1. Download and install a dark theme for your distribution. Beware
there are many broken and outdated themes for gtk2. So you have to try
a few. For example NOX.
2. Start the IDE with:
GTK2_RC_FILES=/usr/share/themes/NOX/gtk-2.0/gtkrc ./lazarus
3. Set the source editor colors:
 Tools / Options / Display / Editor / Display / Colors
3.1 Change Default to Twilight.
