RHBA-2013:0390 - gnome-screensaver bug fix update

Synopsis

gnome-screensaver bug fix update

Type/Severity

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.
