16. fstab Configuration

Now let’s configure our /etc/fstab file.
We are interested on the lines that are relevant to optical drives and the floppy.
First of all see in which directories under “/mnt/” they are configured to be mounted and with Midnight Commander delete them.
Create under “/” directory a new directory “media” and in there create directories like these: 

cdrom0
cdrom1

depending on how many optical drives you have.

If you have a floppy create also the next directory: 

floppy0

The lines that the installed has placed in there are wrong and so you may delete them. In their place add the following ones: 

/dev/sr0 				/media/cdrom0   				udf,iso9660 	ro,user,noauto,iocharset=utf8,unhide   		0      	0
/dev/sr1 				/media/cdrom1   				udf,iso9660   	ro,user,noauto,iocharset=utf8,unhide   		0      	0
/dev/fd0 				/media/floppy0 					vfat   		user,noauto,iocharset=utf8   			0      	0

This is for our example where we have two optical drives and one floppy.

Note that your optical drives device names may be different from mine.

For your optical drives you may open later k3b and see what the names are. In the top left there will be a list with all your optical drives and their names as well.

Save the file and exit.

Now, we are finished with fstab as well.

17. Xorg Configuration 

Now let’s configure our X Server in order to have a nice refresh rate and 3D acceleration.
In your console type: 

mkdir /mnt/arch/etc/X11

Create a new file in there and save it with Western Locale encoding and a name
xorg.conf

Our xorg.conf is composed from three parts:

a. The first part is common for everyone. Copy and paste this one.

Section "Files"
    FontPath    "/usr/share/fonts/misc"

    Option        "ZAxisMapping"            "4 5"
    Option        "Emulate3Buttons"        "true"
EndSection 

b. The next part depends on our video card:

for nVidia σειρά GeForce5 and above

for ATi RADEON from X-XXXXX and above

for ATi RADEON till 9800XT

Section "Module"
    Load    "bitmap"
    Load    "dbe"
    Load    "ddc"
    Load    "dri"
    Load    "extmod"
    Load    "freetype"
    Load     "GLcore"
    Load    "glx"
    Load    "int10"
    Load    "record"

EndSection

Section "Device"
    Identifier    "My Graphics Card"
    Driver        "radeon"
    BusID        "PCI:2:0:0"
EndSection

In the last two ATi cases if you get an error try to change in the line: 

BusID "PCI:2:0:0"

The first number (here it is 2) to something else (such as 5) and try again. You might find the correct number by typing:

lspci | grep VGA

c. The third part depends on the type and model of your screen.
 
for TFT with DVI

Section "Monitor"
    Identifier    "My Monitor"
    Option        "DPMS"                 "True"
    Option         "DPI"               "96 x 96"
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Device        "My Graphics Card"
    Monitor        "My Monitor"
    Option        "UseEvents"            "true"
    DefaultDepth    24
    SubSection "Display"
        Depth        24
        Modes        "1280x1024"
        Viewport    0 0
    EndSubSection
    Option        "AddARGBGLXVisuals"        "true"
#    Option         "PixmapCacheSize"         "1000000"
#    Option         "AllowSHMPixmaps"         "0"
EndSection

Here be careful. In the line 

Modes "1280x1024"

You see what your screen resolution is. You should place your screen’s native resolution.

for CRT 

Section "Monitor"
    Identifier    "My Monitor"

EndSection

Here you need even more attention.
Again in the line: 

Modes "1280x960" "1152x864" "1024x768"

You can see which are your screen’s acceptable resolution. The first one should be what you want to use as a default.
BE CAREFUL!!

Don’t put in there a resolution that isn’t accepted from your screen.
Moreover in the following lines: 

HorizSync 30-115
VertRefresh 50-160

Read your screen’s specifications and place your horizontal and vertical refresh rates.

BE CAREFUL!!

If you use wrong values in here you may damage your screen.
Now save the file and close gedit.

Umount all the partitions you have previously mounted. 

cd /

Be careful. Here we umount with the reverse order we have previously mounted the partitions. Start from the folders and go to ther root “/”. 

umount /mnt/arch/mnt/repos

umount /mnt/arch

The directory arch is not needed any more so delete it. 

rmdir /mnt/arch

In that part the live CD isn’t needed any more. So exit everything that is running and reboot.

When computer reboots enter BIOS and select hard disk drive as the boot device.
