Title:
[Regression] Computer should NOT shutdown from Guest or Standard user
while an Administrator user is still logged in
Status in “lightdm” package in Ubuntu:
Confirmed
Bug description:
Computer should not shutdown/restart from a Guest session or from a
Standard user session while there is still an Administrator user
logged in. This is a major regression from Ubuntu 12.04. This poses a
huge data loss potential.
The easy way to solve this is to follow 12.04's policy. The computer
can not shutdown/restart from any session while there are any other
session logged in regardless it is Administrator, Standard or Guest
session.
The hard way is to follow this proposed policy:
(A) Guest session can not shutdown/restart while there are any
sessions logged in regardless they are Standard or Administrator
users.
(B) Standard user can not shutdown/restart while there is an
Administrator user or another Standard user logged in.
(C) Standard user can shutdown/restart while there is a Guest session
logged in.
(D) Administrator user can shutdown/restart while there is a Standard
or Guest session logged in.
(E) Administrator user can not shutdown/restart while there is still
another Administrator user logged in.
1- In case of (A), a Guest tries to shutdown/restart, a message should
pop up telling the Guest that s/he can not shutdown/restart but the
session can be logged off, and maybe give a reason for that.
2- In case of (B), a Standard user tries to shutdown/restart, a
message should pop up telling the Standard user that s/he can not
shutdown/restart but the session can be logged off, and maybe give a
reason for that.
3- In case of (C), a Standard user tries to shutdown/restart, a
message should pop up telling the Standard user that s/he can
shutdown/restart but the Guest could lose their data if not saved on
external storage such as a USB stick, and advice him/her to log off
that session first then shutdown/restart.
4- In case of (D), an Administrator user tries to shutdown/restart, a
message should pop up telling the Administrator user that s/he can
shutdown/restart but other users could lose their data if not saved,
and advice him/her to log off those sessions first then
shutdown/restart.
5- In case of (E), an Administrator user tries to shutdown/restart, a
message should pop up telling the Administrator user that s/he can not
shutdown/restart but the session can be logged off, and maybe give a
reason for that.
