Title:
Desktop contents displayed on resume, before lock screen is shown
Status in gnome-screensaver package in Ubuntu:
Confirmed
Bug description:
I am running 14.04. When I resume from sleep, the contents of my
desktop (including any open windows, emails, etc) are displayed
onscreen briefly before the unlock screen is shown. This potentially
allows an attacker to view the contents of a locked screen.
To reproduce:
1) Suspend a machine, e.g. by closing the lid
2) Resume the machine
Expected results:
Upon resume, the first thing shown onscreen is the screensaver unlock screen.
Actual results:
Upon resume, the first thing shown onscreen is the set of open windows that
were displayed before the machine was put to sleep. After a second or two, the
unlock screen is drawn and you have to enter a password to unlock the machine.
This is reproducible on my system.
