1.196.1. RHBA-2011:0456: xorg-X11-server bug fix update

Updated xorg-X11-server packages that fix three bugs are now available for Red Hat Enterprise Linux 5.
X.Org is an open source implementation of the X Window System. It provides the basic low-level functionality that full-fledged graphical user interfaces are designed upon.
This update fixes the following bugs:
* Prior to this update, running the X.Org server with the support for backing store enabled (the "backingstore" option) caused the server to occasionally terminate with a segmentation fault. With this update, the underlying source code has been modified to address this issue, and enabling the "backingstore" option in the server's configuration no longer leads to unexpected crashes. (BZ#690270)
* When running the X.Org server with the "r500" video driver, an attempt to use the system-config-display utility to enable dual head mode with the "Desktop layout" option set to "Individual Desktops" could render a user unable to move the mouse pointer between the screens. This update corrects this error, and the use of the "Individual Desktops" option no longer confines the mouse pointer to a single screen. (BZ#694728)
* Due to an error in the X.Org server, a user may have been occasionally unable to move the mouse pointer outside the area near the left edge of the screen. With this update, a patch has been applied to correct this error, and users are now always allowed to move the mouse pointer around the screen as expected. (BZ#695252)
All users of xorg-x11-server are advised to upgrade to these updated packages, which fix these bugs.
