Fluxbox sur OpenBSD

L'histoire

Ma chérie utilisait debian depuis longtemps. Mais depuis la mise à jour vers buster, c'était très lent. J'ai décidé d'installer OpenBSD à la place, et ça semble mieux lui convenir.

Configuration

Installation

OpenBSD est facile à installer. J'ai choisi de chiffrer tout le système (et vous devriez probablement en faire autant…)

Xenodm

Le gestionnaire de connexion est xenodm. J'ai activé l'autologin puisqu'elle est seule à s'en servir :

# rcctl enable xenodm
# echo 'DisplayManager._0.autoLogin: user' >> /etc/X11/xenodm/xenodm-config

Configuration de Fluxbox

Style

Le style s'appelle ion. Il va bien avec le thème gtk Adwaita.

Toolbar

Le menu peut s'ouvrir en cliquant en bas à gauche de la barre d'outils. Dans ~/.fluxbox/init :

session.screen0.toolbar.tools:  RootMenu, iconbar, systemtray, ,prevworkspace, workspacename, nextworkspace, clock
session.screen0.workspaceNames: # 1,# 2,# 3,# 4
session.screen0.strftimeFormat: %d/%m - %H:%M

Le volume du son

Scroller sur la barre ou le bureau change le niveau sonore. Dans ~/.fluxbox/keys

XF86AudioRaiseVolume :Exec mixerctl outputs.master=+10
XF86AudioLowerVolume :Exec muxerctl outputs.master=-10
XF86AudioMute :Exec mixerctl outputs.master.mute=toggle
# volume on bar and desktop
XF86AudioRaiseVolume :Exec mixerctl outputs.master=+10
XF86AudioRaiseVolume :Exec mixerctl outputs.master=+10
XF86AudioLowerVolume :Exec muxerctl outputs.master=-10
XF86AudioMute :Exec mixerctl outputs.master.mute=toggle

Le menu

Le menu ne contient que ce qui est utile, pas besoin de chercher.

Quelques précisions :

La capture d'écran permet de sélectionner une partie de l'écran, et copie la capture dans le presse papier pour coller rapidement dans LibreOffice ensuite. Il faut juste Graphicsmagick et xclip. scrotncopy.

L'entrée “volume” appelle setvol :

#!/bin/sh
# set volume to percent
vol=$(( $1 * 255 / 100 ))
mixerctl outputs.master=${vol}
exit

Pour redémarrer/éteindre le système : /etc/doas.conf :

echo "permit persist :wheel " >> /etc/doas.conf
echo "permit nopass :wheel cmd /sbin/shutdown" >> /etc/doas.conf
echo "permit nopass :wheel cmd /sbin/reboot" >> /etc/doas.conf
echo "permit nopass :wheel cmd /usr/sbin/apm" >> /etc/doas.conf
