Force Quit Unresponsive Applictions (Linux Friday)

One of the hardest things for former Windows users to get used to is you can’t press Ctrl-Alt-Del to bring up the task manager. So what do you do when there is a program that has become unresponsive???

There is a simple solution and you actually have a couple different options.

Option 1: (my favorite, also the easiest)
The easiest way to quit a program that stopped responding is by using the force quit button. In Ubuntu this button can be added to any panel by right clicking on the panel and choosing ‘Add to Panel.’ Then scroll down and select ‘Force Quit.’

Then, when there is a program you need to stop, just click on the force quit button (which is now on your panel) and your mouse cursor will change into a set of cross hairs. At this point, click on the program window that you would like to stop. If you decide you don’t want to quit any programs after already clicking the force quit button, just press Esc to cancel.

Option 2:
The second way to stop an unresponsive program is to use the System Monitor. This can be found under System->Administration->System Monitor. I like to add the System Monitor to my top panel so I can keep tabs on what my computer is doing.This can be done by using the same process as above.

Once the System Monitor is running, click on the ‘Processes’ tab.

Then, similar to Windows, click on the process you want to stop and then click the ‘End Process’ button in the bottom right corner. One nice feature of the System Monitor is you can sort processes by name, status, CPU usage, and memory usage.

Option 3:
This option is for more advanced users, and those who wish to use the terminal. If you already know the name of the process you wish to terminate, all you need to do is type the following command:

killall process-name

Here, “process-name” is the name of the process you wish to terminate.

If you don’t know the name of the process, you could type in a command such as ‘top’ to see which programs are using the most resources.
