Esqueceu a senha do Ubuntu?

Pode recuperá-la da seguinte maneira :

Ao bootar o computador aparecerá a tela do Grub. Caso isso não aconteça, pressione a tecla ESC logo após a BIOS ter carregado.

No menu do Grub, aparece a expressão “(recovery mode)” . Seleccione essa opção.

A computador começará o processo de boot, mostrado todos os passos. Depois de um tempo aparecerá uma tela com o título de “Recovery Menu”. Utilize as setas do teclado e selecione a opção “root – drop to root shell prompt”.

No prompt, para alterar a senha do root digite:
passwd

Para alterar a senha de outro utilizador, digite o comando passwd seguido do nome de utilizador.

Por exemplo, para alterar a senha do utilizador Filipe, utilize:
passwd Filipe

Caso não se lembre do nome de utilizador utilize o comando  ls /home e aparece-lhe os nomes de utilizador existentes.

Após terminar de reconfigurar as suas senhas, digite exit para voltar ao menu. Seleccione a opção “Resume – Resume normal boot” para continuar o boot e entrar no seu desktop.

This explains how you could run a script made by you (say /usr/local/my_script) when you plug a specific USB device.

1. First run lsusb to identify your device. Example:
$lsusb
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 040a:0576 Kodak Co.
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

2. After doing this you know that
- the vendor ID of your device is 040a
- the product ID of your device is 0576

3. Now is time to create your UDEV rule:

Code:
sudo nano /etc/udev/rules.d/85-my_rule.rules

4. And add the text

Code:
ACTION=="add", SUBSYSTEM=="usb_device", SYSFS{idVendor}=="040a", SYSFS{idProduct}=="0576", RUN+="/usr/local/my_script"
Explanation:
When the usb_device product identified as 0576 of vendor 040a is added, run /usr/local/my_script
Note that ‘==’ and “!=” are comparators, while = and += are assingments
