 The procedure for loading ondemand-applications may seem a bit round-about; however it is more convenient, indeed, than having to load them from the terminal. Of course, one would [[dcore:contributing|wish]] for a fully automated process. The procedure for loading ondemand-applications may seem a bit round-about; however it is more convenient, indeed, than having to load them from the terminal.

 +==== Accessing the menus via keyboard ====
 +
 +It is useful to have access to either menu via a keyboard short-cut. This is especially helpful in case that LXPanel should become invisible due to different monitor sizes.
 +
 +Add the following to the ''<keyboard>''-section of '~/.config/openbox/rc.xml':
 +<code>
 +    <keybind key="C-Escape">
 +      <action name="ShowMenu">
 +        <menu>root-menu</menu>
 +      </action>
 +    </keybind>
 +    <keybind key="C-F1">
 +      <action name="Execute">
 +        <command>lxpanelctl menu</command>
 +      </action>
 +    </keybind>
 +</code>
 +This will bind Ctrl-Escape to the Openbox main menu and Ctrl-F1 the "start" menu of LXPanel.

-===== Re-booting =====+===== LXPanel settings =====
  
-Notice that the Logout entry in the "start" menu is not functional. The *Core exit command may be launched from the main menu or via the LXPanel "start" menu under System Tools.+By right-clicking on the panel, on gains access to the panel settings. From there, one may choose to add, remove or configure panel items.
  
-====Exit button====+==== Log-out ====
  
-FIXME +The Logout entry in the "start" menu can be set to *Core's exit in the advanced settings to "/usr/local/bin/exittc".
- +
-The button for log-out provided by LXDE should be replaced by the exit button by *Core. The LXDE log-out dialogue will remain available through the main LXDE-menu. +
- +
-  *Right-click on the taskbar and choose to add or remove panel items. +
-  *Add an application launch bar and edit its content to be the exit-command from the system tools menu. +
- +
-One probably wants to delete the application launch bar containing the screen-lock and LXDE-exit buttons.+

-=====Further settings===== 
  
-Some sporadic notes about useful settings for the LXDE-desktop. +==== Resource monitor, LXTask ====
- +
-==== LXDE-settings ==== +
-The [[http://lxlinux.com|LXDE-Openbox Guide]] is a pretty useful reference for many scenarios. +
- +
-==== Openbox settings ==== +
-Since LXDE is based on Openbox, it may be helpful to consider the [[https://urukrama.wordpress.com/openbox-guide|Openbox guide]] by urukrama. +
- +
- +
-====Function keys==== +
- +
-LXDE intercepts ''F11'' before any application and interprets it as command to maximize and un-decorate the window. It is more common to have this function key interpreted by the application itself. +
- +
-The key binding can be changed in '~/.config/openbox/lxde-rc.xml'. Unfortunately the respective section comes as quite an unordered muddle which makes XML particularly hard to read. Nevertheless, the following will lay the binding to Ctrl+Shift+F11 instead. (Searching for "ToggleFullscreen" will get you to the right place.) +
- +
-<code> +
-<keybind key="C-S-F11"><action name="ToggleFullscreen"/></keybind> +
-</code>+
  
-==== Resource monitor, LXTask ==== +LXPanel provides a resource-monitor add-in which is quite useful by itself. Furthermore, its standard action upon clicking is to launch LXTask which give a quite complete over-view of running processes. It is installed through the ''lxtask'' package. Alternatively, one may want to link the clicking action to the System Stats entry from *Core's main menu. This is achieved by adding "/usr/local/bin/stats" in the settings.

-==== Screen settings and external monitor ==== +
-The built-in 'lxrandr' does not seem to work on all machines. Occasionally, it only proclaims its inability to find information about the monitor. [[http://christian.amsuess.com/tools/arandr/|Arandr]] is an even better substitute which can be imported and loaded without any issues. It installs an entry in the settings menu.+
  
-In case that Lxpanel should become invisible due to different monitor sizes, the main menu can still be accessed by pressing Ctrl+Esc.+==== LXPanel menu entries and buttons for suspending to RAM or disk ====
  
-==== Menu entries and panel buttons for suspending to RAM or disk ==== +If [[dcore:suspending|suspending to RAM or disk]] works then one may want to make it easily available through a panel button. For that matter, one must first create suitable menu entries.
-If [[dcore:suspending|suspending to RAM or disk]] works then one may want to make it easily available through a panel button. For that matter, one must first create suitable menu entries after which it is a trivial task of adding them to the application starter containing already the [[dcore:migrating_from_flwm_to_lxde#exit_button|exit button]].+
  
-First, create the directory '~/.local/share/pixmaps/' and download a [[http://wiki.tinycorelinux.net/_media/dcore:exittc_green.png|green]] and [[http://wiki.tinycorelinux.net/_media/dcore:exittc_green.png|red]] variant of the original blue icon file for the exit button into it.+First, create the directory '~/.local/share/pixmaps/' and download a [[http://wiki.tinycorelinux.net/_media/dcore:exittc_green.png|green]] and [[http://wiki.tinycorelinux.net/_media/dcore:exittc_red.png|red]] variant of the original blue icon file for the exit button into it.
  
 Then create two files ''~/.local/share/applications/pm-{suspend,hibernate}.desktop'' with the following content, respectively. Adapt the path if a different user name applies. If applicable, one may want to use ''pm-suspend-hybrid'' instead of simple ''pm-suspend''. Then create two files ''~/.local/share/applications/pm-{suspend,hibernate}.desktop'' with the following content, respectively.

 + 
 +Afterwards, it is a trivial task of adding an application starter to the LXPanel items with these menu entries. 
 + 
 +==== LXPanel button for quick shutdown with automatic backup ==== 
 + 
 +In the same light, one may want to creat a blue exit button in the panel that performs a backup of 'mydata.tgz' and shuts the machine down. 
 + 
 +First, create an //executable// file '~/.local/bin/backup-exittc.sh' with the following content: 
 +<code> 
 +#!/bin/sh 
 +filetool.sh -b  
 +exitcheck.sh shutdown 
 +</code> 
 + 
 +Then create a menu entry via '~/.local/share/applications/backup-exittc.desktop', again adapting the path to the home folder if applicable. 
 +<code> 
 +[Desktop Entry] 
 +Name=Exit w/ Backup 
 +Exec=/home/tc/.local/bin/backup-exittc.sh 
 +Icon=/usr/local/share/pixmaps/exittc.png 
 +Type=Application 
 +Categories=System; 
 +</code> 
 + 
 +Finally, add the menu entry to the application launcher in LXPanel. 
 +===== Openbox settings ===== 
 + 
 +It may be helpful to consider one of the many Openbox guides available over the internet. As usual, the [[https://wiki.archlinux.org/index.php/openbox|Arch Wiki]] features a very complete over-view.

-Although strictly speaking an issue of Openbox, this quick guide is included here nevertheless. Scrolling on the desktop with either mouse wheel or (inadvertedly) the touchpad is interpreted as a command to switch desktops.
