I went to "System Settings", "keyboard", "shortcuts", "custom shortcuts", I added a custom shortcut and called it "task manager" in the "command line:" I typed "gnome-system-monitor", and I gave it the command, "ctrl+alt+del", I apply that and close it. Then I try it and get NOTHING...... why??
In fact, you cannot use
Ctrl+Alt+Del as your shortcut, because it is taken by a logout message, as I just checked:
In order to enable it, you have to go to the keyboard shortcuts you went before, and disable that shortcut or give it another key binding:
Then, you will be able to add your custom shortcut. In order for this to work for sure, you have to completely disable the other shortcut:
In order to do this, select the shortcut and press the
Now, you have to go to the Custom Shortcuts section and add a new shortcut, containing the following:
Name: Whatever relevant
I did this and it works fine in Ubuntu 12.04!
In the command-line(space for the command) you have to enter
How to find the command-
In linux to find a command to exicute a particular program you have to enter in the terminal the following command-
For e.g for the above example you will get a screen like this when you put
the 1st line "/usr/bin/programname" is the command you have to put/use/execute.
then add the key-binding(use something else like alt+cltr+menu.the one you used is assigned to something else) and save.It will work. :)
How to add in settings-
Open System Settings > Keyboard >Shortcuts tab > custom shortcuts >"+" button > in the name "System Monitor" or anything you want >in the Command space "/usr/bin/gnome-system-monitor" (all small case) > apply.
then click on the space where "Disabled" is writen and press the kay combination(other than alt+cltr+del.it is assigned to log out) for e.g as seen in picture, i had assigned alt+cltr+menu(the right-click menu button on the right of space bar)
if you still want to assign alt+cltr+del as the key binding,change the one for log out in the "system" option there and then assign it to this.
In the default configuration of Ubuntu 12.04 (do not know in others)
Ctrl+Alt+Del is set to close session shortcut. Make sure you have disable this or changed it to another shortcut.
(Sorry it is in Spanish, its the first line. It is deactivated)
Then you can set your custom shortcut to
(The last one)
If it does not work, try to restart your session (Not sure if reboot is needed) and check that the values are still the ones you set.
