RHBA-2013:0390 - Bug Fix Advisory

Topic

Updated gnome-screensaver packages that fix several 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, NVIDIA hardware did not support the X Resize and Rotate Extension

(xRandR) gamma changes. Consequently, the fade-out function did not work on the
NVIDIA hardware. With this update, xRandR gamma support detection code fails on
NVIDIA cards, and the XF86VM gamma fade extension is automatically used as a
fallback so the fade-out function works as expected. (BZ#648869)

• Previously, the mouse cursor could be moved to a non-primary monitor so the

unlock dialog box did not appear when the user moved the mouse. This bug has
been fixed and the mouse cursor can no longer be moved to a non-primary monitor.
As a result, the unlock dialog box comes up anytime the user moves the mouse.
(BZ#744763)

• Previously, the shake animation of the unlock dialog box could appear to be

very slow. This was because the background was updated every time the window's
size allocation changed, and the widget's size allocation consequently changed
every frame of the shake animation. The underlying source code has been modified
to ensure a reasonable speed of the shake animation. (BZ#752230)

• When a Mandatory profile was enabled, the "Lock screen when screen saver is

active" option in the Screensaver Preferences window was not disabled. This bug
could expose the users to a security risk. With this update, the lock-screen
option is disabled as expected in the described scenario. (BZ#759395)

• When using dual screens, moving the mouse did not unlock gnome-screensaver

after the initial timeout. The users had to press a key to unlock the screen.
The underlying source code has been modified and the user can now unlock
gnome-screensaver by moving the mouse. (BZ#824752)

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