95By default, Xorg uses <c>evdev</c>, a generic input driver. You'll need to
96activate support for <c>evdev</c> by making a change to your kernel
97configuration. (Read the
98<uri link="/doc/en/kernel-config.xml">Kernel Configuration Guide</uri> if you
99don't know how to setup your kernel.)

223<title>Using HAL</title>
224<body>
225
226<p>
227Recent X server versions are designed to work out-of-the-box, with no need to
228manually configure Xorg's configuration files.
229</p>
230
231<p>
232You should first try <uri link="#using_startx">starting X</uri> without creating
233<path>/etc/X11/xorg.conf</path>.
234</p>
235
236<p>
237If Xorg won't start (if there's something wrong with the screen, or with your
238keyboard/mouse), then you can try fixing problems by using the right
239configuration files.
240</p>
241
242<p>
243By default, Xorg uses HAL (Hardware Abstraction Layer) to detect and configure
244devices such as keyboards and mice.
245</p>
246
247<p>
248HAL comes with many premade device rules, also called policies. These policy
249files are available in <path>/usr/share/hal/fdi/policy/</path>. Just find a few
250that suit your needs most closely and copy them to
251<path>/etc/hal/fdi/policy/</path>.
252</p>
253
254<impo>
255Do not edit the files in <path>/usr/share/hal/fdi/</path>! Just copy the ones
256you need, and edit them once they're placed in the proper <path>/etc</path>
257location.
258</impo>
259
260<p>
261For example, to get a basic working keyboard/mouse combination, you could copy
262the following files to <path>/etc/hal/fdi/policy/</path>:
263</p>
264
265<pre caption="Using HAL policy files">
266# <i>cp /usr/share/hal/fdi/policy/10osvendor/10-input-policy.fdi /etc/hal/fdi/policy</i>
267# <i>cp /usr/share/hal/fdi/policy/10osvendor/10-x11-input.fdi /etc/hal/fdi/policy</i>
268</pre>
269
270<p>
271There are several other HAL policies in <path>/usr/share/hal/fdi/</path> that
272may interest you, such as laptop configurations, storage device handling, power
273management, and more. Just copy any of the policies to
274<path>/etc/hal/fdi/policy/</path>.
275</p>
276
277<p>
278You can edit the policy files in <path>/etc/hal/fdi/policy</path> to your
279liking. You may want to make a few tweaks or to expose additional
280functionality. Let's go through an example of tweaking a HAL policy.
281</p>
282
283<p>
284One very convenient trick is to kill the X server entirely by pressing
285Ctrl-Alt-Backspace. This is useful when your X server is malfunctioning, frozen,
286etc. It's not as extreme as rebooting the whole machine with Ctrl-Alt-Del.
287</p>
288
289<p>
290Recent X server versions disabled this key combination by default. However, you
291can reenable it by copying <path>10-x11-input.fdi</path> to
292<path>/etc/hal/fdi/policy</path> and editing it. You'll need to add just one
293line to the appropriate section, as shown below:
294</p>
295
296<pre caption="Editing 10-x11-input.fdi">
297<comment>(Open the file in your preferred editor)</comment>
298# <i>nano -w /etc/hal/fdi/policy/10-x11-input.fdi</i>
299<comment>(Find the "input.keys" section)</comment>
300&lt;match key="info.capabilities" contains="input.keys"&gt;
301<comment>(Add the "terminate" merge string as shown)</comment>
302&lt;match key="info.capabilities" contains="input.keys"&gt;
303 &lt;merge key="input.x11_driver" type="string"&gt;keyboard&lt;/merge&gt;
304 <i>&lt;merge key="input.xkb.options" type="string"&gt;terminate:ctrl_alt_bksp&lt;/merge>&gt;</i>
305 &lt;match key="/org/freedesktop/Hal/devices/computer:system.kernel.name"
306 string="Linux"&gt;
307 &lt;merge key="input.x11_driver" type="string"&gt;evdev&lt;merge&gt;
308 &lt;/match&gt;
309 &lt;/match&gt;
310</pre>
311
312<p>
313There, now you have a handy way of killing an unresponsive X server. This is
314useful when programs have frozen your display entirely, or when configuring and
315tweaking your Xorg environment. Be careful when killing your desktop with this
316key combination -- most programs really don't like it when you end them this
317way, and you may lose some (or all) of what you were working on.
318</p>
319
320<p>
321Hopefully just working with the HAL policy files results in a working X desktop.
322If Xorg still won't start, or there's some other problem, then you'll need to
323manually configure <path>xorg.conf</path> as shown in the next section.

333Configuring <path>xorg.conf</path> should be seen as a "last resort" option. It
334really desirable to run without one if possible, and to do all your
335configuration via HAL policy files. If you still can't get a working

257Xorg provides a tool called <c>xorgconfig</c> which will ask you for various
258information regarding your system (graphical adapter, keyboard, ...). Based on
259your input it will create a <path>xorg.conf</path> file.

428If your mouse isn't working, you will first need to find out if it is detected
429by the kernel at all. Mice are (device-wise) seen as
430<path>/dev/input/mouse0</path> (or <path>/dev/input/mice</path> if you want to
431use several mice). In some cases <path>/dev/psaux</path> is used. In either
432case you can check if the devices do represent
433your mouse by checking the output of those files when you move your mouse. You
434will usually see some junk on your screen. To end the session press
435<c>Ctrl-C</c>.
