<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>

<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>/&tdm;, 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>

<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>
