The Unity launcher is nice, and, like with Windows since version 7, you can pin – or “lock” – items to the launcher by right-clicking them when they’re running. For me, locking the System Monitor to the launcher was always one of the first things I had to do after setting up a new install of Ubuntu – though it could also be accessed by simply searching “system monitor” in the Unity dash. However, since upgrading to 13.04, I decided to try keeping a cleaner system, and that also meant not having a cluttered Unity launcher.
For me, some things are necessary to have on the launcher, such as my browser of choice, a link to LibreOffice and the files link to my Home directory. However, keeping things like Terminal and System Monitor seemed unnecessary, especially since there is already a shortcut to Terminal by default (CTRL+ALT+T). Being someone who was primarily a Windows user up until a little over a year ago, having a shortcut to an application that managed and monitored running processes was something I was used to and therefore depended on, and CTRL+ALT+Delete has always been the sacred keyboard combination for it. Luckily, setting up a keyboard shortcut in Unity to run its System Monitor isn’t difficult and only takes a minute to do, so long as you know the command for the shorcut.
- Go to System Settings > Keyboard and click on the Shortcuts tab.
- (Optional) If you’re assigning CTRL+ALT+Delete to open System Monitor, click on the System option under the category panel, click on Ctrl+Alt+Delete beside “Log out” and, when it says “New accelerator…” hit your backspace key to disable the shortcut.
- Click on Custom Shortcuts under the category panel.
- Click on the “+” icon below the shortcut list pane.
- In the field titled “Name:” type in the name of your shortcut (can be anything that tells you what it does).
- In the field titled “Command:”, type out the command you want the shortcut to process. In the case of running System Monitor, the command is gnome-system-monitor.
- Click on “Disabled” beside the name of your shortcut and when it says “New accelerator…” hit the key combination you wish to use for the shorcut on your keyboard, which you should then see listed in place of “Disabled” after you’re done.
