====== Get Desktop menus for custom applications: ======
A "desktop" file is necessary for it.
===== Storage of the  desktop file: =====
  * into the folder ''/usr/share/applications'' if the entry should be displayed for every user
  * into the folder ''~/local/share/applications'' if the application is only available for 1 user

===== The desktop file: =====
A desktop file contents following:
<code>[Desktop Entry]
Encoding=UTF-8
Type=Application
Name=name of the application
Name[fr_FR]=name of the application in the foreign language
Comment=comment about the application 
Comment[fr]=comment about the application in the foreign language
Exec=/path/of/the/script/of/the/application
Icon=/path/of/the/icon
Categories=GTK;Utility; </code>

  * to get the "right" category: have a look into existing desktop files of applications of the category that you want to choose
  * ''/usr/share/icons/oxygen/base/32x32/'' is a folder that contains a lot of good icons

====== Activer une touche "compose" perso ======
Sous ''paramètres'' => ''clavier'' => ''saisie'' il est possible d'activer la touche compose.
Malheureusement seules les touches proposées peuvent être sélectionnées à cet effet. Voici comment activer une autre touche:

  * créer dans ''~/scripts'' un script qui "xmodmap"  en se référençant à ''~.xmodmap'' <code>
#!/bin/bash
sleep 15 && xmodmap ~/.xmodmaprc
exit 0;</code> La tempo est nécessaire pour que le xmodmap soit lancé après l'ouverture complète de la session (voir [[https://bugzilla.redhat.com/show_bug.cgi?id=873656#c16|Commentaire #16]])
  * avec la commande ''xev'' et en appuyant sur la touche à assigner pour la repérer: c'est la ''kexcode XX''
  * créer un fichier ''~.xmodmaprc'' qui désigne la touche <code>
keycode 64 = Multi_key</code>
  * créer dans ''/usr/share/application'' l'entrée ''.desktop'' qui pointe sur le script: <code>
[Desktop Entry]
Encoding=UTF-8
Type=Application
Name=activation touche compose
Name[fr]=activation touche compose
Comment=activation touche compose
Comment[fr]=activation touche compose
Exec=/home/mon_user/scripts/activation_touche_compose
Icon=applications-utilities
Categories=GTK;Utility;
Name[fr_FR]=activation_touche_compose</code>

=> Résultats:  \\  
- mon script est visible dans le menu des applications  \\  
- mon script fonctionne quand je le lance depuis le menu des applications  \\  
- dans l'utilitaire ''tweak'' je peux le sélectionner pour un démarrage automatique

Vérifier que l'entrée ''.desktop'' est présente dans ''/home/tonuser/.config/autostart/'', l'ajouter le cas échéant.

====== Disable auto-lock of the screen ======
Even if the auto-lock of the screen is disabled by the parameters of the screen saver, the screen get locked after inactivity. \\ 
To disable this: got to ''parameters''  => ''confidenciuality'' and disable the lock of the screen.

====== Get the full path in Nautilus ======
Target: get the full path of the files (/folder/sub-folder/file) in the bar of nautilus. \\ 
  * only 1 time: Simply press ''Strg'' and ''l'' \\ To return to the original breadcrumb view, make sure that the editable text area has the focus then press the ''Esc'' key. \\ \\ 
  * To make it permanent type: <code>gsettings set org.gnome.nautilus.preferences always-use-location-entry true</code>

====== Extensions Gnome ======

[[https://wiki.gnome.org/Projects/GnomeShellIntegrationForChrome/Installation|Source]] \\ 
  * install the module ''gnome-shell-integration'' into firefox (modules => extensions)
  * install the second part of the module: <code>
# dnf copr enable region51/chrome-gnome-shell
# dnf install chrome-gnome-shell </code>

For extensions about the system monitoring on my "KCN"-PC:
<code># dnf install NetworkManager-glib-devel libgtop2-devel</code>

====== Nextcloud and gnome-keyring ======
To make the client Nextcloud able to store the passwords into the gnome-keyring, make sure that boths rpms ''libgnome-keyring'' and ''gnome-keyring'' are instaled.

====== Get icons on Desktop by Gnome 3.28 ======
Source: https://blog.drsolly.com/2018/05/upgrading-to-fedora-28.html \\ 
I prefer put the desktop file into /usr/shrare/applications/ and give each user the possibility to activate it via gnome-tweak => autostart:
  * <code># dnf install nemo</code>
  * <code># nano /usr/share/applications/activation_nemo_AG.desktop</code>
  * and enter in it: <code> [Desktop Entry]
Type=Application
Name=Nemo
Comment=Start Nemo desktop at log in
Exec=nemo-desktop
OnlyShowIn=GNOME;
AutostartCondition=GSettings org.nemo.desktop show-desktop-icons
X-GNOME-AutoRestart=true
Icon=/usr/share/icons/gnome/32x32/apps/preferences-desktop-wallpaper.png
Categories=GTK;Utility;
Name[fr_FR]=nemo-autostart-with-gnome </code>
  * the activation should be visible into the menu of applications
  * select for autostart via gnome-tweak


====== Screen saver ======
<code># dnf install xscreensaver </code>
