Disable Apport Error Report Dialog in Ubuntu 12.04

In fresh Ubuntu 12.04 installation, it keeps popping up annoying apport error report dialog on every log-in even after sending the error report. This simple tutorial will show you how to disable this dialog in Ubuntu.

Open up terminal from the dash home or press Ctrl+Alt+T, edit “/etc/default/apport” file with this command: 

sudo gedit /etc/default/apport
Set enable=0:
enable=0

Save the file, and done!

What is the HUD?

The HUD or Heads Up Display is a search-based alternative to traditional menus and is a brand new feature in Ubuntu 12.04.

Some apps like Gimp or Inkscape have hundreds of menu items. If you're using apps like these, you may remember the name of a menu option, but you might not remember how to find it in the menus.

Using a search box can be quite a bit easier and even faster than navigating complicated heirarchies of menus. The HUD also can be more accessible than normal menus as some people are unable to precisely control a mouse pointer.

It's easy to try the HUD:

1. Tap Alt to open the HUD.
2. Start typing.
3. When you see a result that you want to run, use the up and down keys to select the result, then press Enter, or just click your desired search result.
4. If you change your mind and want to exit the HUD, simply type Alt again or Esc. You can also click anywhere outside the HUD to close the HUD.

The HUD keeps track of your search history and adjusts the search results to be even more useful the more you use it.
