<title>The Graphical Installer</title>

The graphical version of the installer is only available for a limited
|
| 9 |
number of architectures, including &arch-title;. The functionality of
|
| 10 |
the graphical installer is essentially the same as that of the regular
|
| 11 |
installer as it basically uses the same programs, but with a different
|
| 12 |
frontend.

Although the functionality is identical, the graphical installer still has
|
| 17 |
a few significant advantages. The main advantage is that it supports more
|
| 18 |
languages, namely those that use a character set that cannot be displayed
|
| 19 |
with the regular <quote>newt</quote> frontend. It also has a few usability
|
| 20 |
advantages such as the option to use a mouse, and in some cases several
|
| 21 |
questions can be displayed on a single screen.

The graphical installer is available with all CD images and with the
|
| 26 |
hd-media installation method. As the graphical installer uses a separate
|
| 27 |
(much larger) initrd than the regular installer, it has to be booted using
|
| 28 |
<userinput>installgui</userinput> instead of <userinput>install</userinput>.
|
| 29 |
Analogous, the expert and rescue modes are booted using
|
| 30 |
<userinput>expertgui</userinput> and <userinput>rescuegui</userinput>
|
| 31 |
respectively.

The mini ISO image can be downloaded from a Debian mirror as described

booted just using <userinput>install</userinput>. There is no graphical
|

installer image that can be netbooted.

The graphical installer requires significantly more memory to run than
|
| 63 |
the regular installer: &minimum-memory-gtk;. If insufficient memory is
|
| 64 |
available, it will automatically fall back to the regular
|
| 65 |
<quote>newt</quote> frontend.

You can add boot parameters when starting the graphical installer, just as
|
| 70 |
with the regular installer. One of those parameters allows you to configure
|
| 71 |
the mouse for left-handed use. See <xref linkend="boot-parms"/> for valid
|
| 72 |
parameters.

As already mentioned, the graphical installer basically works the same as
|
| 81 |
the regular installer and thus the rest of this manual can be used to guide
|
| 82 |
you through the installation process.

If you prefer using the keyboard over the mouse, there are two things you
|
| 87 |
need to know. To expand a collapsed list (used for example for the selection
|
| 88 |
of countries within continents), you can use the <keycap>+</keycap> and
|
| 89 |
<keycap>-</keycap> keys. For questions where more than one item can be
|
| 90 |
selected (e.g. task selection), you first need to tab to the
|
| 91 |
<guibutton>Continue</guibutton> button after making your selections; hitting
|
| 92 |
enter will toggle a selection, not activate <guibutton>Continue</guibutton>.

To switch to another console, you will also need to use the
|
| 97 |
<keycap>Ctrl</keycap> key, just as with the X Window System. For example,
|
| 98 |
to switch to VT1 you would use: <keycombo> <keycap>Ctrl</keycap>
|
| 99 |
<keycap>Left Alt</keycap> <keycap>F1</keycap> </keycombo>.

Etch is the first release that includes the graphical installer and uses
|
| 109 |
some relatively new technology. There are a few known issues that you may
|
| 110 |
run into during the installation. We expect to be able to fix these issues
|
| 111 |
for the next release of &debian;.

Information on some screens is not nicely formatted into columns as it
|
| 119 |
should be. The most obvious example is the first screen where you select
|
| 120 |
your language. Another example is the main screen of partman.

Typing some characters may not work and in some cases the wrong character
|
| 126 |
may be printed. For example, "composing" a character by typing an accent and
|
| 127 |
then the letter over/under which the accent should appear does not work.

You should not switch to a different console while the installer is busy;
|
| 138 |
this may cause the frontend to crash. The frontend will be restarted
|
| 139 |
automatically, but this may still cause problems with the installation.
|
| 140 |
Switching to another console while the installer is waiting for input
|
| 141 |
should work without causing any problems.

Support for creating encrypted partitions is limited as it is not possible
|
| 147 |
to generate a random encryption key. It is possible to set up an encrypted
|
| 148 |
partition using a passphrase as encryption key.
