If you want to mount a partition upon startup in linux

You have to enter your partition information to /etc/fstab file. Then your disk will be mounted automatically!

Just go for following step:

• First take back up of /etc/fstab

  sudo cp /etc/fstab /etc/fstab.backup
  

• Execute following command to get your partition UUID information that will help you to configure /etc/fstab file.

  sudo blkid
  

  Search for your partition's UUID which you want to mount automaticall. Your HDD partitions shouls be displayed like:

  /dev/sda1: LABEL="Backup" UUID="00A0CE7EA0CE7A24" TYPE="ntfs"
  /dev/sda5: LABEL="40GBTWO" UUID="00A0CE7EA0CE7A24" TYPE="ntfs" 
  /dev/sda6: UUID="7550252c-3da7-4cd9-8da3-71e9ba38e74a" TYPE="ext4" 
  /dev/sda7: UUID="088fd084-a011-4896-aa93-c0caaad60620" TYPE="swap" 
  /dev/sdb1: LABEL="SaurK" UUID="0DB6254A58CEF6F7" TYPE="ntfs"
  

  and so on. It is just an example but format will be same.
• Now copy the UUID of the partitions which you want to insert in /etc/fstab file.
• Now open /etc/fstab file and insert entry for your HDD partitions on the last line of /etc/fstab file. Take help from previous entry, for format etc:

  sudo gedit /etc/fstab
  

  When opened your entry would be like this:

  UUID=<your_UUID_for_Disk_partitions> /media/<location_where_you_want_to_mount>             ntfs    errors=remount-ro 0
  

  Just an example:

  UUID=00A0CE7EA0CE7A24 /media/Backup               ntfs    errors=remount-ro 0
  

  you may have to replace ntfs to ext4 or fat32 according to the file system of your partition. It displays in blkid output.
• Now create location where to mount your disk partitions. Create a folder for each partitions to mount. ((note: a directory may be already created, if so ignore this step.) For example:

  sudo mkdir /media/Backup
  

• Then execute this command once finished:

  sudo mount -a

Terminator

There is one very interesting tool in Linux. It is called terminator and you can open multiple terminals within it. Before starting using it, it has been messy to work with multiple terminals at once. So to install this tool, run this command.

sudo apt-get install terminator

And you can split your screens just by clicking right mouse and choosing which way you want to split it (horizontally | vertically)

If your system settings is missing in Ubuntu

After I installed fresh copy of Ubuntu 14.10 on my machine I had only few settings on my settings panel, and I went like this for months. But it was child's play to fix this. I found command this from internet.

sudo apt-get install ubuntu-desktop

basically it re-installs Unity (Desktop environment of Ubuntu I guess). And you don't even need to restart and you have everything back.
