RHBA-2013:1706 - Bug Fix Advisory

Topic

Updated gnome-screensaver packages that fix two bugs are now available for Red
Hat Enterprise Linux 6.

Description

The gnome-screensaver packages contain the GNOME project's official screen saver
program. The screen saver is designed for improved integration with the GNOME
desktop, including themeability, language support, and Human Interface
Guidelines (HIG) compliance. It also provides screen-locking and fast
user-switching from a locked screen.

This update fixes the following bugs:

• Previously, when using the virt-manager, virt-viewer, and spice-xpi

applications, users were unable to enter the gnome-screensaver password after
the screen saver had started. This occurred only when the virtual machine system
used the Compiz composting window manager. After users had released the mouse
cursor, then pressed a key to enter the password, the dialog window did not
accept any input. This happened due to incorrect assignment of window focus to
applications that did not drop their keyboard grab. With this update, window
focus is now properly assigned to the correct place, and attempts to enter the
gnome-screensaver password no longer fail in the described scenario. (BZ#905935)

• Prior to this update, the gnome-screensaver utility worked incorrectly when

using an X server that does not support the fade-out function. Consequently,
gnome-screensaver terminated unexpectedly when trying to fade out the monitor.
This bug has been fixed and gnome-screensaver now detects a potential fade-out
failure and recovers instead of crashing. (BZ#947671)

Users of gnome-screensaver are advised to upgrade to these updated packages,
which fix these bugs.
