Configure X

The next thing you'll probably want is a graphical user interface, which is what most people are comfortable with. So let's being emerging xwindows, which will provide a framework you can extend with a desktop manager. Before doing this emerge, make sure the hal USE flag has been set in your /etc/make.conf. New versions of X will use udev for hardware detection, but at this time these versions and their dependencies are still masked in portage.

$ sudo emerge -av xorg-x11

---

Note: at this point, xorg will pull in the video drivers for whatever you have specified for the VIDEO_CARDS value in your /etc/make.conf. If you are electing to use the nvidia closed-source drivers, be sure to build them with the gtk USE flag in order to install a useful graphical driver settings utility.

If you are installing Gentoo onto a laptop with a synaptics touchpad, you may also want to include synaptics as one of the values for the INPUT_DEVICES setting.

---

There should be a lot of packages that get installed with X, so feel free to go have a coffee. After the emerge has finished, we now need to configure xorg. First, lets update our environment.

$ sudo env-update && source /etc/profile

Start HAL and configure it to start when the system starts up.

$ sudo /etc/init.d/hald start
$ sudo rc-update add hald default

There are 2 policy configuration files that need to be set for HAL to work properly.

$ sudo cp /usr/share/hal/fdi/policy/10osvendor/10-input-policy.fdi /etc/hal/fdi/policy
$ sudo cp /usr/share/hal/fdi/policy/10osvendor/10-x11-input.fdi /etc/hal/fdi/policy

In a perfect world, X will work without any configuration settings. Sadly the world isn't often perfect, so you may need to edit your /etc/X11/xorg.conf file manually.

$ sudo nano -w /etc/X11/xorg.conf

/etc/X11/xorg.conf

This file is an example dual-display configuration using nvidia's proprietary closed-source drivers.
