<h2 id="veille-écran">Veille écran</h2>
<p>Lenvironnement de bureau XFCE, aussi bon soit-il, reste fondamentalement construit sur une technologie plus ancienne que des environnements comme Gnome Shell ou KDE Plasma 5. Ce fait est particulièrement visible dans son choix dutiliser des économiseurs décran, plutôt quun écran de verrouillage moderne. Cependant, bien que lutilisation dun économiseur décran puisse être considérée comme dépassée, XFCE4 le fait bien en offrant aux utilisateurs Xscreensaver, un outil déconomiseur décran facilement configurable et personnalisable.</p>
<h3 id="modifier-logiciel-veille-écran">Modifier logiciel veille écran</h3>
<p>Désinstaller la version existante</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>yay -R xfce4-screensaver
</code></pre></div></div>
<p>Installer xscreensaver</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>yay -S xscreensaver
</code></pre></div></div>
<p>Pour modifier les options de léconomiseur décran sur le bureau XFCE, vous devez accéder à la fenêtre principale des paramètres. Pour y accéder, ouvrez le menu des applications et cliquez sur licône des paramètres. Vous pouvez également appuyer sur les touches <code class="language-plaintext highlighter-rouge">Alt + F2</code> du clavier pour faire apparaître le menu de lancement rapide. Ensuite, écrivez “xfce4-settings-manager” et appuyez sur Entrée pour ouvrir instantanément les paramètres.<br />
<img src="/images/screensaver01a.png" alt="" /></p>
<p>Lorsque la fenêtre principale des paramètres est ouverte sur le bureau XFCE, faites défiler la liste des options à lécran jusquà ce que vous trouviez “XScreensaver Settings” (économiseur décran). Double-cliquez sur licône pour accéder à la zone de configuration de XFCE et de Xscreensaver.</p>
<p>Dans les paramètres de léconomiseur décran pour XFCE, vous verrez un grand nombre doptions différentes à choisir. Ignorez toutes les options et regardez la liste de droite. Dans cette liste, vous avez le choix entre plusieurs économiseurs décran. Nhésitez pas à décocher les cases des économiseurs décran dont vous ne voulez pas.</p>
<p>Pour configurer Xscreensaver de manière à nutiliser quun seul économiseur décran, trouvez le menu “Mode” et cliquez sur la flèche déroulante. À partir de là, parcourez le menu et passez de “Random Screen Saver” à “Only One Screensaver” .<br />
<img src="/images/screensaver02.png" alt="" /><br />
Une fois que le système Xscreensaver est réglé sur “Un seul écran de veille”, parcourez la liste des différents écrans de veille sur la gauche et sélectionnez lécran de veille que vous souhaitez utiliser sur XFCE avec le système Xscreensaver.</p>
<h3 id="modifier-les-déclencheurs-décran-de-veille">Modifier les déclencheurs décran de veille</h3>
<p>Par défaut, léconomiseur décran de XFCE est configuré pour sactiver après environ 10 minutes dinactivité. Pour beaucoup dutilisateurs, 10 minutes est un délai trop court, car ils sont souvent assis devant leur ordinateur, lisant quelque chose avant dêtre interrompus par un économiseur décran.</p>
<p>Si la limite de temps par défaut vous ennuie, vous serez heureux dapprendre quil est possible de modifier le temps dactivation de Xscreensaver. Pour ce faire, ouvrez les paramètres de léconomiseur décran dans XFCE, et rendez-vous dans la zone “Blank After” en bas à gauche de la fenêtre.<br />
<img src="/images/screensaver03.png" alt="" /><br />
Pour définir la durée dactivation de léconomiseur décran, cliquez sur la zone de texte et modifiez-la de 10 minutes à un nombre plus élevé. Fermez ensuite la fenêtre, car les paramètres sappliqueront automatiquement au système.</p>
<h3 id="intervalle-changement-écran-de-veille">Intervalle changement écran de veille</h3>
<p>Si vous utilisez XScreensaver sur XFCE et que vous avez activé “Random Screensaver”, mais que vous naimez pas la vitesse à laquelle le système passe dun écran de veille à lautre, vous pouvez la modifier en allant dans les paramètres “Cycle After” de Xscreensaver.</p>
<p>Pour accéder aux paramètres “Cycle après”, ouvrez les paramètres XFCE sur votre bureau Linux et allez dans les paramètres de Xscreensaver et cherchez “Cycle After” en bas de la fenêtre, sous la zone “Blank After”.<br />
<img src="/images/screensaver04.png" alt="" /><br />
Les paramètres par défaut de léconomiseur décran Xscreensaver pour passer dun économiseur décran à un autre sont denviron 10 minutes. Si vous souhaitez que le système effectue ce changement plus rapidement, modifiez la valeur en dessous de 10 minutes. Ou, pour que le changement soit plus lent, choisissez un chiffre supérieur à 10 minutes.</p>
<p>Une fois le nouveau nombre ajouté au “Cycle After” dans les paramètres de Xscreensaver, le système devrait automatiquement adopter les derniers changements.</p>
<h3 id="désactiver-léconomiseur-décran">Désactiver léconomiseur décran</h3>
<p>Si vous détestez les économiseurs décran et que vous ne voulez pas voir des formes et des vidéos bizarres lorsque votre ordinateur passe en mode veille, vous pouvez désactiver complètement le système Xscreensaver de votre environnement de bureau XFCE. Cest compréhensible ; les économiseurs décran ne conviennent pas à tout le monde.</p>
<p>Il existe deux façons de désactiver le système Xscreensaver sur XFCE. Dans cette section, nous allons vous montrer les deux méthodes.</p>
<h4 id="méthode-1---désactiver-complètement-xscreensaver">Méthode 1 - Désactiver complètement Xscreensaver</h4>
<p>Pour désactiver Xscreensaver afin que le système nentre jamais en vigueur, ouvrez les paramètres de léconomiseur décran dans XFCE. Ensuite, localisez le bouton du menu déroulant “Mode” et cliquez dessus avec la souris pour faire apparaître les options.</p>
<p>Dans le menu des options, trouvez “Disable Screen Saver” et sélectionnez-le pour désactiver définitivement léconomiseur décran de votre environnement de bureau XFCE.<br />
<img src="/images/screensaver05.png" alt="" /></p>
<p>Une fois loption “Disable Screen Saver” sélectionnée, fermez la fenêtre pour terminer lapplication des paramètres.</p>
<h4 id="méthode-2---désactiver-les-animations-mais-conserver-xscreensaver">Méthode 2 - Désactiver les animations mais conserver Xscreensaver</h4>
<p>Vous souhaitez désactiver les animations bizarres que Xscreensaver joue lorsque votre PC est inactif, tout en conservant la fonction de verrouillage ? Voici comment procéder. Tout dabord, ouvrez les paramètres de léconomiseur décran pour XFCE et cliquez sur le menu déroulant “Mode” à laide de la souris.</p>
<p>Recherchez dans le menu déroulant “Mode” loption “Blank Screen Only” et réglez Xscreensaver sur cette option, de sorte que le système verrouille votre écran mais ne joue pas danimations.<br />
<img src="/images/screensaver06.png" alt="" /><br />
Une fois que Xscreensaver est réglé sur “Écran vierge uniquement”, fermez la fenêtre.</p>
