=== Brief Synopsis ===
+
=== X.Org ===
[http://icculus.org/virtualjaguar Virtual Jaguar] is a cross-platform Atari Jaguar emulator with a Qt UI. Currently the only one still in active development, it is being utilized by developers of Jaguar software in conjunction with real hardware tools like the [http://www.harmlesslion.com/cgi-bin/showprog.cgi?search=skunkboard Skunkboard]. Also the only Jaguar emulator that comes with it's own pack-in title: [http://reboot.atari.org/new-reboot/downfall.html Downfall]. One of the stated goals of the project is to increase the compatibility as much as possible; as a result, speed is sometimes sacrificed.

=== Features ===
+
In order to use a graphical environment it's necessary to install X.Org, which is an implementation of the X Window system.
* Multi-platform (currently Linux, Windows, and MacOS)
+
* Gamepad support
+
* Full screen support
+
* Good compatibility with existing Jaguar software
+
* Built-in facilities to assist developers in creating new software

=== Technical Features ===

Before we start it's a good idea to make sure that your system is configured correctly. If you've installed your kernel using the <code>binary</code> USE flag, chances are that your video card is already supported.
* Partially multithreaded implementation of processor cores

* Customized version of the UAE 68000 core

You should also find your IP address, because if X freezes and you need to get out of it, the safest way is to SSH in from another computer/smartphone/tablet and issue
* GUI is decoupled from emulator core

<console>

killall X

In order for Portage to know which [[Video | video]] card(s) you want to support, you'll need to add a line to your <code>[[make.conf | make.conf]]</code>.

<console>

# ##i##nano -w /etc/portage/make.conf
 +
...
 +
VIDEO_CARDS="intel"
 +
</console>
 +
 
 +
In the example above we're using Intel integrated graphics drivers. Examples of valid entries include <code>radeon</code> for AMD Radeon cards, and <code>nouveau</code> or <code>nvidia</code> for NVIDIA cards. If you haven't yet switched to the <code>desktop</code> profile it's a good idea to do it now.
 +
 
 +
Next comes the actual installation:
 +
<console>
 +
# ##i##emerge xorg-x11
 +
</console>

Now we need to test to make sure X.Org is working properly. To test it we will install twm, a simple window manager which has traditionally served as the standard window manager for X.Org. In Funtoo Linux it is included in the core X.Org meta-package <code>x11-apps/xinit</code>, but is not installed by default.
 +
 
 +
It is possible to install twm directly by merging <code>x11-wm/twm</code> but for the sake of this tutorial we will install the meta-package, which includes a few extra utilities which may come in handy. There are two ways to do this depending on whether you want it to be installed temporarily or permanently. If you just want it to test X.Org use the following command:
 +
<console>
 +
# ##i##USE="-minimal" emerge -1 xinit
 +
</console>
 +
 
 +
The <code>minimal</code> USE flag is used in some ebuilds to install the bare minimum needed to get a working system. By passing <code>USE="-minimal"</code> to the command line before <code>emerge</code>, we are telling Portage to disable the flag and install the complete package. The <code>-1</code> (<code>--oneshot</code>) following <code>emerge</code> tells Portage not to add the package to [[#Updating your system|<code>world</code>]]. This is useful when installing packages which are automatically pulled in as dependencies by other packages.
 +
 
 +
If you want the package installed permanently you will need to add a line to <code>package.use</code>:
 +
<console>
 +
# ##i##mkdir -p /etc/portage
 +
# ##i##echo x11-apps/xinit -minimal >> /etc/portage/package.use
 +
</console>
 +
 
 +
Next we reinstall <code>x11-apps/xinit</code>:
 +
<console>
 +
# ##i##emerge -1N xinit

</console>

Once that's done, we're able to finally test X.Org:
 +

<console>

# ##i##startx

X.Org

In order to use a graphical environment it's necessary to install X.Org, which is an implementation of the X Window system.

Before we start it's a good idea to make sure that your system is configured correctly. If you've installed your kernel using the binary USE flag, chances are that your video card is already supported.

You should also find your IP address, because if X freezes and you need to get out of it, the safest way is to SSH in from another computer/smartphone/tablet and issue

killall X

In order for Portage to know which video card(s) you want to support, you'll need to add a line to your make.conf.

# nano -w /etc/portage/make.conf
...
VIDEO_CARDS="intel"

In the example above we're using Intel integrated graphics drivers. Examples of valid entries include radeon for AMD Radeon cards, and nouveau or nvidia for NVIDIA cards. If you haven't yet switched to the desktop profile it's a good idea to do it now.

Next comes the actual installation:

# emerge xorg-x11

Now we need to test to make sure X.Org is working properly. To test it we will install twm, a simple window manager which has traditionally served as the standard window manager for X.Org. In Funtoo Linux it is included in the core X.Org meta-package x11-apps/xinit, but is not installed by default.

It is possible to install twm directly by merging x11-wm/twm but for the sake of this tutorial we will install the meta-package, which includes a few extra utilities which may come in handy. There are two ways to do this depending on whether you want it to be installed temporarily or permanently. If you just want it to test X.Org use the following command:

# USE="-minimal" emerge -1 xinit

The minimal USE flag is used in some ebuilds to install the bare minimum needed to get a working system. By passing USE="-minimal" to the command line before emerge, we are telling Portage to disable the flag and install the complete package. The -1 (--oneshot) following emerge tells Portage not to add the package to world. This is useful when installing packages which are automatically pulled in as dependencies by other packages.

If you want the package installed permanently you will need to add a line to package.use:

# mkdir -p /etc/portage
# echo x11-apps/xinit -minimal >> /etc/portage/package.use

Next we reinstall x11-apps/xinit:

# emerge -1N xinit

Once that's done, we're able to finally test X.Org:

# startx

If everything is well, a simple GUI along with an analog clock and a terminal will appear.

Keyboard/Mouse

If you have no keyboard/mouse input in x11, check if your kernel supports dev

zcat /proc/config.gz | grep EVDEV 
*

if your output is:

 CONFIG_INPUT_EVDEV=y 

Install xf86-input-evdev

emerge -avxf86-input-evdev
