Ubuntu Unity Program Launcher Desktop Dock Gone Missing

If you startup Ubuntu and find that the program icons are missing from the Launcher, and the Launcher itself is also gone, as well as the top-of-screen menu options, this means that something has gone wrong with the Ubuntu Unity desktop. Follow the instructions below to fix the problem. These steps have been tested with Ubuntu 14.04, but should also work with earlier versions.

  1. Press CTRL+ALT+F1, then enter your username and password to go to the command prompt.
  2. Enter this command:
    • sudo apt-get install unity
  3. Enter this command:
    • unity –reset
  4. Press CTRL+ALT+Delete to reset the computer.

You should now see the familiar program icons and menu bar at the top of the screen.

Ubuntu Software Center Search Box Missing

The Ubuntu Software Center normally has a search box in the upper right corner. However, if the window is sized slightly smaller than usual, that search box goes away. This is an error in how the responsive design of the interface was setup.

You can see examples below. The top example is of the window when it’s not sized large enough. The bottom example shows a slightly wider view. Click either image for a larger view.

A better method would be to resize the icons or have a ‘more’ indicator button to expand out and see other options.

Ubuntu Linux: Create an ISO Image from CD or DVD


Follow these instructions to create an ISO image from a CD or DVD.

  1. Insert CD or DVD.
  2. Run Terminal.
  3. Run the following command:
    cat /dev/sr0 > cd_ISO_output_name.iso
  4. Another command that may work is:
    dd if=/dev/cdrom of=~/cdrom_image.iso

In Ubuntu, you can use the Disks utility to find your drive ID name. In the example above, it is sr0.

The resulting ISO image should show up in your home folder, but you can choose any destination you’d like by placing the path before the file name, such as /home/Desktop.

To test the ISO image, double click on it and view its contents.
