<question>
<para>How do I change the screen resolution?</para>
</question>
<answer>
<para>Use <keycombo
action="simul">&Ctrl;&Alt;<keycap>+</keycap></keycombo> and <keycombo
action="simul">&Ctrl;&Alt;<keycap>-</keycap></keycombo> to cycle through
the resolutions you have defined in <filename>XF86Config</filename> (maybe under
<filename class="directory">/etc/X11</filename>; poke around first).
If you prefer to get your hands dirty, you can always edit the file
directly.  By placing your favorite resolution at the beginning (or
making it the only one listed), &X-Window; will always start up with that
resolution.
<caution><para>Always make a backup copy of your <filename>XF86Config</filename> file
<emphasis>before</emphasis> you start editing it.  Errors in this file
can render &X-Window; unusable.</para></caution>
<note><para>These instructions are only valid if you are running
version 3.3.x of the XFree86 server.  If you are running XFree86 4.x,
you must consult with the <ulink url="http://xfree.org">XFree86(TM):
Home Page</ulink>.</para></note></para>

<question>
<para>How do I change the color depth?</para>
</question>
<answer>
<para>There is no way you can do this on the fly.  You can either
start &X-Window; using <command>startx <option> -bpp
<replaceable>number</replaceable></option></command> where
<replaceable>number</replaceable> can be 8, 16, 24 or 32, depending on
the depth you want. Alternatively, if you are using
<application>xdm</application>/&kdm;, you
need to edit
<filename>/etc/X11/xdm/Xservers</filename> (may vary) and enter
<userinput>:0 local /usr/X11R6/bin/X -bpp 16</userinput> for 16 bit color
depth.</para>
<para>You can also edit the <filename>XF86Config</filename> file and add a line
like <userinput>DefaultColorDepth
<replaceable>number</replaceable></userinput> to Section "Screen".
The next time you start X, it will run with the newly-configured color
depth.</para>

<question>
<para>What can I do if I am using a 2-button mouse?</para>
</question>
<answer>
<para>Go buy a 3-button one, or use third button emulation.  The third
button is emulated by pressing both the &LMB; and the &RMB;
together.  You would need to enable <option>Emulate3Buttons</option>
in your <filename>XF86Config</filename> file. </para>

<question>
<para>What is a "sticky" window?</para>
</question>
<answer>
<para>In a virtual desktop environment with multiple virtual desktops, a
"sticky" window will stay put on the screen when you switch between
desktops, as if sticking to the glass of the screen.
<application>Xclock</application> is a typical candidate for sticking,
as you need to run only one instance of it, and it always stays with
you. </para>

<question>
<para>How do I replace the "X" mouse pointer with an arrow?</para>
</question>
<answer>
<para>The various types of cursor available in X are defined in
<filename class="headerfile">X11/cursorfont.h</filename>.  You can
change it using <command>xsetroot -cursor_name
<replaceable>name_of_cursor</replaceable></command>.  For example, I
have the following in my <filename>.Xclients</filename>:</para>
<screen>
xsetroot -cursor_name left_ptr
</screen>
<para>This will create the common left-angled pointer.  To see other
alternatives, type <command>xfd -fn cursor</command>.  And of course,
do not forget that <command>man xsetroot</command> is your
friend.</para>

<question>
<para>How do I extract/install diff files?</para>
</question>
<answer>
<para>To generate a context-diff suitable for patching, use
<command>diff -u <replaceable>old-file new-file</replaceable> &gt;
<replaceable>patchfile</replaceable></command>.  To apply the diff to
a file (<abbrev>i.e.</abbrev> "patch the file"), execute
<command>patch &lt; <replaceable>patchfile</replaceable></command>.</para>
