Prior to this update, running the system-config-display utility with the "--set-hsync" and "--set-vsync" command line options or setting these options in a kickstart file for Anaconda failed to create a "Monitor" section in the xorg.conf file. This update corrects this error so that the system-config-display utility now creates this section as expected.

The previous version of the system-config-display utility allowed the user to configure dual head mode regardless of the driver in use. Consequent to this, enabling dual head mode on a system with a video driver that does not support this feature (such as "nv") caused system-config-display to create a non-working configuration file. With this update, the utility has been adapted to disable dual head mode when such a driver is detected.

Previously, an incomplete dual head configuration could cause the system-config-display utility to terminate unexpectedly with a traceback. This update adapts the underlying source code to make sure that such an error no longer occurs.
