15 <para>How do I change the screen resolution?</para>
16 </question>
17 <answer>
18 <para>Use <keycombo
19 action="simul">&Ctrl;&Alt;<keycap>+</keycap></keycombo> and <keycombo
20 action="simul">&Ctrl;&Alt;<keycap>-</keycap></keycombo> to cycle through
21 the resolutions you have defined in <filename>XF86Config</filename> (maybe under
22 <filename class="directory">/etc/X11</filename>; poke around first).
23 If you prefer to get your hands dirty, you can always edit the file
24 directly.  By placing your favorite resolution at the beginning (or
25 making it the only one listed), &X-Window; will always start up with that
26 resolution.
27 <caution><para>Always make a backup copy of your <filename>XF86Config</filename> file
28 <emphasis>before</emphasis> you start editing it.  Errors in this file
29 can render &X-Window; unusable.</para></caution>
30 <note><para>These instructions are only valid if you are running
31 version 3.3.x of the XFree86 server.  If you are running XFree86 4.x,

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

64 <answer>
65 <para>Go buy a 3-button one, or use third button emulation.  The third
66 button is emulated by pressing both the &LMB; and the &RMB;
67 together.  You would need to enable <option>Emulate3Buttons</option>
68 in your <filename>XF86Config</filename> file. </para>

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

93 <command>diff -u <replaceable>old-file new-file</replaceable> &gt;
94 <replaceable>patchfile</replaceable></command>.  To apply the diff to
95 a file (<abbrev>i.e.</abbrev> "patch the file"), execute
