suspend on lock screen

[bash321]

thanks for the quick reply,
ill make that more obvious and clear next time,i am running a small print server at home and sometimes smb server locally....

I remember I had problem with using suspend in ubuntu a while back... in a dev release of 11.10 when it was still in beta stage..
i had fixed it using those commands links above...
i'm not sure how it does it. but im guessing the logitech keyboard sets off that command to the computer when i am logged in when i press the suspend button for that action to happen. then the pc goes into suspend.
is there away for this command to be initiated when i am at the lock screen of my ubuntu pc? when i am not logged in and i press the button on my keyboard? because at the moment it does not work.

the command im guessing is sudo pmi action suspend...
but it only occurs when i am logged in not when i wake up at the lock screen.. it use to initiate suspend i think in ubuntu 9.04 or 9.10? it doesnt work in 12.04.

This is not a keyboard solution but can you not at the log-on screen click on the gear at the top right and select suspend?

Not exactly what you are looking for, but should work, also you could set a very short time to suspend in the Power section in System Settings.

[bash321]

I can do that at the logon screen.
i can select i think shutdown restart not sure if there is suspend don't think so anyway.
but I cannot do that at the lock screen when i resume from suspend.
is there away to do this at the lock screen?
even if meant putting that button from the logon screen to the lock screen as well?

[bash321]

the power option is good as well in power management i will revisit that and have a brief look.
but it still would be good if i could manually put my pc to sleep using the sleep key on my logitech keyboard from the lockscreen, because then the computer would not randomly go to suspend when if i am reading an article for more than 5 minutes or watching a film using movie player. or going through automatic slideshow on LO or photo slideshow with shotwell and it randomly suspends because i haven't used the mouse and keyboard for more than 2 or 5 or 10 minutes.

My apologies, I don't suspend and don't lock screen, I mistook your saying unlock screen as logon screen.
Wasn't paying close enough attention, Sorry
