372</p> 360displays, keyboards, and mice.

375You should first try <uri link="#using_startx">starting X</uri> without creating 364You should first try <uri link="#using_startx">starting X</uri> without editing

377</p> 366then you'll need to manually configure Xorg as shown in the next section.
378
379<p> 367</p>
380If Xorg won't start (if there's something wrong with the screen, or with your
381keyboard/mouse), then you can try fixing problems by using the right
382configuration files.
383</p>
384 368
385<p>
386By default, Xorg uses HAL (Hardware Abstraction Layer) to detect and configure
387devices such as keyboards and mice.
388</p>
389
390<p>
391HAL comes with many premade device rules, also called policies. These policy
392files are available in <path>/usr/share/hal/fdi/policy/</path>. Just find a few
393that suit your needs most closely and copy them to
394<path>/etc/hal/fdi/policy/</path>.
395</p>
396
397<impo>
398Do not edit the files in <path>/usr/share/hal/fdi/</path>! Just copy the ones
399you need, and edit them once they're placed in the proper <path>/etc</path>
400location.
401</impo>
402
403<p>
404For example, to get a basic working keyboard/mouse combination, you could copy
405the following files to <path>/etc/hal/fdi/policy/</path>:
406</p>
407
408<pre caption="Using HAL policy files">
409# <i>cp /usr/share/hal/fdi/policy/10osvendor/10-input-policy.fdi /etc/hal/fdi/policy</i>
410# <i>cp /usr/share/hal/fdi/policy/10osvendor/10-x11-input.fdi /etc/hal/fdi/policy</i>
411</pre>
412
413<p>
414There are several other HAL policies in <path>/usr/share/hal/fdi/</path> that
415may interest you, such as laptop configurations, storage device handling, power
416management, and more. Just copy any of the policies to
417<path>/etc/hal/fdi/policy/</path>.
418</p>
419
420<impo>
421Remember, <e>every</e> time you finish making changes to HAL policy files, you
422need to restart the HAL daemon by running <c>/etc/init.d/hald restart</c>.
423</impo>
424
425<p>
426You can edit the policy files in <path>/etc/hal/fdi/policy</path> to your
427liking. You may want to make a few tweaks or to expose additional
428functionality. Let's go through an example of tweaking a HAL policy.
429</p>
430
431<p>
432One very convenient trick is to kill the X server entirely by pressing
433Ctrl-Alt-Backspace. This is useful when your X server is malfunctioning, frozen,
434etc. It's not as extreme as rebooting the whole machine with Ctrl-Alt-Del.
435</p>
436
437<p>
438Recent X server versions disabled this key combination by default. However, you
439can reenable it by copying <path>10-x11-input.fdi</path> to
440<path>/etc/hal/fdi/policy</path> and editing it. You'll need to add just one
441line to the appropriate section, as shown below:
442</p>
443
444<pre caption="Editing 10-x11-input.fdi">
445<comment>(Open the file in your preferred editor)</comment>
446# <i>nano -w /etc/hal/fdi/policy/10-x11-input.fdi</i>
447<comment>(Find the "input.keys" section)</comment>
448&lt;match key="info.capabilities" contains="input.keys"&gt;
449<comment>(Add the "terminate" merge string as shown)</comment>
450&lt;match key="info.capabilities" contains="input.keys"&gt;
451 &lt;merge key="input.x11_driver" type="string"&gt;keyboard&lt;/merge&gt;
452 <i>&lt;merge key="input.xkb.options" type="string"&gt;terminate:ctrl_alt_bksp&lt;/merge&gt;</i>
453 &lt;match key="/org/freedesktop/Hal/devices/computer:system.kernel.name"
454 string="Linux"&gt;
455 &lt;merge key="input.x11_driver" type="string"&gt;evdev&lt;merge&gt;
456 &lt;/match&gt;
457 &lt;/match&gt;
458</pre>
459
460<p>
461Once you're done, run <c>/etc/init.d/hald restart</c> so that HAL picks up your
462changes.
463</p>
464
465<p>
466There, now you have a handy way of killing an unresponsive X server. This is
467useful when programs have frozen your display entirely, or when configuring and
468tweaking your Xorg environment. Be careful when killing your desktop with this
469key combination -- most programs really don't like it when you end them this
470way, and you may lose some (or all) of what you were working on.
471</p>
472
473<p>
474Hopefully just working with the HAL policy files results in a working X desktop.
475If Xorg still won't start, or there's some other problem, then you'll need to
476manually configure <path>xorg.conf</path> as shown in the next section.

511Xorg itself is able to guess most parameters for you. In most cases, you
512will only have to change some lines to get the resolution you want up and
513running. If you are interested in more in-depth tweaking, be sure to check the
514resources at the end of this chapter. But first, let us generate a (hopefully

535If all goes well, you should see a simple black and white pattern. Verify if
536your mouse works correctly and if the resolution is good. You might not be able
537to deduce the exact resolution, but you should be able to see if it's too low.
538You can exit any time by pressing Ctrl-Alt-Backspace.

624sections in your <path>xorg.conf</path> configuration. First of all, you have 461sections in your <path>xorg.conf.d</path> configuration. First of all, you have

632What happens is that Xorg checks the settings of <c>HorizSync</c> and
