command linesuspendxfce
When I click on the exit icon there is a suspend option. When I click this the computer suspends, which works really well. I want to create a custom key mapping on the suspend command XK86Sleep (ThinkPad sleep button) which I can create using the keyboard settings.
I have seen pm-suspend from numerous sources, but this requires root and so does not work. What command does XFCE use when pressing the Suspend option through the UI as described above?
XFCE 4.8, Ubuntu 12.04, ThinkPad T60
I do not know yet how to solve this problem; however, to manually suspend and lock the screen in KUbuntu (and perhaps Ubuntu?) I've aliased a command which I'm sure others can use -- so I want to post it here. I'm also going to reclaim the bounty and keep offering it until someone answers...
If you do:
sudo qdbus org.freedesktop.ScreenSaver /ScreenSaver Lock; sudo pm-suspend
This will first lock the screen and then issue a suspend command. Although sudo isn't needed for the first command, you'll want to enter the password before the screen locks because you'll have to unlock it to gain sudo ability to suspend if you don't.
Turns out we were all wrong. The magnet which triggers the lid sensor had come away inside the laptop. I confirmed this by holding a fridge magnet up to the camera. As soon as I did that, the laptop suspended fine. So I figured there's a magnet in the base. There was, but it was floating around (clinging to the battery) inside the machine. I put it back in place and it's now working.

Try using this for the command
