111 111  The "-" implicates that it is a login shell. At example you need the login shell to use all your own variables. If you just change user etc. without it, it may happen that - at example - you don't have permissions to geht dconf work because of some variables still got owned by the previous user.

128 -
129 -==== Getting Help ====
130 -

132 -* Use <command> ~-~-help for quick help
133 -* Use apropos <keyword> to find related commands
134 -
135 -==== JDDD Issues ====

137 -* (((
138 - When starting the application, please check whether another instance is already running so that it does not open multiple windows or panels at the same time, which could cause an Out-Of-Memory error.
139 -If another instance is running, the new one should either close the existing instance safely or terminate the Java process **killall jddd **or via Task Manager.
140 -To open the Task Manager, press **Ctrl + Shift + Esc**.
141 -Alternatively, you can press **Ctrl + Alt + Delete** and select **Task Manager** from the menu or search in Apps.
142 -From there, you can find the running Java process and end it if necessary.

144 -**In case the Gnome graphic user interface is frozen, restart the X server by pressing the following 4 keys simultaneously: Ctr, Alt, SysReq, K. or Wndows taskbar**
145 -)))
76 +{{error}}
77 +But be aware that support is only for german/english. So if you don't understand something and theres a language like italian, korean etc. the chance is low to find someone who can understand this. So then we have to change the languages before and this needs a restart of the session.
