Autologin - Xubuntu

To enable autologin in Xubuntu:

• Open the file /etc/lightdm/lightdm.conf
          $ sudo leafpad /etc/lightdm/lightdm.conf
• Modify the value of the string "autologin-user" with the required user name
      Eg: autologin-user=MyLoginName
• Save the file
• Reboot/ restart

To enable autologin in Xubuntu10.04:

• Open the file /etc/gdm/custom.conf
          $ sudo mousepad /etc/gdm/custom.conf 
• Add these fields:
  
  TimedLoginEnable=false
  AutomaticLoginEnable=true
  TimedLogin=user_You_want_to_login
  AutomaticLogin=user_You_want_to_login
  TimedLoginDelay=30
• Save the file
• Reboot/ restart

Note:

• Make sure the user is created before modifying the file.
• You can use any text editor instead of leafpad/mousepad.

Setting proxy for Software center and Synaptic package manger (Xubuntu)

The proxy for APT can be set in Xubuntu by following these steps:

• Open a Terminal
• Open the file /etc/apt/apt.conf in an editor by entering the command:
  $ sudo leafpad /etc/apt/apt.conf &
  Note: The file may not exist initially.
• Include the following lines in the file:
  
  Acquire::http::proxy "http://<proxy>:<port>/";
  Acquire::ftp::proxy "ftp://<proxy>:<port>/";
  Acquire::https::proxy "https://<proxy>:<port>/";
  
  Eg: Acquire::http::proxy "http://192.10.12.13:8080/";
• Save the file
• Reboot/ restart

Note:

• If you need authentication include "<username>:<password>@" before the proxyserver name.
  Eg: Acquire::http::proxy "http://<username>:<password>@<proxy>:<port>/";
  Acquire::http::proxy "name:password@http://192.10.12.13:8080/";
• The proxy for Synaptic package manager can also be set from its menu. 
• Leafpad is a text editor. You can use any text editor instead of it.
• Do not forget the ';' at the end of each line. 
• The '&' at the end of the command opens the file as a new process. If it is omitted the Terminal window will be locked until the file is closed.

Add/change keyboard shortcuts (Xubuntu)

• How to:
1. Open the Settings Manager (Applications->Settings->Xfce4 Settings Manager)
2. Search for Keyboard.
3. Select the [Application Shortcuts] tab.
4. The existing keyboard shortcuts can be found here. They can be changed.
5. Click the add button to add your own.
• My favourites: I have customized the shortcuts to act just like in Windows:
• Hide all windows and set focus to Desktop: (Windows + d)
• To open the file explorer: You can add a new command to open any folder:
          thunar folder_path
          Eg: thunar /home/myname/d-drive
  Note: thunar is the default file browser in Xubuntu
