Reprint: Ubuntu boot directly into the command line mode

Recently installed ubuntu12.04 to use, it is inconvenient to enter the Unity interface and enter the command line every time.

If you do not need an interface, you can set it up to enter command line mode.

Today, we offer a better method in two. After I test both methods can be used.

"1"

Command:

sudo gedit/etc/default/grub

Find this line

grub_cmdline_linux_default= "Quiet Splash"

Change into

grub_cmdline_linux_default= "Quiet Splash Text"

In the input command:
sudo update-grub

The tty1 is automatically entered after the boot.

(The following method is recommended, because you can choose to enter the command line or interface mode when booting)

"2"

sudo chmod +w/boot/grub/grub.cfg #增加可写权限

sudo gedit/boot/grub/grub.cfg #编辑配置文件

Will find a facet of this text:

Menuentry ' Ubuntu,linux 3.2.0-24-generic-pae '--class Ubuntu--class gnu-linux--class GNU--class os {
Recordfail
Gfxmode $linux _gfx_mode
Insmod Gzio
Insmod Part_msdos
Insmod ext2
Set root= ' (Hd0,msdos8) '
Search--no-floppy--fs-uuid--set=root 689a61a1-06fd-4ffe-95d7-8671e97bbe81
Linux/boot/vmlinuz-3.2.0-24-generic-pae root=uuid=689a61a1-06fd-4ffe-95d7-8671e97bbe81 ro quiet Splash $vt _handoff
Initrd/boot/initrd.img-3.2.0-24-generic-pae
}

Copy the text above and paste it back in.

Modify some settings. Modified as follows

Menuentry ' ubuntu,linux 3.2.0-24-generic-pae (Command mode) '--class Ubuntu--class gnu-linux--class GNU--class os {
Recordfail
Gfxmode $linux _gfx_mode
Insmod Gzio
Insmod Part_msdos
Insmod ext2
Set root= ' (Hd0,msdos8) '
Search--no-floppy--fs-uuid--set=root 689a61a1-06fd-4ffe-95d7-8671e97bbe81
Linux/boot/vmlinuz-3.2.0-24-generic-pae root=uuid=689a61a1-06fd-4ffe-95d7-8671e97bbe81 ro Text
Initrd/boot/initrd.img-3.2.0-24-generic-pae

}

That's it. My physical machine is installed directly, when the boot has a menu, directly select Ubuntu,linux 3.2.0-24-generic-pae (Command mode) this option can be

If the virtual machine is installed, perhaps the boot is no option (I use the VM virtual machine installed by default there is no menu selected) The workaround is as follows:

When booting up, the Grub menu system is hidden by default, removing the hidden need to do the following

You need to modify/etc/default/grub one of the lines (find it yourself, right in front), command: sudo gedit/etc/default/grub

Grub_hidden_timeout=0 (default is 0, repair to be modified to a value greater than 0, such as 10)

Quit after saving!

To execute the command again:

sudo update-grub

OK, the settings are complete.

The last of the friendly tips.

(If you encounter a file such as open, or save, then the permissions are not enough Baidu chmod command to modify the permissions can be, vi in fact, the editor is very good ~ ~ ~ ~ because it has not yet played clear ~ ~ ~ ~ ~ with gedit)
