141 <title>Downloading KDE Plasma</title>
142
143 <para>
144 The easiest way to get the KDE Plasma packages is to use a single
145 <command>wget</command> to fetch them all at once:
146 </para>
147
148<screen><userinput>url=https://download.kde.org/stable/plasma/&plasma-version;/
149wget -r -nH -nd -A '*.xz' -np $url</userinput>
150<literal>
151The options used here are:
152 -r recurse through child directories
153 -nH disable generation of host-prefixed directories
154 -nd do not create a hierarchy of directories
155 -A '*.xz' just get the *.xz files
156 -np don't get parent directories</literal></screen>

505 The X session starts on the first unused virtual terminal, normally vt7.
506 You can switch to another vt<emphasis>n</emphasis> simultaneously
507 pressing the keys Ctrl-Alt-F<emphasis>n</emphasis>
508 (<emphasis>n</emphasis>=1, 2, ...). To switch back to the X session,
509 normally started at vt7, use Ctrl-Alt-F7. The vt where the command
510 <command>startx</command> was executed will display many messages,
511 including X starting messages, applications automatically started with
512 the session, and eventually, some warning and error messages. You may
513 prefer to redirect those messages to a log file, which not only will keep
514 the initial vt uncluttered, but can also be used for debugging purposes. This
515 can be done starting X with:
