And here it is..
- ‘Lock’ is a better term than ‘Screen Lock’ (since it affects more than just the screen)
- Suspend is typically activated by closing the lid on a laptop or with a power button on a tablet
- The power button on desktop machines isn’t always easily accessible
- Log out and switch user don’t make sense to people on single user systems (what are they logging out of, exactly?)
- Suspending a system doesn’t typically involve using the user menu:
Laptops – you close the lid
Desktops – leave it to go to sleep
Tablets – press the hard button
There isn’t something to add, Allan is pretty much clear about the new design that is still under progress and not final. What I want to emphasize is what Gnome developer Colin Walters said:
“Remember the recommended way to shut down GNOME 3 is to log out, and then shut down from the login screen; the Alt key is more of a hidden easter egg.”
That came as answer on Paul Burnham who proposed a solution for keyboard-less devices (ie tablets) :
“Another suggestion would be to determine if a physical keyboard is present, and if not display both “Suspend” AND “Power Off” menu items.”
This issue has been solved as you can see on the above image, but I am just emphasize the semantic significance of Logout before Shut Down. Speaking of semantic differences you can also check out the difference between Login and Lock screen.
