I am using Xubuntu (an elegant and easy-to-use Linux distribution, based on Ubuntu, using Xfce as the graphical desktop). Xubuntu has shortcut for locking the screen. It is CTRL+ALT+Del. But, there was no shortcut for Suspend action (keeping the computer in Sleep mode).
If you would like to add keyboard shortcuts on Ubuntu, you may visit this link: Creating custom shortcuts on Ubuntu
Here is how to add shortcut for Suspend action on Xubuntu / Xfce:
– Go to Settings Manager
– Go to Keyboard
– Go to Application Shortcuts tab
– Click Add button
– Type the shortcut command for Suspend (the shortcut is xfce4-session-logout -s)
– Type the shortcut keys you would like for it (e.g. CTRL+ALT+S)
– It’s done.
Note: You can do man xfce4-session-logout or xfce4-session-logout –help for more information.
Here is how to add shortcut for opening Terminal on Xubuntu / Xfce:
– Go to Settings Manager
– Go to Keyboard
– Go to Application Shortcuts tab
– Click Add button
– Type the shortcut command for Terminal (the shortcut is xfce4-terminal)
– Type the shortcut keys you would like for it (e.g. CTRL+ALT+T)
– It’s done.
In this way, you can add shortcuts for other commands as well.
Below is the screenshot my computer’s shortcut keys. I have added a shortcut (CTRL+ALT+T) for opening Terminal. For locking screen, I have kept CTRL+ALT+L. For suspending computer, I have kept CTRL+ALT+Del.
Hope it helps.
Thanks.
