Binary package hint: ubuntu-docs
In "If you have been using Windows" document, there is two wrong descriptions on how to logout and standby. In the "Glossary of Windows Terms" section, there is:
"Log Off
To close all your programs and leave the computer ready for someone else to log in, choose System ▸ Quit..., then Log Out."
in fact, there is no 'Quit' dialog anymore, a user can directly logout by choosing 'System ▸ Logout xxx...', where xxx is the user name.
Same issue with 'Standby' in the same section, there is:
'Standby
To put your computer into a power-saving mode until you resume using it, choose System ▸ Quit..., then Suspend or Hibernate. (Hibernate requires no power at all, but is slower, and is not available on some types of computer.)"
it must be 'System ▸ Shutdown...'.
Confirmed for both 8.10 and 9.04. The wording has been changed in the alpha release to reflect the behaviour of 8.10. But it's still wrong since shutdown/logout is no longer available from the system menu.
