Editing PsionLX (section)

=== Theme, settings and keyboard ===

The <code>psion-theme</code> package has two halves. The GTK half is a <code>gtkrc</code> using the "mist" engine, with a <code>#E2E2E2</code> base and <code>#a1b6d7</code> for the clock and button bar. The window manager half is 20 PNG images plus <code>theme.xml</code> and <code>theme.desktop</code>. Psion derived it from the Blondie Matchbox theme and never renamed it: <code>theme.xml</code> still opens <code><theme name="blondie" author="Matthew Allum - mallum@handhelds.org"</code>, with <code>bgcol</code> and <code>dockcol</code> set to <code>#a1b6d7</code>.<ref name="oe-tree" />

Psion's XSettings override is four lines. It sets the double-click timing, turns Matchbox compositing off and selects the theme:<ref name="oe-tree" />

<pre>
Net/DoubleClickTime:I:600
Net/DoubleClickDistance:I:7
MATCHBOX/COMPOSITE:S:off
Net/ThemeName:S:psion
</pre>

The session also sets <code>LANG=en_GB</code>, sets <code>GPE_PRETEND_STYLUS=1</code>, and loads Psion's keyboard map for the machine, <code>xmodmap-netbookpro</code>. Psion's Matchbox keyboard bindings are:<ref name="oe-tree" />
