In Linux various special files can be found under the directory <filename>/dev</filename>. These files are called device files and behave unlike ordinary files. The most common types of device files are for block devices and character devices. These files are an interface to the actual driver (part of the Linux kernel) which in turn accesses the hardware. Another, less common, type of device file is the named <firstterm>pipe</firstterm>. The most important device files are listed in the tables below.

The mouse can be used in both the Linux console (with gpm) and the X window environment. Normally, this is a simple matter of installing <filename>gpm</filename> and the X server itself. Both should be configured to use <filename>/dev/input/mice</filename> as the mouse device. The correct mouse protocol is named <userinput>exps2</userinput> in gpm, and <userinput>ExplorerPS/2</userinput> in X. The respective configuration files are <filename>/etc/gpm.conf</filename> and <filename>/etc/X11/xorg.conf</filename>.

Certain kernel modules must be loaded in order for your mouse to work. In most cases the correct modules are autodetected, but not always for old-style serial and bus mice<footnote> <para> Serial mice usually have a 9-hole D-shaped connector; bus mice have an 8-pin round connector, not to be confused with the 6-pin round connector of a PS/2 mouse or the 4-pin round connector of an ADB mouse. </para> </footnote>, which are quite rare except on very old computers. Summary of Linux kernel modules needed for different mouse types: <informaltable><tgroup cols="2"><thead> <row> <entry>Module</entry> <entry>Description</entry> </row> </thead><tbody> <row> <entry>psmouse</entry> <entry>PS/2 mice (should be autodetected)</entry> </row> <row> <entry>usbhid</entry> <entry>USB mice (should be autodetected)</entry> </row> <row> <entry>sermouse</entry> <entry>Most serial mice</entry> </row> <row> <entry>logibm</entry> <entry>Bus mouse connected to Logitech adapter card</entry> </row> <row> <entry>inport</entry> <entry>Bus mouse connected to ATI or Microsoft InPort card</entry> </row> </tbody></tgroup></informaltable> To load a mouse driver module, you can use the <command>modconf</command> command (from the package with the same name) and look in the category <userinput>kernel/drivers/input/mouse</userinput>.

Modern kernels give you the capability to emulate a three-button mouse when your mouse only has one button. Just add the following lines to <filename>/etc/sysctl.conf</filename> file.

54.

# 3-button mouse emulation
# turn on emulation
/dev/mac_hid/mouse_button_emulation = 1
# Send middle mouse button signal with the F11 key
/dev/mac_hid/mouse_button2_keycode = 87
# Send right mouse button signal with the F12 key
/dev/mac_hid/mouse_button3_keycode = 88
# For different keys, use showkey to tell you what the code is.

A standard installation for the i386 architecture, including all standard packages and using the default 2.6 kernel, takes up &std-system-size;MB of disk space. A minimal base installation, without the <quote>Standard system</quote> task selected, will take &base-system-size;MB.

57.

In both cases this is the actual disk space used <emphasis>after</emphasis> the installation is finished and any temporary files deleted. It also does not take into account overhead used by the file system, for example for journal files. This means that significantly more disk space is needed both <emphasis>during</emphasis> the installation and for normal system use.

58.

The following table lists sizes reported by aptitude for the tasks listed in tasksel. Note that some tasks have overlapping constituents, so the total installed size for two tasks together may be less than the total obtained by adding up the numbers.

59.

Note that you will need to add the sizes listed in the table to the size of the standard installation when determining the size of partitions. Most of the size listed as <quote>Installed size</quote> will end up in <filename>/usr</filename> and in <filename>/lib</filename>; the size listed as <quote>Download size</quote> is (temporarily) required in <filename>/var</filename>.

There is some overlap of the Laptop task with the Desktop environment task. If you install both, the Laptop task will only require a few MB additional disk space.
