linux ubuntu 11.10 开机进入命令行 设置过程

Is it possible to disable GUI / X at boot time?
So many Ubuntu 11.10 Desktop edition users are asking the same question. On my ubuntu machine I have done following steps to disable GUI boot in ubuntu 11.10

Step 1 First update your repository by
running

sudo apt-get update

Step 2 There is some bug in old version of lightdm, so we need to upgrade the same. To do so run,

sudo apt-get install lightdm

Step 3 Now we have to modify grub config.

Step 3a Open /etc/default/grub with your faviourite editor and change

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="text"

Step 3b Also comment GRUB_HIDDEN_TIMEOUT=0 This line is for unhiding the GRUB menu





Step 4 Now we will upgrade GRUB configuration

sudo update-grub

Step 5 Ubuntu 11.10 Desktop edition use lightdm for GUI. We need to disable the same

sudo update-rc.d -f lightdm remove

Step 6 Now restart your machine. Voilla you will be in console mode









At any time you need after booting your system you want to change to gui mode the run

startx

If you want to restore Ubuntu’s GUI mode then



Open /etc/default/grub with your faviourite editor and change

GRUB_CMDLINE_LINUX_DEFAULT="text"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Update GRUB by running

sudo update-grub

To restore lightdm run

sudo update-rc.d lightdm defaults

That’s it
