How to add a button to lock & suspend

I just installed Ubuntu MATE 18.04, and I cannot find a way to add a “Shutdown” or “Suspend” button to the taskbar like in Xfce. The “Indicator Applet Complete” does have a kind of system button, but I have to click once more to actually trigger an action. On my previous Xfce setup, I used to have one button at the bottom-right to lock & suspend, and another one at the bottom-left to shutdown. Those have proved very convenient over the years.

I did find on the Internet some traces of “panel buttons”, but I haven’t found them yet. Can someone help?

Hi @rdiez, There should be a Shut Down... applet in Add to Panel

It looks like this when run:

I wish it included Logout like XFCE does, though. It does have Suspend.

Or is this the clicky one you refer?

It looks like the “Shut Down…” applet will do nicely for powering down, thanks.

However, the suspend option is not the same. I am used to suspend and lock with a single click (I do that several times a day). I am trying Ubuntu MATE in a KVM virtual machine now, which does not properly support suspending. On a normal PC or laptop, would suspend also lock the screen?

Is there a key combination for suspend+lock screen?
