xorg is the public, open source implementation of the X11 X Windows system. Basically, if you want a GUI atop Arch, you will want xorg.

Installing xorg

Before beginning, make sure you do the following:

- Make sure that pacman is configured and refreshed. - If you are running another x-server you can close it now. ctrl+alt+backspace - Make a note about third party drivers (e.g., nVidia or ATI drivers).

Installing xorg is easy: # pacman -S xorg

If xorg installed ok, it's time to make xorg.conf with xorgconfig.

Configuring xorg

Before you can run xorg, you need to configure it so that it knows about your graphics card, monitor, mouse and keyboard. There are two main routes: xorgconfig or hwd.

xorgconfig

To start up xorgconfig: xorgconfig

This will generate a new xorg.conf.

Answer the questions and the program makes the file for you. NB watch out for the question about your mouse device. The default device according to xorgconfig is /dev/mouse. However, you should change this to /dev/input/mice. Otherwise, you may encounter the common problem of X freezing on when executed.

This program is not really good but it's a start and you can fill in special stuff manually afterwards.

hwd

hwd is a tool written by users in the Arch Linux community. It's basically a hardware detection tool that has multiple uses, one of which is setting up an X server. Fortunately, hwd is much more streamlined than xorgconf and doesn't require any input at all.

First, you need to install it: pacman -S hwd

Then you need to run it (as root) with the -x argument that tells it to generate an xorg.conf hwd -x

This will not overwrite any existing xorg configuration file and instead creates a new file /etc/X11/xorg.conf.hwd (Alternatively, you could have used -xa flag which would have overwritten straight to xorg.conf). To use this, you must manually rename it: mv xorg.conf.hwd xorg.conf

NB If you have an existing xorg.conf, you may wish to back up prior to running this command.

Post-editing

You may wish to edit the config after it's been generated. To open in your favourite text-editor, such as Vim (you need root privilages): vim /etc/X11/xorg.conf

Some people may need to tweak their display size. In the section “Monitor” put in your display size in mm under the VertRefresh:

VertRefresh 50-70 DisplaySize 305 230

If you wish to use 3rd party graphics drivers, do check first that the X server runs ok first. Xorg should run smoothly without official drivers, they are typically only needed for advanced features such as 3D accelerated rendering for games, dual-screen setups, and TV-out.

Running Xorg

This is done simply by typing: startx

The default X environment is rather bare, and you will typically seek to install window managers or desktop environments to supplement X.

If a problem occurs, then view the log at /var/log/Xorg.0.log. Be on the lookout for any lines beginning with (EE) which represent errors, and also (WW) which are warnings that could indicate other issues.

X startup (/usr/X11R6/bin/startx) tweaking

for X's option reference see man Xserver

The following options have to be appended to the variable “defaultserverargs” in the /usr/X11R6/bin/startx file.

prevent X from listening on tcp: -nolisten tcp

getting rid of the gray weave pattern while X is starting and let X set a black root window: -br

enable deferred glyph loading for 16 bit fonts: -deferglyphs 16
