-specis not 
set.n2-weston-3.0.0/bin/weston 2t=weston=3.0.0"


Specifying a TTY like "weston-launch -t 2" makes no difference, except 
for "7", in which case the whole system becomes unresponsive after an 
Alt-F7.


I tried with and without this ~/.config/weston.ini:
---
[core]
xwayland=true

[keyboard]
keymap_layout=de-latin1-nodeadkeys

[output]
name=WL1
mode=2560x1600
---

Any ideas? Success stories with any other Wayland compositor outside of 
Gnome?

VLC could not decode the format "ssa " (SubStation Alpha subtitles)

[Dang Duong]

I have installed the latest version of VLC (2.2.8) on Trisquel 7.0 using
Guix. It works normally with .srt files but cannot open .ass files. I tried
installing libass but it still doesn't work.
