change runlevel in ubuntu
There is ni /etc/inittab file in Ubuntu because Ubuntu has /etc/event.d/rc-default file
You can fix this problem by editing /etc/event.d/rc-default file
First backup file,
Open vi /etc/event.d/rc-default
Find all lines read as - telinit 2 and replace with telinit 3
Reboot the system 
You can fix this problem by editing /etc/event.d/rc-default file
First backup file,
Code:
sudo cp /etc/event.d/rc-default /etc/event.d/rc-default.bakup
Code:
sudo vi /etc/event.d/rc-default
Code:
telinit 3

Debian Linux
Debian, as well as most of the distributions based on it, like early Ubuntu, does not make any distinction between runlevels 2 to 5.
ID | Description |
---|---|
0 | Halt |
1 | Single-User mode |
2-5 | Full Multi-User with console logins and display manager if installed |
6 | Reboot |
[edit] Ubuntu
Ubuntu 6.10 (Edgy Eft) and later contain Upstart as a replacement for the traditional init-process, but they still use the traditional init scripts and Upstart's SysV-rc compatibility tools to start most services and emulate runlevels.

gnd problem
之前已發現allegro中,gnd的rat已沒有顯示,
不過當時還以為如果沒有電氣連接,
在DRC check中可以檢查出來,
不過這次的電機控制板說明,是不可以的,
現在可以想到的解決辦法,
只能手工把這些網路連接起來。
