Comment 10 for bug 942709

You might also want to consider disabling the automatic crash dialog, so it does not pop up in the middle of a screencast or screenshot if something goes wrong.

You can do it by editing its configuration file on the terminal, by running the following command and changing the 'enabled=1' line to 'enabled=0'

sudo nano /etc/default/apport

Alternatively, if you're comfortable with running the 'sed' utility on the terminal, you can do it in one go by executing:

sudo sed -i -e 's/\(enabled=\)1/\10/' /etc/default/apport
